Summary 
This section contains the following topics: 
•  Introduction 
•  Purpose 
 
Introduction 
The ‘Prevention First’ strategy requires Police to focus on preventing crime and crashes 
before they happen. 
 
Police seek to reduce death and injury on our roads. In line with this strategy, road 
policing patrols must focus on prevention of offences and unsafe behaviour. This 
includes: 
•  deterring and detecting offending through intelligence led targeting of specific risk 
locations, behaviours, people and organisations 
•  general deterrence and positive reinforcement of safe behaviours through intelligence 
led high visibility patrols in risk locations and at risk times, as informed by 
intelligence. 
 
Purpose 
This chapter applies to all constables and authorised officers, hereafter referred to as 
‘Police’. It gives detailed instructions on: 
•  your powers to stop vehicles 
•  how to plan patrols 
•  carrying out vehicle stops 
•  interviewing drivers. 
 
Apply TENR at all times during the planning and execution of a vehicle stop.

Vehicle search 
 
Enforcement powers 
Police may stop, enter, search vehicles, and seize evidential material in certain 
circumstances as authorised in various legislation. You may also search vehicles for 
people in certain legislated circumstances. Ensure you are fully aware of your powers. 
 
Where statute authorises Police to stop a vehicle for a specific period of time, any 
extension to that detention will be considered by a court in terms of reasonableness of 
Police action in the circumstances. 
 
Powers for stopping vehicles 
Police in an approved Police uniform or wearing a distinctive cap, hat or helmet (with a 
badge of authority affixed to it) on the roadside, or in a vehicle displaying flashing lights 
or sounding a siren, have the power to stop the driver of a vehicle as follows:

Section 30 & 32 of the S&S allow the 
 
establishment of an authorised road block 
to arrest a person who is unlawfully at 
large or a person who has committed an 
offence punishable by imprisonment 
where there are grounds to believe such 
persons are in a vehicle. Section 32 also 
allows the stopping of vehicles at the road 
block or in the vicinity of the road block. 
 
Once stopped you can only demand the 
details of the occupant of the vehicle who

When enforcing the LTA or related 
 
legislation, under section 113(2)(a) LTA 
an enforcement officer may direct a 
person on a road to provide (one or more 
of) his or her details as follows provided 
that the particulars are for enforcing the 
provisions of the LTA or other legislation 
specified in section 113(1) LTA: 
•  full name, 
•  full address, 
•  date of birth, 
•  occupation, 
•  telephone number 
•  any other particulars as to his or her 
identity, and 
•  information to identify the driver or 
person in charge of a vehicle. 
 
Note: A person on a road can also be 
required to provide information leading to 
the identification of a person in charge of 
a vehicle (unless the person has been 
detained or arrested), provided the 
information requested is for the purposes 
of s113(1) and 113(2)(a) LTA. 
 
There is no power under the LTA to 
demand the details of a passenger in or 
on a vehicle if they are not suspected of 
committing an offence as outlined above. 
Once you have stopped a vehicle under 
 
the S&S Act, section 10 S&S allows you to 
require the details of the person in that 
vehicle suspected to be unlawfully at 
large or o have committed an offence 
punishable by imprisonment. 
 
Note: There is no power to demand the 
details of all occupants of the vehicle 
under section 10 S&S, unless they are all 
suspected of being unlawfully at large.

Risks associated with vehicle stops 
This section contains the following topics: 
•  Always consider the risks 
•  Known-risk vehicle stops 
•  Unknown-risk vehicle stops 
•  Contact and cover principle 
 
Vehicle stops are unpredictable and may be dangerous. 
 
Vehicle stops are classified as: 
•  known-risk vehicle stops, where Police have information about the vehicle and its 
occupants 
•  unknown-risk vehicle stops, where Police have no information about the vehicle and 
its occupants. 
 
Always consider the risks 
You must always consider the risks, applying TENR, before undertaking a vehicle stop. 
 
The risks may not become apparent until you approach the vehicle or interact with the 
driver. Safety precautions help protect you, your colleagues and the public. 
Note: When stopping vehicles, be sure not to create a road hazard by disrupting traffic. 
 
Known-risk vehicle stops 
Known-risk vehicle stops occur when Police stop a vehicle knowing that its occupants 
may present a risk to Police (and public) safety. This information might come from: 
•  an unfavourable QVR response, such as: 

danger flags 

wanted reference 

unlawfully taken 
•  the occupants are known to pose a risk to Police, or 
•  the vehicle is suspected to have been used to commit an offence. 
 
If you are about to undertake a known-risk stop, you must adopt tactics to mitigate the 
risks. See the contact and cover principle below. 
 
Unknown-risk vehicle stops 
Unknown-risk vehicle stops occur when the Police do not have specific information to 
indicate a risk to employees. Most vehicle stops fall into this category but never-the-less 
you must treat these stops with caution. 
 
Contact and cover principle 
The contact and cover principle involves identifying and communicating the roles of 
each officer in any interaction with a potential suspect. 
Contact officer 
Cover officer 
•  makes the contact 
•  remains detached from the interaction 
•  checks the licence 
•  observes the scene for risk indications. 
•  conducts roadside interviews/searches. 
 
A second patrol can adopt the cover role for single crewed units or if the officers involved 
are inexperienced. 
 
Note: If a single crewed unit attends to the driver without a cover officer or cover patrol 
car, regular contact with the Communications Centre (Comms centre) must be made. 
Refer to the ‘Procedure before you stop a vehicle’ section later in this chapter.

Types of patrol 
This section contains the following topics: 
•  Mobile patrol 
•  Stationary patrol 
•  Useful resources 
 
Mobile patrol 
The objectives of a mobile patrol are to: 
•  be seen, particularly in high risk locations at high risk times 
•  deter and detect crime and/or offenders 
•  improve driving standards by setting an example 
•  respond safely to incidents. 
 
Stationary patrol 
A stationary patrol reminds the public of the Police presence, encouraging safe driving 
and deterring crime and other offending. 
 
It is used at maximum visibility locations in heavy traffic flow and high risk locations, 
such as dangerous intersections and high crash areas. 
 
Useful resources 
•  National Road Policing Guide 
•  Prevention Guide: Road Policing

Plan and prepare for patrol 
This section contains the following topics: 
•  Plan the patrol route 
•  Uniform requirements for traffic patrol 
 
Plan the patrol route 
Police is committed to intelligence led policing. From a Road Policing perspective, this 
means deploying to meet risk. 
 
Districts must focus on identifying specific road policing risks, especially those related to 
crash promoting behaviours, and the tactics that will be used to reduce them. These 
tactics are contained in Safer Journeys generally located in the District Tasking (RIOD) 
and Coordination SharePoint application (login required) as: 
•  real time taskings 
•  monthly taskings, and 
•  tactical taskings 
depending on how your district manages its road policing staff and addresses its road 
policing risks. 
 
As part of your patrol planning you should familiarise yourself with key risks in your 
area, wherever located. You and your supervisor need to determine what patrol actions 
will have the greatest impact on crash reduction. Other intelligence sources may be 
available to assist you. Use your local knowledge along with other information and 
intelligence to determine where you will be the most effective. 
 
Use information to predict where and when you can make the best differences. 
•  target to risk from intelligence products, i.e. crash maps, and ask colleagues about 
local trouble spots 
•  are any potential major road blockages, events at sports grounds or special functions 
scheduled that may cause traffic problems. 
 
When your patrol is interrupted, for example to attend an incident, you should revert to 
your plan once the incident has been dealt with. 
 
Uniform requirements for traffic patrol 
All employees undertaking traffic stops at night must wear the high visibility long-
sleeved safety jacket or the high visibility long-sleeved raincoat, as part of their uniform 
in compliance with the Police Manual chapter ‘Uniform, dress standards and appearance’- 
‘Requirements when wearing uniform’. 
 
The high visibility sleeveless safety jacket may only be worn during daylight hours, as it 
does not comply with the night time high visibility standard of the Australia and New 
Zealand Standard  AS/NZS 4602:20119. 
 
Uniformed employees must wear uniform headgear for all work outside vehicles or 
buildings.

Before you stop a vehicle 
This section contains the following topics: 
•  Principles 
•  Stop a vehicle 
•  Procedure before you stop a vehicle 
 
Principles 
Conduct each vehicle stop safelyeffectivelylawfully and professionally
Remember to: 
•  use the contact and cover principle, and 
•  constantly be aware safety, not just road safety. 
 
Stop a vehicle 
There are four procedures to follow: 
•  Before you stop a vehicle 
•  Alert the driver and position your vehicle 
•  Approach the vehicle 
•  Interview the driver. 
 
Procedure before you stop a vehicle 
Follow these steps before you stop a vehicle. 
Step Action 

Observe activity in the vehicle such as occupants preparing firearms, hiding 
evidence or acting suspiciously. 
 
Caution: If you suspect the occupants have firearms, you must stop the 
vehicle in accordance with the High Risk Vehicle Stops (within your PITT 
training) procedure while applying TENR. 

Know why, and plan how, you are going to stop the vehicle applying TENR. 

Where appropriate use your Mobility device to log the 3T, prior to engaging 
with the driver. Do not hesitate to use the radio if any safety concerns arise, 
prior to or during the vehicle stop - communicate the location, event and 
concerns to the Communications Centre (Comms) via the radio. 
 
When notifying Comms of a 3T, advise Comms of any safety concerns, 
including: 
•  the person(s) who would commonly use the vehicle being stopped 
•  an occupant of the vehicle 
•  location 
•  registration of vehicle stopped. 
 
•  Using the radio also gives other patrols awareness of your location if you 
require assistance. 
4 Assess 
the 
risk. Consider the: 
•  known history of the owner and occupants 
•  proximity of the nearest back-up patrol. 

If there are suspicious circumstances, advise Comms of: 
•  the vehicle’s direction of travel 
•  a description of the occupants 
•  how you plan to stop the vehicle 
•  your back up requirements.

Version : 12.0  

Request back-up early if needed based on any real or potential threats 
identified from your risk assessment. Follow the vehicle and stop it only once 
back-up is present. 

Decide where you will stop the vehicle. Above all, the place should be safe 
and well lit in a built-up area where you have plenty of room to move. 
 
For public safety, there should be: 
•  no obstructions 
•  no risk of crash 
•  room for the occupants to get out safely. 
Note: Avoid stopping on corners or outside licensed premises.

Alert the driver and position your vehicle 
This section contains the following topics: 
•  To alert the driver 
•  To position your vehicle 
 
To alert the driver 
Once you have selected a suitable location to stop the vehicle, based on TENR, alert the 
driver by following these steps. 
Step Action 

Activate your vehicle’s blue and red lights and use the siren to indicate your 
intention to the target driver. 
 
Note: It is recommended that you always activate your siren, even if it seems 
unnecessary. It will assist you in supporting a case of failing to stop or failing 
to remain stopped. In such cases you must satisfy the court that the driver 
had clearly heard and seen the patrol vehicle. 

Where possible, while following the driver keep to the right so they have a 
clear view of you in their interior and exterior mirrors. 

Use your indicators to signal your intention to pull over to the left. Then use a 
hand signal or the PA system to direct the driver to stop in a safe location. 

Check the traffic behind you. 

Once you have attracted the driver’s attention, and it is obvious the driver is 
pulling over, immediately cover the brake and be ready to brake in a 
controlled manner. 

Allow a safety margin in case the driver panics and brakes abruptly. 

If you are in an unmarked car, allow a greater safety margin than usual 
because of a possible delay in the driver’s response. 

Keep a watch on activities inside the car at all times. 
 
To position your vehicle 
Once have you alerted the driver, position your vehicle by following these steps and 
applying TENR throughout. 
Step Action 

Once the driver understands they are required to stop, allow them to stop 
safely. 

Slow down carefully and position your vehicle approximately a car length 
behind the other vehicle and 1 metre to the right of their vehicle. 

Position your vehicle to create a safety zone in which to walk towards the 
other vehicle.

Approaching a vehicle 
Vehicle approach procedure 
Follow these steps when initially approaching a vehicle and apply TENR. 
Step Action 

Where appropriate use your Mobility device to log the 3T, prior to engaging 
with the driver. Do not hesitate to use the radio if any safety concerns arise, 
prior to or during the vehicle stop - communicate the location, event and 
concerns to the Communications Centre (Comms) via the radio. 
 
When notifying Comms of a 3T, advise Comms of any safety concerns, 
including: 
•  the person(s) who would commonly use the vehicle being stopped 
•  an occupant of the vehicle 
•  location 
•  registration of vehicle stopped. 
 
Using the radio also gives other patrols awareness of your location if you 
require assistance. 

Before you get out of your vehicle, consider: 
•  your reason for the stop 
•  the number or type of occupants 
•  location 
•  surrounding traffic 
•  back-up availability. 

At night, use your forward facing ‘take down’ lights only briefly to scan the 
inside of the suspect vehicle. 
Caution: Do not leave the ‘take down’ lights switched on, as they reduce the 
contact officer's vision of the suspect vehicle. 

Decide whether it is appropriate to turn your flashing blue and red lights down 
to the secondary setting; and check that ATIS has been activated (where 
fitted) before taking the keys out of the patrol vehicle ignition. 

Use the contact and cover principle to approach the suspect vehicle. Discuss 
these roles with your partner, so each knows what the other is doing. 

Always remove the patrol vehicle’s ignition keys before leaving the vehicle. 

Use the safety zone created by the patrol vehicle's position to protect you 
from passing traffic. 

If you are the contact officer, it is usual to approach the driver’s side of the 
vehicle scanning for hazards as you approach. Follow these steps: 
•  pause at position “A” (see diagram below) long enough to make contact 
with the driver and assess any danger 
•  move past and stand at position “B” for any interview and interaction with 
the driver. Note: this position allows you to keep both the driver and 
approaching traffic in view 
•  stand in position “C” in instances of heavy traffic flow. It may be safer to 
approach the vehicle from the passenger side.

Approaching the driver 
Driver approach procedure 
Follow these steps when approaching the driver and apply TENR. 
Step Action 

Where there is risk of drive-off, instruct the driver to turn off their ignition. 

If a driver refuses your request to remain in the car, invite the driver to the 
side of the road near the rear of the car (see picture below). From this 
position, the cover officer can observe the interview and you can withdraw to 
the Police vehicle if necessary. 
 

Never stand or conduct an interview in the area between the two cars. If your 
patrol vehicle is struck from behind, it may be shunted forward and into the 
suspect vehicle. 

If the driver gets out of the vehicle: 
•  ask them to return and stay seated in the vehicle, and 
•  if this request fails, follow step 2 above.

Interviewing the driver 
This section contains the following topics: 
•  Identify yourself 
•  Interview 
•  When interviewing 
•  Why this approach is successful 
•  How to interview 
 
Identify yourself 
If the vehicle has been stopped because you believe an offence, other than a driving 
offence, has been committed, the contact officer must: 
•  if not in uniform, identify themselves by name 
•  produce evidence to show they are a Police employee (if not in uniform) 
•  if you intend to search the vehicle for a person or evidential material, you must 
comply with section 131 S&S Act 2012. You must: 

identify yourself by name or unique identifier 

if not in Police uniform produce identification 

announce your intention to enter and search the vehicle 

state the reason for the search 

state the act under which the search is taking place (S&S Act). 
 
See ‘Vehicle search’ for further details. 
 
Interview 
The first 60 seconds are the most important, as this is considered the critical period in 
the officer/driver roadside interaction. 
The incident or occurrence from the driver’s perspective may be considered ‘negative’ 
from the point the vehicle is stopped until they are spoken to by the contact officer. The 
contact officer sets the scene for the interaction in the first 60 seconds. 
 
When interviewing 
Don’t . . . 
Do . . . 
•  apologise for the stop 
•  be courteous, confident and positive 
•  show any outward signs of annoyance, 
without being confrontational 
anger or irritation 
•  keep your approach neutral and fair 
•  react to any smart, patronising or 
•  be alert for danger and constantly 
irritating remarks from the driver or 
monitor the vehicle occupants’ actions, 
occupants 
as well as passing traffic and 
•  be drawn into an argument (keep 
pedestrians 
conversation to a minimum) 
•  always ‘keep your cool’. 
•  cause a driver to lose face, especially in 
front of their family or friends 
•  threaten the driver 
•  delay the driver unnecessarily. 
 
Why this approach is successful 
This approach is successful because: 
•  it reduces potential for conflict in traffic enforcement and helps maintain public co-
operation 
•  when used consistently, the public knows what to expect and that reduces uncertainty 
and the potential for conflict 
•  it is sure and reliable and improves officers’ confidence and professionalism 
•  it aligns with the principles of Service First.

How to interview 
Follow these steps when interviewing people stopped in their vehicles. 
Step Action 

Greet the driver by: 
•  saying “Good morning, sir/madam/driver” (for example) until you find out 
their name. 
 
Consider introducing yourself by name and station. 

Explain firmly yet politely the reason for the stop. For example, “I have 
stopped you because I checked your speed at 70 km/h in a 50 km/h area”. 
NoteDo not ask the driver if they know why the car has been stopped. This 
invites a denial and subsequent confrontation. 

Ask for an explanation for the driver’s actions and: 
•  listen attentively without interrupting or commenting 
•  note the explanation in your notebook to use as evidence later if necessary. 

Ask for their driver licence to verify the driver’s identity. Check the contents of 
the licence including that: 
•  the picture is an accurate likeness 
•  it is not expired 
•  the driver has the appropriate class of licence to drive that vehicle 
•  any restrictions or conditions on the licence are complied with. 
 
Keep the licence temporarily if you intend to issue an infringement offence 
notice (ION) or if you intend to prepare a charging document. Ask for the 
driver’s particulars (section 114(3)(b) LTA): 
•  full name 
•  full address 
•  date of birth 
•  occupation 
•  telephone number 
•  state whether they are the owner of the vehicle or not 
•  give the vehicle owners name and address. 
 
After this, you may address the driver by name. 
 
Note: Mobility allows you to quickly scan a driver licence, Transport Service 
Label label or, Road User Charges label and vehicle licence label to enable 
quick check against details held in NIA (including Driver Licence version). This 
data can then be used to populate an ION or WTW if required. 

Conduct a passive breath test on the driver. If appropriate, continue 
breath/drug test procedures in accordance with the ‘Alcohol and drug impaired 
driving’ chapter. 

Inspect the vehicle for defects. 
•  Check that the front registration plate number matches the rear. 
•  Check and note the Evidence of Vehicle Inspection (WOF or COF label) and 
licence label expiry dates, and that all relevant details match. 
•  Be alert for evidence of other offending, including criminal or drug related 
matters. 
 
Note: Refer to the Safe Driver – Safe Vehicle video for further guidance. 

If appropriate or necessary, return to the patrol vehicle to confirm the 
information and details given by a QV, QP or QDL.

Discretion - a certain level of discretion is permitted when considering what is 
the most appropriate action. See the ‘Speed enforcement’, ‘Traffic compliance 
scheme’ and ‘Written traffic warnings’ chapters of the Police Manual for further 
information. 

If an offence notice is required, tell the driver you are going to issue one. 
•  Fully complete the notice. 
•  Explain the details of the notice to the driver. 
•  Hand back the driver licence with the notice. 
10 
Leave your patrol car’s warning devices on until the stopped vehicle has safely 
re-entered the traffic flow and you have moved off, or out of the safety zone 
position to the side of the road. 
 
Note: These steps relate to exercising your powers as conferred by section 114 LTA, 
which gives Police the authority to stop and speak with a driver for traffic related 
offending. You need to be familiar with those powers.
