Frequently Asked Questions

Since we introduced Traffic Officers on our network in September 2009 we have received a number of queries from customers asking about the roles and responsibilities of our Traffic Officers, about the vehicles used and the equipment that is carried in them.

Traffic Officers are responsible for:
• managing incidents, except where there is a loss of life, injury or potential criminal activity
• setting signs and signals and answering emergency roadside telephones
• arranging the removal of damaged or broken down/abandoned vehicles in partnership with the police
• removing debris and other obstructions from the carriageway
The role of a Traffic Officer involves:
• managing incidents that do not involve loss of life, injury or potential criminal activity
• supporting the police when they are managing incidents, particularly in managing traffic
• high visibility patrols to reassure the public
• dealing with accident damaged, broken down and abandoned vehicles
• providing rolling road closures to hold traffic back to allow removal of debris, installation of temporary traffic management and other purposes
• providing temporary road closures
• clearing debris, animals and found property from the network
• identification of defects and potential improvements to the network
• monitoring roadworks
• planning arrangements for forthcoming special events
educating road users
The Traffic Officers have powers to:
• Stop traffic and close roads, lanes and carriageways;
• Direct and divert traffic
• Place and operate traffic signs;
• Manage traffic and traffic surveys.

Failure to comply with a Traffic Officer’s directions or sign is an offence and could lead to:
• A fine of up to £1,000
• Driving Licence endorsement; or
• Disqualification.

Assaulting, wilfully obstructing or impersonating a Traffic Officer is an offence and could lead to a fine of up to £5,000 or Imprisonment.


The Welsh Government has instigated this service to both improve journeys for drivers, to make roads safer and to allow police to focus on tackling crime.

The benefits include:
• Reduced incident-related congestion
• Increased journey-time reliability
• Reduced secondary incidents – the incidents that happen at the scene of an existing incident or at road works
• Freeing up police time to focus on core activities, such as tackling crime and enforcing the law.
• Making the road networks safer


With the Traffic Officer Service taking on routine trunk road tasks; police will be able to spend more of their time concentrating on their priority of enforcing the law and dealing with crime.


The decision on who attends an incident depends on which resource is closer to the scene. Traffic Officer Vehicles have red and amber lights and are not allowed to exceed the speed limit. Each incident will be assessed and the most appropriate resources will be deployed to the scene. It is a matter for each police force how they deploy their resources.


Traffic Officers do not have powers to arrest people, however it is an offence not to comply with their requests.

Failure to comply with a Traffic Officer’s directions or sign is an offence and could lead to:
• A fine of up to £1,000
• Driving Licence endorsement; or
• Disqualification.


The vehicles have amber and rear-red flashing lights on their vehicles and are easily recognisable, as they have yellow and black livery on them.

It must be remembered that the Traffic Officer Service is not an emergency service.

Traffic Officers are not allowed to exceed the speed limit when responding to an incident however we would ask drivers to allow them to pass if they see them on the highway as it may be the case that they are going to the scene of an incident which may be holding up traffic.


Given the nature of their role and the environment that Traffic Officers work in, ensuring their safety of staff and that of the travelling public is important.

Traffic Officers deal with a range of incidents, some of which involve incidents where persons have been injured, and we may be first on the scene and need to make the incident safe before the arrival of the required emergency services and therefore the need to be highly visible is crucial.


Welsh Government funds the Service to operate a three vehicle resilient fleet.


The NWTMC off the A55 at Junction 17 Conwy, operates 24 hours every day of the year, collecting information on road and traffic conditions across Welsh motorway and trunk roads.

It provides a central information point for the motorway and trunk road network, collecting real time information from road sensors and CCTV cameras as well as reports from the Traffic Officers, police forces, local highway authorities, contractors, and weather centres.

This real time information is then made available to drivers who have a choice of how they access it.

Drivers can log onto the Traffic Wales website or call the 24-hour automated telephone service on 0300 123 1213. Information is also available through traffic bulletins on radio and TV.

Information about travel conditions is also be provided through electronic roadside message signs located at key locations on the motorway and trunk road network, giving drivers the opportunity to change route if there is a problem ahead.


Traffic Officers carry out a range of duties, from arranging removal of damaged and abandoned vehicles to stopping and directing traffic.

They also provide a safe working environment on the motorway for the fire and rescue service, police and ambulance service to carry out their duties effectively.

If Traffic Officers arrive first at the scene or the emergency services have received a call from a mobile phone we are able to provide fast, accurate information to them, including marker post details.


A rolling road closure is when we use the Traffic Officer vehicles to gradually slow down the following motorists and then stop them temporarily to allow enough time for maintenance work to be carried out, or for debris or an incident to be cleared in safety.


Before going out on road, at the start of every shift a POWDER Check is carried out.

This includes the following:

Petrol – or diesel in our case – does the vehicle have enough fuel?

Oil – A quick check is always advisable.

Water – We check the coolant and washer fluid, and some drinking water is a good idea too.

Damage – a quick visual check of the bodywork to make sure everything’s okay.

Electricity – are all lights and electrical controls working as they should be? Particularly important for Traffic Officer vehicles, with our added lights and matrix signs.

Rubber – We check the tyres – they’re the vehicle’s only contact with the road and are crucial for driving, and stopping, safely.


The way in which Traffic Officer Vehicles are positioned on the hard shoulder when attending incidents is known as vehicle orientation or ‘fending’ and there are generally three options that can be adopted.

These are:

  • Fend in – this is when the front of the vehicle is positioned towards the verge
  • Fend off – when the front of vehicle is positioned towards the carriageway
  • In line – when the vehicle positioned parallel to the carriageway.

When attending an incident, Traffic Officers are instructed to conduct a risk assessment to determine the most appropriate fending option to adopt in order to deal with the incident.


Traffic Officers will put out cones and lights, if needed, to improve the visibility of our vehicles and to provide a safe working area and clear information to approaching drivers. It is also to avoid our vehicles being struck by errant vehicles and to ensure the safety of the public and our staff.


Traffic Officers patrol at the speed of traffic in lane one, and on quieter motorways at not more than 60mph. Traffic Officers are not allowed to break the national speed limit.

In maintaining this practice it provides a balance between not holding up traffic whilst being able to spot a broken down vehicle and bring our vehicle safely to a stop at the correct distance behind that vehicle which is approximately 25 metres behind a broken down vehicle.
