Breakdowns And Incidents

Rule 275

If you need to stop your vehicle in the event of a breakdown or incident, try to stop in a place of relative safety. A place of relative safety is where you, your passengers and your vehicle are less likely to be at risk from moving traffic.

The safest place to stop is a location which is designed for parking. On motorways and other high-speed roads, the safest place to stop is a service area. Other places of relative safety include:

  • Lay-bys
  • Emergency areas (see Rule 270)
  • Hard shoulders (see Rule 269).

Be aware that hard shoulders provide less protection than other places of relative safety because they are so close to high-speed traffic.

You and your passengers should, where possible, keep well away from your vehicle and moving traffic. Otherwise moving traffic could collide with your vehicle, forcing it into you and your passengers.

Rule 276

If your vehicle breaks down, think first of all other road users and;

  • Get your vehicle off the road if possible
  • Warn other traffic by using your hazard warning lights if your vehicle is causing an obstruction
  • Help other road users see you by wearing light-coloured or fluorescent clothing in daylight and reflective clothing at night or in poor visibility
  • Put a warning triangle on the road at least 45 metres (147 feet) behind your broken-down vehicle on the same side of the road, or use other permitted warning devices if you have them. Always take great care when placing or retrieving them, but never use them on motorways
  • If possible, keep your sidelights on if it is dark or visibility is poor
  • Do not stand (or let anybody else stand) between your vehicle and oncoming traffic
  • At night or in poor visibility do not stand where you will prevent other road users seeing your lights

  • If it's dark or visibility is poor, use sidelights.

Get safe

  • Exit your vehicle by the side furthest from traffic, if it is safe and possible to do so, and ensure passengers do the same
  • Put on high-visibility clothing if you have it and it is within easy reach
  • Get behind a safety barrier where there is one, but be aware of any unseen hazards such as sudden drops, uneven ground or debris

Rule 278

To rejoin the carriageway after a breakdown from

  • A hard shoulder, build up speed, indicate and watch for a safe gap in the traffic. Be aware that vehicles, obstructions or debris may be present on the hard shoulder
  • An emergency area, you MUST use the emergency telephone provided and follow the operator's advice for exiting the emergency area. A lane may need to be closed so that you can rejoin the carriageway safely.

[Law RTA 1988 section 36]

Rule 279

Disabled drivers. If you have a disability that prevents you from following the above advice in Rules 277 and 278, you should:

  • Switch on your hazard warning lights
  • Stay in your vehicle and keep your seat belt on
  • Call 999 immediately and ask for the police. Alternatively, press your SOS button if your vehicle has one and ask for the police.

Rule 280

If anything falls from a vehicle on to a motorway or other high-speed road, DO NOT remove the obstruction yourself. Stop in a place of relative safety (see Rule 275) and call the emergency services on 999.

On other roads, you should only remove obstructions if it is safe to do so.

Rule 281

Warning signs or flashing lights. If you see emergency or incident support vehicles displaying flashing lights in the distance, be aware there may be an incident ahead (see Rule 219). You should slow down and be prepared to move safely into another lane or stop.

The emergency services, traffic officers and recovery workers may be required to work in the carriageway; for example, dealing with debris, collisions or conducting rolling roadblocks. You MUST follow any directions given by police or traffic officers as to whether you can safely pass the incident or obstruction.

[Laws RTA 1988, sections 35 &163, and as amended by TMA 2004, section 6]

Rule 282

When passing the scene of an incident, remain alert for hazards (such as debris or slow-moving vehicles) and do not slow down unnecessarily (for example, if an incident is on the other side of a dual carriageway). You should focus on the road ahead when passing an incident because a lack of attention may cause a further incident, collision or congestion (see also Rule 283).

Rule 283

If you are involved in an incident or collision or stop to give assistance

  • If possible, stop in a place of relative safety (see Rule 275)
  • Use your hazard warning lights to warn other traffic
  • Put on high-visibility clothing if you have it
  • Ask drivers to switch off their engines
  • Ask drivers and passengers to stop smoking
  • Contact the emergency services on 999 and provide full details of the incident location and any casualties. Use an emergency telephone, a mobile telephone, or press the SOS button if your vehicle has one (see Rule 277 on how to identify your location on a motorway or other high-speed road)
  • Move uninjured people away from the vehicles to a place of relative safety (see Rule 275)
  • DO NOT move injured people from their vehicles unless they are in immediate danger
  • DO NOT remove a motorcyclist's helmet unless it is essential and you are trained to do so
  • Be prepared to give first aid (see Annex 7 and Useful websites)
  • Stay at the scene until the emergency services arrive
  • Be prepared to exchange details (see Rule 286).

If you are involved in any other medical emergency, you should contact the emergency services in the same way.
