What should you do if your car breaks down on a public road or your vehicle has broken down on a motorway?
The key topics in this section explain the procedures for emergency breakdowns and how far you should place a warning triangle from your car.
CAR BREAKDOWNS: The Highway Code has the answers in the vehicle breakdowns and incidents section.
The British Highway Code covers all the regulations for drivers breaking down on public roads. This section deals with car breakdowns.
It also lists the rules and safe procedures for handling roadside emergency incidents. Check through Highway Code rules 274 to 287.
Rule 274: The priority should always be considering the safety of all other road users. Find a way to warn other motorists because a broken down car or truck may endanger other traffic.
If safe to do so, you should attempt to remove your vehicle from the road. This is especially important if it causes an obstruction for other road vehicles.
Modern cars and trucks have hazard warning lights fitted. Switch on the hazard lights to alert other traffic of your broken down vehicle.
Make yourself as conspicuous as possible. You can achieve this by wearing a reflective or a fluorescent jacket. Wearing light-colored clothing at night time makes you easier to see in the darkness.
Leave vehicle sidelights turned on during darkness or poor visibility. Never stand between oncoming traffic and your vehicle. Avoid standing directly in front of your vehicle's driving lights to help keep it visible to other road users.
Is a warning triangle a legal requirement in the United Kingdom? All motor cars first registered from the 1st of July 2006 must carry at least one emergency reflective warning triangle by law.
If your car has broken down on a motorway how should you place your warning triangle? Place a Highway Code hazard triangle (or similar vehicle breakdown sign) on the same side of the road of any carriageway.
Note: A warning triangle distance from car should be at least 45 metres (147 feet) and placed behind the vehicle. Do not use a highway breakdown triangle if you encounter a broken down car on a motorway.
Vehicle breakdowns while driving on motorways in the United Kingdom are very dangerous. What if you suspect your vehicle is developing a mechanical problem on a motorway?
Try to leave the motorway at the soonest available service area or motorway exit. If this is not possible, follow the proper procedures for emergency car breakdown on motorways.
Rule 275 to 278: You must obey all Highway Code extra motorway breakdown rules for driver and passenger safety. Be familiar with the list of recommendations for drivers.
Rule 279: If an object falls onto the highway from a vehicle you should stop your car when it is safe. Only attempt to retrieve the obstruction only if you can do so safely.
Rule 280: You should not attempt to remove a motorway obstruction by yourself. The guidelines are to stop at the next available emergency telephone. That is where you can contact the Motorway Highways Agency or call 999 to inform the police.
Rule 281: Police Officers and HA Traffic Officers display Highway Code warning signs. They also use rear-facing red and blue flashing lights while working in the carriageway. They use these Highway Code lights to make road users aware of a traffic incident ahead.
You should reduce your speed and prepare to stop your car if you see or hear emergency vehicles in the area.
You Must follow all Police or Traffic officers' directions for safe passing of an incident or road blockage.
