Vehicle mechanical problems It is important to keep your vehicle working properly. If your vehicle breaks down while you are driving, it can be dangerous as well as inconvenient. If your vehicle is having mechanical problems that require you to stop, remember the following for your safety:
• Change lanes safely and park in a safe location, if possible.
• Do not stop on a bridge or in a tunnel. This can be very dangerous.
• If the vehicle is left in a potentially dangerous location, turn on your hazard lights (four-way flashers).
• Raise your hood.
• Carry reflective triangles. On the highway or in a location that is potentially dangerous, safely place reflective triangles to the rear of your vehicle, about 10 to 20 metres (33 to 66 feet) apart.
• Do not try to do roadside repairs on crowded or fast-moving highways.
• If it is a potentially dangerous situation, have all occupants leave the vehicle and wait at a safe location to the rear and away from the vehicle, as shown in the diagram. DO NOT WAIT IN THIS AREA Move away from the vehicle while waiting for help. If a motorist stops to offer help, you could ask them to call for assistance.Text extracted from the PDF for reference and may contain layout artefacts. The official PDF is authoritative.
