Standing in front of the open hood of her vehicle in the middle of winter, a woman is on the phone to seek assistance.

A car breakdown can happen at any time on the road. Dead battery, flat tires, mechanical failures such as an alternator or clutch problem, or overheating—here’s how to act quickly, effectively, and safely.

What to do if your vehicle breaks down on the road?

  • If a breakdown occurs while you’re behind the wheel, follow these steps to get through it safely:
  • Pull your vehicle to safety. Take the next exit if you can, or move as far to the right as possible on the shoulder.
  • Turn on your hazard lights immediately.
  • Raise the hood to signal that you need assistance.
  • Place emergency flares behind your vehicle.
  • Only exit your vehicle if necessary, always from the passenger side. Otherwise, stay buckled inside, especially on a busy road or in poor weather conditions.

Are your children or pets also on board?

  • Lock the doors to keep them secure.
  • Keep them warm with an emergency blanket in winter, or open the windows to cool them down in summer.
  • Stay calm and speak in a soothing voice to reassure them.
  • Do not try to chase after a pet that escapes, especially in the dark.

What to do if your vehicle is stopped on a dangerous road?

If your vehicle is stopped on a bridge, in a tunnel, or on a busy road:

  • Stay in your vehicle and call 9-1-1 to secure the area.

When and how to call Roadside Assistance?

Once you are out of danger, contact your Roadside Assistance service or an emergency road service.

  • Call from your vehicle if you have a cell phone.
  • Otherwise, ask a passerby to make the call for you, but never get into a stranger’s vehicle.
  • Provide the dispatcher with your name, vehicle make and model, location, and the nature of the breakdown. Also give your licence plate number and a phone number where you can easily be reached.
  • Note the estimated arrival time.
  • When the patroller arrives, confirm that the towing service is the one you called.

Pay attention so you can describe where you are in the event of a breakdown. The information you provide will help speed up the Roadside Assistance response by allowing the service technician to bring the right equipment. Note the following:
  • Streets, intersections, and landmarks.
  • Note the highway on- and off-ramps you used.
  • Don’t rely solely on your GPS—navigation systems can fail, especially in remote areas.

What to do to prevent breakdowns?

Here are a few tips to reduce the risk of a car breakdown on the road:

At the first sign of trouble, consult your repair shop. Make sure your spare tire and tools are always in good condition and ready to use when needed.

What emergency kit should you keep in your car?

Get a roadside emergency kit to keep in your car at all times. What should a roadside emergency kit contain?

  • Flashlight and basic tools
  • Reusable water bottle filled before you leave
  • First aid kit
  • Emergency blanket

Find an emergency kit for your car at the CAA-Quebec Boutique and earn CAA Dollars if you are a member.

Winter tip: Never leave without a few extra layers of clothing (socks, mittens, a warm sweater, a toque…) for each passenger in the vehicle.

A car breakdown on the road can be stressful. But by keeping the right reflexes, you’ll reduce the risks and gain peace of mind. Regular vehicle maintenance remains the best way to prevent mechanical breakdowns and hit the road with confidence.
