What to Do If Your Car Breaks Down
25 November 2025
Breaking down at the roadside is something every driver dreads. Understanding what to do if your car breaks down, who to call, and how to stay safe can make a difficult situation much easier to handle. This guide covers everything you need to know, from immediate safety steps to how to prevent breakdowns in the future.
Pull Over Safely and Stay Visible
If your car begins to lose power, make strange noises, or show signs of a fault, your first priority is to get to a safe place.
Move your vehicle to:
- The left-hand side of the road
- A lay-by
- A hard shoulder (motorways only)
Turn on your hazard lights immediately to warn other road users. If visibility is low, also use your sidelights.
If you’re on a motorway, leave the vehicle through the passenger-side door and stand well away from the road behind a barrier if possible.
Switch Off the Engine and Assess the Situation
Once stopped safely, turn off your engine. If you can do so safely, pop the bonnet to signal to other motorists that you’ve broken down.
Only carry out checks if you are in a secure location. Never inspect your car on the motorway or in fast-moving traffic.
Use a Warning Triangle (If Safe)
A warning triangle can help drivers see you sooner. Place it 45 metres behind your vehicle, but never use a triangle on a motorway, as it is too dangerous to walk behind your car.
Call for Breakdown Assistance
If you’re thinking, “My car broke down, who do I call?” here are the main options:
1. Your Breakdown Cover Provider
If you have a membership with AA, RAC, or Green Flag, call them first using the number on your membership card.
2. Your Insurance Company
Some car insurance policies include roadside breakdown assistance.
3. A Local Garage
If you don’t have breakdown cover, you can call an independent recovery service or a trusted garage.
Looking after your car and tyres is probably the best way to avoid a breakdown before it even happens. If you would like to have your car checked for warning signs or simply require any further information regarding car safety, find your nearest Setyres branch and our expert staff will help with any queries you may have.

Know What Information You’ll Need to Provide
When calling for help, be ready to give:
- Your exact location (using What3Words is helpful)
- Your vehicle registration
- A description of the issue
- Any dashboard warning lights showing
- Whether you’re in a safe place
This ensures faster, more efficient assistance.
Stay Safe While You Wait
While waiting for help:
- Stand away from the vehicle
- Keep pets and passengers safe behind a barrier
- Avoid sitting inside the car unless you’re in a secure place
- Keep your phone charged by carrying a portable charger
If you frequently drive long distances, consider keeping an emergency breakdown kit in your boot.
Common Causes of Why Cars Break Down
Understanding the most common causes of breakdowns can help you spot issues early.
1. Tyre or Wheel Problems
Punctures, blowouts, or damaged tyres are among the biggest causes of roadside breakdowns.
Keep your tyres in good condition and check tread depth regularly. If you’re in need of new tyres, Setyres have an extensive range, see our options here.
2. Battery Failure
Cold weather, short trips, or old age can cause a battery to fail. If your car struggles to start or feels sluggish, book a diagnostic check.
3. Overheating
Low coolant levels, radiator issues or water pump faults can cause overheating.
4. Electrical Problems
Modern vehicles rely heavily on electronics. Faults can trigger dashboard lights or prevent the car from starting.
5. Engine or Transmission Issues
Strange noises, lack of power, or knocking sounds should never be ignored.
Simple Checks You Can Do to Prevent Breakdowns
You can reduce your chances of breaking down with a few quick checks:
Check Your Tyres
Inspect for low tread, cracks, bulges or uneven wear. Uneven wear could indicate alignment or suspension issues, so book a check if needed.
Monitor Fluid Levels
Check oil, coolant, brake fluid and screen wash regularly.
Look Out for Warning Lights
Never ignore dashboard lights, they’re an early sign that something's wrong.
Book Regular Servicing
Regular servicing helps identify problems before they become severe. Book yours online here.
