Breakdowns are almost exclusively caused by drivers not servicing their vehicle often enough, or not taking proper care to ensure the vehicle is roadworthy before taking off.
Only stop if you have to, and try to find a safe spot to pull over. Pull over and park as far to the left as possible and activate your hazard lights - leave them on even if you have left the road.
When broken down:
Slow down to approximately 30 km/h lower than the signed speed limit when passing a breakdown.
If you are having trouble stop
Tyre pressure and tread depth need to be kept at safe levels. Make sure your vehicle’s tyres are in good condition and have a tread at least 1.5mm deep
In case of a tyre blowout, grip your steering wheel firmly and compensate for any pull to the side(s).
Don’t panic or brake immediately and try not to oversteer in response to a pull to one side. Slow down gradually once the vehicle is under control, and look for somewhere to pull over. Keep in mind that your vehicle can behave in an unknown way based on the road conditions.
Stalling at the wrong places can be very dangerous. You should always use your hazard lights to warn other road users if your car stalls. If you’re unable to restart the engine and there is no immediate danger, push the vehicle out of danger. Make sure to put it in a neutral gear before pushing.
If your vehicle continues at the same speed or accelerates when you release the accelerator, it could be stuck. Try to depress the clutch in a manual vehicle (or placing the gear in ‘NEUTRAL’ if automatic), and then apply firm pressure on the brakes without causing the wheels to lock.
