Driving in flood & heavy Rain

Flooding can happen any time thanks to rain, blocked drains, burst water mains, tides and burst river banks.

You’ll probably hear warnings of sea or river-related flooding from the Environment Agency, or on the news, but surface water flooding from heavy rain or drains that can’t cope is harder to predict and can be very localised.

If you hear there’s flooding on the way, move your car to higher ground to stop it getting damaged. Water plays havoc with electrics and can even cause airbags to go off suddenly some time later.

Heavy rain

  • Turn your headlights on – the Highway Code says you must use them when visibility is seriously reduced (less than 100m).
  • Use fog lights if you like, but switch them off when visibility improves.
  • Leave twice as much space between you and the car in front – it takes longer to stop in the wet.
  • If your steering feels light due to aquaplaning, ease off the accelerator and slow down gradually.
  • If you break down don’t prop the bonnet open while you wait. Rain-soaked electrics can make it harder to start the engine.
