Driving in wet weather

Driving in wet weather can be hazardous as wet roads can mean reduced visibility and grip on the road.

Be prepared

  • Is your journey essential? can you delay your journey until after the rain / flooding as subsided?
  • If you do have to travel plan your journey in advance and try to avoid areas that are prone to flooding.
  • Check that your windscreen wiper blades are in good condition. If not get them replaced.
  • Make sure all your lights are working.

Driving on wet roads

  • Use dipped headlights so that other drivers can see you.
  • Adjust your speed and drive for the conditions. Give yourself time to react, slow down if spray is reducing visibility.
  • Leave plenty of room between you and the vehicle in front. It takes at least twice as long to stop on wet roads that it does on dry ones.
  • Slow down if you have to drive through standing water. You could lose control of the steering and aquaplane if your tyres lose contact with the road.

Driving through floods

  • Avoid driving through floods if you can.
  • Never drive through water if you are unsure of the depth. Take the long way round rather than risk your safety:
    • Just 15cm of water will reach the bottom of most cars; the depth the water could cause possible loss of control or stall the car.
    • Many cars will start to float in as little as a 30cm of water. Causing you to lose control of the car.
    • 60cm of free flowing water can sweep away most vehicles including large 4x4’s.
  • If you have to drive through flood water:
    • Drive on the highest section of the road. This is usually the middle.
    • Consider other drivers and properties.  Drive slowly so you don’t cause a bow wave.
    • Test your brakes as soon as you can after leaving the water.
    • Never drive through fast-moving water. Your car could easily be swept away.
  • Watch your speed. Roads may have unexpected patches of water that are hidden by a dip or bend in the road. Driving at speed into water that is 15cm deep can feel like driving into a brick wall.
