DSA Advice: Driving In Wet Weather

Timely advice from the DSA about wet-weather driving:

Rule 227

In wet weather, stopping distances (PDF, 125KB) will be at least double those required for stopping on dry roads. This is because your tyres have less grip on the road.

In wet weather

• you should keep well back from the vehicle in front. This will increase your ability to see and plan ahead
• if the steering becomes unresponsive, it probably means that water is preventing the tyres from gripping the road. Ease off the accelerator and slow down gradually
• the rain and spray from vehicles may make it difficult to see and be seen
• be aware of the dangers of spilt diesel that will make the surface very slippery
• take extra care around pedestrians, cyclists, motorcyclists and horse riders

Rule 121

Brakes affected by water. If you have driven through deep water your brakes may be less effective.

Test them at the first safe opportunity by pushing gently on the brake pedal to make sure that they work. If they are not fully effective, gently apply light pressure while driving slowly. This will help to dry them out.

With all the rain we’ve had, people really need to take notice of this advice.
