Once you’ve completed all the above checks, you’re ready to set off on your journey.
5. Take it slowly.
Don’t risk your safety or other road users for the sake of speed. Visibility is poor when driving in heavy rain, so adjust your driving accordingly.
Increase the distance between you and other drivers: Poor visibility means it takes longer for drivers to spot and respond to hazards. Giving other road users space increases your ability to see hazards and plan your response.
When a road is very wet, it takes double the time and distance to stop. The two-second rule, applied in fair weather conditions, becomes the four-second rule. Avoid braking hard, as this increases the chance of skidding.
Aquaplaning: When a car loses its grip on the road because of surface water, steering, and braking can feel light and unresponsive. If this happens, don’t panic. Gently ease off the accelerator until you feel control returning.
Stop: Always consider pausing your journey if you need to. Pull over where it is safe to do so and continue once the weather conditions improve.
6. Be considerate of other road users.
It can be tempting to use full-beamed headlights and fog lights when driving in the rain. However, neither are advised as they dazzle other road users. Dipped headlights are sufficient to increase your visibility without blinding other drivers.
7. Standing water.
Always treat puddles, standing water, and floods with extreme caution. Never enter moving water, or drive into water deeper than 10cm. If you must go through standing water, slow down to around 5 miles per hour. Enter the water one car at a time and drive slowly along the highest point in the road. Don’t stop your car, or you may flood your exhaust – an expensive problem to repair.
Once you’re clear of the water, pump your brakes in short bursts to test and dry them thoroughly.
