Driving licence test

What should you do if you are driving in a waterlogged lane?

It is not good to drive through pools of water like the one in the picture for several reasons:

  • You do not know what is in the water; perhaps there is a big rock at the bottom?
  • The brakes may deteriorate if a lot of water gets into the system.
  • Increased risk of aquaplaning (but not particularly high here).
  • You risk splashing someone or something.

You should therefore avoid driving through the water pool, but since it is a curve you cannot edge into the oncoming lane without risk. A compromise is the best solution. The benefits of “Drive at low speed and keep to the left, but inside my lane”:

  • Less risk of driving into, for example, a rock concealed by the water, since the wheels are not in the deepest section. The low speed reduces the risk of damage if you drive into something.
  • The impact on the brakes is minimised as there is less water being sprayed up when you drive through the shallowest part at low speed.
  • Reduced risk of aquaplaning and splashing since you are driving in the shallowest part of the water and your speed is low.
  • Reduces the risk of crashing into another car compared with the option of edging into the oncoming lane.
