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.
