When driving in heavy rain or downpour with our vehicle, we must first brake more gently to prevent the wheels from skidding, since the grip of the wet road will be less than if it were dry.
We will also moderate our speed to have more reaction time, even stopping the vehicle if necessary, and we will leave a greater safety distance with the vehicle in front of us to avoid a possible collision.
If the downpour is very intense, we will stop the vehicle and look for a safe place to park until it passes, leaving the parking lights on.
