Final answer:
The true statement is 'd. all of the above', which includes tips to avoid hydroplaning, handling wet brakes, and understanding when roads are most slippery due to oil and gasoline on the surface, especially after light rain.
Step-by-step explanation:
The statement that is true regarding driving conditions and safety is: d. all of the above. This includes:
- Avoiding hydroplaning by slowing down when it rains and ensuring tires have the correct air pressure and good tread to maintain control.
- Brakes may become wet and lose effectiveness after driving through deep water or in heavy rain, which can cause pulling to one side or reduced function; in which case, you should slow down and gently press the brake pedal until they work properly again.
- Roads are most slippery just as rain begins, due to the oil and gasoline that has leaked onto the road surface not yet being washed away.
When cars travel, they may leak oil and gasoline onto the road, which can adversely affect car control when it rains lightly, as these substances can create a slippery layer on the road. A heavy rain might wash away these leaks more thoroughly, but it can also lead to hydroplaning if water pools on the road surface.
