Final answer:
To avoid hydroplaning, a driver should slow down below 35 mph, as this allows for better water displacement by the tires and reduces the risk of losing traction and control of the vehicle. option b is correct.
Step-by-step explanation:
To avoid hydroplaning, a driver should slow down below 35 mph. Hydroplaning occurs when a vehicle's tires encounter more water on the road surface than they can scatter or displace. When this happens, the water pressure in the front of the tire pushes water underneath the tire, causing the tire to be separated from the road surface by a thin layer of water. Losing traction, the vehicle can then slide uncontrollably as if it were on ice.
To prevent hydroplaning, it's critical to reduce speed in heavy rain or on wet roads, especially if the speed limit is around 35 mph or higher. Drivers should also ensure their tires are properly inflated and have good tread depth, which helps with water displacement.
Therefore, the mention correct option to avoid hydroplaning is to slow down below 35 mph.
