Final Answer:
In heavy rainfall, most cars will begin to lose traction and hydroplane between speeds of 35-55 miles per hour.
Step-by-step explanation:
Hydroplaning is a hazardous condition that occurs when a vehicle's tires lose contact with the road surface due to a buildup of water between the tires and the pavement. In heavy rainfall, this phenomenon becomes more pronounced, posing a significant risk to drivers. The critical speed range at which most cars are susceptible to hydroplaning is between 35-55 miles per hour.
At these speeds, the water on the road cannot be effectively displaced by the tire treads, causing the tires to ride on a thin film of water, leading to a loss of traction and control. Driving within this speed range in heavy rain increases the likelihood of hydroplaning, making it crucial for drivers to exercise caution and adjust their speed accordingly. Hydroplaning can result in a lack of steering response and braking effectiveness, potentially leading to accidents.
Therefore, it is essential for drivers to be aware of the prevailing weather conditions and adjust their driving behavior accordingly, such as reducing speed and increasing following distances. Adhering to these precautions can significantly enhance road safety during adverse weather conditions, reducing the risk of accidents associated with hydroplaning.
