Final answer:
Drivers should increase their following distance in rainy conditions as it takes longer for a car to stop on wet pavement and the reaction time of a driver adds to the total stopping distance.
Step-by-step explanation:
Drivers should increase their following distance in rainy conditions.
In rainy conditions, the road becomes slippery and it takes longer for a car to come to a stop. By increasing their following distance, drivers allow themselves more time to react and brake, reducing the risk of a collision.
For example, a study showed that on wet pavement, the stopping distance for a car traveling at 30.0 m/s was significantly longer compared to dry pavement. The reaction time of a driver also adds to the total stopping distance.
