A. The contact between the tyres and the roadway deteriorates
B. Wheel-spray can impair visibility
C. Braking distances are greater
Explanation:
Why must the safe distance maintained be much greater on a wet roadway than on a dry roadway?
Option A: On wet roads, a layer of water forms between the tyres and the road surface, reducing friction and traction. This makes it easier for the vehicle to skid, hence, a larger distance is needed to safely control and stop the vehicle.
Option B: Water sprayed from the wheels of vehicles, especially at high speeds, can obscure visibility for drivers behind. This reduced visibility requires a greater distance to react to sudden stops or obstacles.
Option C: Wet road conditions significantly increase braking distances. Water reduces tire grip, meaning it takes more time and distance for a vehicle to come to a complete stop.
