safe-driving
Why must speed be reduced on a wet roadway?
- Slippery conditions can reduce tire grip and cause a skid or hydroplane
- The posted limit automatically becomes a minimum speed in rain
- Wet pavement improves braking, so speed should be increased
- Rain affects only vehicles with worn tires
Answer: Slippery conditions can reduce tire grip and cause a skid or hydroplane. Water reduces the tires’ contact and grip, increasing the chance of a skid or hydroplaning. A posted number does not guarantee that speed is suitable for current pavement conditions, and wet roads do not improve braking. The worn-tire choice is too narrow because even a properly maintained vehicle must adapt to water. Ease off the accelerator before the vehicle loses traction, and avoid abrupt braking or steering. A strong cue is visible water on the roadway: adjust speed early, while the tires still respond normally.
