Roads are often slipperiest
Correct answer
- in the morning.
- during the second hour of rain.
- during the first half hour of rain.
Explanation
Roads are often at their slipperiest during the first 30 minutes of rain. This is because the rainwater loosens and mixes with dirt, oil, and other fluids that have built up on the pavement, creating a slick surface. This slippery condition will persist until more rain washes those substances away.
