Car permit · Night and weather
When do road surfaces become especially slick?
Correct answer: In the first 10 to 15 minutes of rainfall.
Answer options
- AJust after the rain has come to an end
- BOnce it has rained steadily for an hour or more
- CIn the first 10 to 15 minutes of rainfall Correct
Why
When rain first falls, it lifts oil and grease from the pavement and forms a slick film until enough rain washes it away, which usually takes 10 to 15 minutes. Slow down as soon as the first drops hit your windshield.
