Question

Under which of the following conditions is the road likely to be most slippery?

a) after it has rained for several hours
b) a few minutes after it starts to rain or following a light drizzle
c) when center-lane markings have just been painted
d) when the highway is new and first used by the public

Answer 1

The road tends to be most slippery a few minutes after it starts to rain or following a drizzle, owing to the mix of oil and gasoline on the road surface with water.

Step-by-step explanation:

The road is likely to be most slippery a few minutes after it starts to rain or following a drizzle. This is because when it rains lightly, oil and gasoline that have leaked onto the road surface mix with the water, creating a slick and dangerous surface. Oil and gasoline on the road can significantly reduce control of the car. In contrast, heavy rain can help by washing away the oil and gasoline, although the road may still be slick.
