Roads become slippery under these conditions
Why do roads become very slippery?
1. When it has been raining for an hour or more.
2. The day after it rains.
3. For the first 10 to 15 minutes of a rainstorm.
4. Right after the rain has stopped.
Final answer:
Roads become slippery when it has been raining for an hour or more, the day after it rains, for the first 10 to 15 minutes of a rainstorm, and right after the rain has stopped.
Explanation:
When it has been raining for an hour or more, roads can become very slippery due to the accumulation of water on the road surface. This water reduces the friction between the tires and the road, making it harder for the tires to grip the road, leading to increased skidding and sliding.
Furthermore, the day after it rains, roads can also be slippery as the residual moisture on the road surface can still reduce friction. Even though the rain has stopped, the road may still be wet, and this can make driving conditions hazardous.
During the first 10 to 15 minutes of a rainstorm, roads can be slippery as the rainwater mixes with oil and gasoline that leaks onto the road surface from cars. This combination creates a slick film on the road, decreasing traction and increasing the likelihood of skidding.
Right after the rain has stopped, roads can remain slippery for a short period of time. The water may not have evaporated or drained away completely, and this can make the road surface wet, reducing friction and causing slippery conditions.
Why do roads become slippery when it has been raining for an hour or more? Roads become slippery when it has been raining for an hour or more because the water accumulation reduces friction between tires and the road, making it harder for tires to grip the road surface.
