Why should you slow down when you see this sign?
- A To reduce the risk of a blow-out
- B To avoid splashing others with water
- C To avoid throwing up loose chippings
- D To prevent grit from blocking your air filter
Why this is the answer
This sign is usually accompanied by a reduced speed limit. When chippings fly out from your tyres, they can cause a lot of damage to other vehicles, or injury to pedestrians, cyclists and motorcyclists. Slowing down will reduce the risk.
Why the other answers don't fit
- A
- To reduce the risk of a blow-out — A blow-out comes from a damaged or under-inflated tyre, not from the surface alone.
- B
- To avoid splashing others with water — Splashing is a wet-weather problem; loose chippings are dry.
- D
- To prevent grit from blocking your air filter — Your air filter is not what the sign is protecting.
