Bridges and overpasses
- tend to form ice on their surfaces before other road surfaces do ✓
- are not generally as slippery as the rest of the road
- lose their coat of snow first because it melts quickly
- are usually not as slippery as they look with snow on them
Answer: A. tend to form ice on their surfaces before other road surfaces do
Bridges and overpasses tend to form ice on their surfaces before other road surfaces do.
Why this is the answer
The handbook lists bridges and overpasses as a hidden danger and states directly that they tend to ice up before other road surfaces. That means you should expect a bridge or overpass to be slick even when the road leading to it looks fine. The passage gives no support for treating them as less slippery or quicker to clear, so the only choice that matches the handbook is the one about ice forming early.
Why the other answers are wrong
- B. are not generally as slippery as the rest of the road — The handbook does not say bridges and overpasses are less slippery; it warns that they can form ice earlier than other surfaces.
- C. lose their coat of snow first because it melts quickly — The passage does not say bridges and overpasses lose snow first, and its warning about early ice points the other way.
- D. are usually not as slippery as they look with snow on them — Calling them not as slippery as they look goes against the handbook's warning to treat bridges and overpasses as a hidden danger.
Remember it
When the road looks clear, think "bridge first" — expect ice there before the rest of the road.
