Allow a larger space cushion than usual when stopping:
- On an incline. ✓
- At an intersection.
- At a stop sign.
- At a toll plaza.
Answer: A. On an incline.
Leave a bigger space cushion than usual when you stop behind another vehicle on an incline.
Why this is the answer
The handbook's list of situations that call for more following distance includes being stopped behind another vehicle on an incline. The reason it gives is that the vehicle ahead may roll back before it starts moving forward, so the extra room keeps you clear if that happens. The same passage also ties extra space to wet roads, low visibility, being passed, and carrying a heavy load or pulling a trailer.
Why the other answers are wrong
- B. At an intersection. — The handbook does not list intersections as a place where you need a larger-than-usual cushion when stopping; its list names inclines, bad weather, low visibility, being passed, and heavy loads or trailers.
- C. At a stop sign. — A stop sign is not among the situations the handbook gives for adding extra stopping space, so nothing in these passages supports it.
- D. At a toll plaza. — Toll plazas are not mentioned anywhere in the passages as a reason to leave a bigger gap when stopped.
Remember it
Picture a car parked uphill on a hill: it can slip backward before it goes forward, so hang back farther.
