What is true of work zones?
- They are always stationary and therefore easily avoided
- They are only dangerous at night
- Speeding fines are tripled when workers are present
- Rear-end collisions are the most common type of crash in work zones ✓
Answer: D. Rear-end collisions are the most common type of crash in work zones
The true statement is that rear-end collisions are the most common type of crash in work zones.
Why this is the answer
The manual names the rear-end crash as the most frequent collision in a work zone. It then tells you to avoid that crash by leaving at least two seconds of braking distance from the vehicle ahead. That supports the statement about rear-end collisions being most common. The same section also warns that work zones are not always fixed in place, so the choices claiming they are always stationary or only dangerous at night do not fit. It does not mention tripled speeding fines when workers are present.
Why the other answers are wrong
- A. They are always stationary and therefore easily avoided — The manual says some work zones are not stationary, such as line painting, patching, or mowing, so they are not always fixed and easily avoided.
- B. They are only dangerous at night — The passages do not say work zones are dangerous only at night; they describe them as places requiring caution and reduced speed without limiting the danger to nighttime.
- C. Speeding fines are tripled when workers are present — The passages do not mention tripled speeding fines when workers are present, so that specific penalty is not supported by the handbook text.
Remember it
Picture a work zone as a place to back off: keep a two-second gap so you do not become part of the most common work-zone crash.
