When a traffic light turns yellow, what is the driver advised to do?
- Continue driving at the same speed
- Stop if it's safe to do so ✓
- Immediately hit the brakes
- Speed up to cross before it turns red
Answer: B. Stop if it's safe to do so
When the light turns yellow, you should stop if it is safe to do so.
Why this is the answer
The truck handbook says a yellow or amber signal means red is about to appear. The instruction is to stop when you can do so safely; if you cannot, you should continue with caution. That matches stopping only when it is safe, rather than treating every yellow light the same. The handbook does not tell you to keep your speed, brake immediately, or speed up to beat the red.
Why the other answers are wrong
- A. Continue driving at the same speed — Continuing at the same speed ignores the handbook's instruction to stop when stopping is safe, so it is not the advised response.
- C. Immediately hit the brakes — Hitting the brakes immediately is too absolute; the handbook ties stopping to whether you can do it safely.
- D. Speed up to cross before it turns red — Speeding up to cross before red is not what the handbook says; it says stop if safe, otherwise go with caution.
Remember it
Treat amber as a question, not a command to speed up: can I stop safely?
