When approaching a roundabout, you should always:
- Increase your speed.
- Decrease your speed. ✓
- Maintain your speed.
Answer: B. Decrease your speed.
When approaching a roundabout, you should decrease your speed.
Why this is the answer
The handbook's roundabout steps begin with slowing down as you approach. Only after slowing do you yield to traffic already circulating, wait for a big enough gap, and merge in to the right. Slowing first is what lets you check for traffic and enter safely, which is why the answer is to decrease your speed rather than hold or raise it.
Why the other answers are wrong
- A. Increase your speed. — Increasing your speed works against the handbook's first step, which is to slow down before you reach the roundabout.
- C. Maintain your speed. — Keeping the same speed skips the slowing step the handbook lists first, and you still need to yield and find a gap before entering.
Remember it
Picture the roundabout steps in order: slow down first, then yield, then pick your gap and go.
