You may pass a vehicle when:
- You are on a hill or curve.
- You are on a road with a solid line next to your lane.
- You are on a road with a broken line next to your lane. ✓
Answer: C. You are on a road with a broken line next to your lane.
You may pass a vehicle when the line next to your lane is a broken line, as long as you can do it safely without interfering with traffic.
Why this is the answer
The manual explains what the lines between lanes mean. A single broken line means you can pass other vehicles or change lanes, provided you do it safely and do not get in the way of traffic. The same idea applies when a solid and a broken line run together: the side with the broken line is the side that may pass. So a broken line next to your lane is the marking that gives you permission to pass.
Why the other answers are wrong
- A. You are on a hill or curve. — Being on a hill or a curve is not what the manual's line-marking rules use to decide whether passing is allowed, so this does not by itself give you permission to pass.
- B. You are on a road with a solid line next to your lane. — When the line next to you is solid, the manual says you cannot pass other vehicles or cross that line, except to turn left into a driveway.
Remember it
Read the line on your own side of the road: broken means passing is allowed, solid means it is not.
