This sign means?
- Road forks to the right.
- This is a pedestrian crossover
- The lane is only for two-way left turns.
- Keep to the right lane except when passing on two-lane sections where climbing or passing lanes are provided ✓
Answer: D. Keep to the right lane except when passing on two-lane sections where climbing or passing lanes are provided
That sign tells you to keep to the right lane except when passing on two-lane sections where climbing or passing lanes are provided.
Why this is the answer
The handbook lists this sign among the common regulatory signs and gives its meaning in the same list: stay in the right lane, and only move left to pass on a two-lane road that has a climbing or passing lane. The passing and climbing lane section explains the point of those lanes — slower vehicles move right so faster traffic can pass safely on the left — which fits the instruction to hold the right lane and use the passing lane only for passing.
Why the other answers are wrong
- A. Road forks to the right. — The handbook lists the sign meaning the road forks to the right as a separate sign, not this one.
- B. This is a pedestrian crossover — A sign saying this is a pedestrian crossover, where you must be ready to stop and yield to pedestrians, is listed separately from this lane sign.
- C. The lane is only for two-way left turns. — The sign showing that a lane is only for two-way left turns, placed above the road or painted on it, is a different sign in the same list.
Remember it
Think of it as a lane-keeping rule: stay right, and treat the left lane as borrowed space for passing.
