This sign means?
- Slow traffic on multi-lane roads must keep right ✓
- School crosswalk sign
- Caution school bus crossing
- X intersection for school vehicles
Answer: A. Slow traffic on multi-lane roads must keep right
It means slow traffic on roads with several lanes must keep right.
Why this is the answer
The handbook lists this as a common regulatory sign, and regulatory signs must be obeyed. Its keep-right section says to stay in the right-hand lane on multi-lane roads unless you are turning left or passing, especially if you are moving more slowly than other vehicles. That matches the sign's meaning: slower traffic stays in the right lane. Nothing in the passages links this sign to schools.
Why the other answers are wrong
- B. School crosswalk sign — The passages describe a school zone warning sign that tells you to slow down and watch for children, but they do not describe a school crosswalk sign.
- C. Caution school bus crossing — There is no mention in the passages of a sign warning that a school bus may cross; the school-related sign covered is the school zone warning.
- D. X intersection for school vehicles — The X-shaped sign in the passages is a railway crossing warning, not a sign for an intersection used by school vehicles.
Remember it
Remember it by lane position: slower traffic stays right, while the left side is for passing or left turns.
