On a highway with at least three lanes in each direction, the rightmost lane is for traffic that is entering or exiting the highway or that is traveling slowly.

• A. Vehicles entering or exiting the highway
• B. Vehicles entering or exiting the highway and traveling slowly
• C. Vehicles traveling fast
• D. Vehicles using the left lane to pass

Answer: (B)

This tests lane use on multi-lane highways. The rightmost lane is kept for traffic that is entering or exiting the highway or traveling at slower speeds. Keeping slower and exiting/entry traffic in the right lane helps faster through-traffic stay in the left lanes, improving merging and safety. The description that includes both entering/exiting and traveling slowly best matches this rule. Why the other descriptions fit less well: one only mentions entering or exiting and misses the slower-traffic aspect, while the others focus on fast traffic or passing in the left lane, which doesn’t describe the rightmost lane. When driving, stay in the rightmost lanes unless you’re passing or preparing to exit.
