On a multi-lane highway, slower traffic should operate in which lane?

• A. The left lane
• B. The right lane
• C. The center lane
• D. The shoulder

Answer: (B)

The main idea is to keep slower traffic in the right-hand lane to let faster vehicles pass safely and keep traffic flowing smoothly. When you’re moving slower than surrounding cars, use the right lane and stay there as much as possible, signaling and checking for gaps before merging back if you need to pass or exit. The left lane is typically used by faster traffic for passing, so cruising there can disrupt flow and lead to more weaving and close-passing risks. The center lane isn’t designated specifically for slow driving, and the shoulder is only for emergencies, not normal travel. Following the practice of staying to the right when slow helps reduce conflicts and keeps everyone moving more safely.
