On a three-lane highway, which vehicles should generally avoid using the left lane?

• A. Slower vehicles
• B. Faster vehicles
• C. Motorcycles
• D. Emergency vehicles

Answer: (D)

The left lane on a three-lane highway is reserved mostly for passing slower traffic. When you’re moving more slowly than the surrounding flow, you should stay in the right-hand lanes and let faster traffic pass in the left lane. This keeps traffic moving smoothly and reduces weaving or sudden lane changes. If you’re driving slower than other cars, move to the right as soon as it’s safe so others can pass. Faster vehicles belong in the left lane to pass, not stay there continuously. Motorcycles can use any lane, but they aren’t the standard rule about left-lane usage. Emergency vehicles have priority and may use any lane as needed; drivers should yield to them, but the general rule about regular traffic is about keeping the left lane clear for passing.
