On multilane roads, the middle lanes are generally used for

• A. The middle lanes usually offer the smoothest flow; left lane for passing; right lane for slower vehicles and exiting.
• B. The leftmost lane is for faster vehicles.
• C. The rightmost lane is for passing.
• D. The right lane is for trucks only.

Answer: (A)

On multilane roads, traffic flows most smoothly when drivers stay in the middle lanes for through travel, use the left lane for passing, and reserve the right lane for slower vehicles and entering/exiting. The middle lanes tend to have fewer disruptions from merging and ramp activity, so steady speeds can be maintained there. The left lane is kept clear for overtaking, with drivers expected to move back to a middle or right lane after passing. The right lane accommodates slower vehicles and provides a lane for entering and exiting, helping to prevent bottlenecks in the through lanes. This combination explains why the middle lanes are described as offering the smoothest flow, with the left for passing and the right for slower traffic and exits.
