Massachusetts Fines and Limits Permit Practice Test

On a multilane roadway with several lanes in one direction, which lanes should you use for passing?

1. Right lane

2. Middle or left lanes

3. Any lane

4. Shoulder lane

The correct answer is: Middle or left lanes

The reasoning behind using the middle or left lanes for passing on a multilane roadway stems from the established traffic conventions and safety principles. In most road systems, especially on highways and multi-lane roads, the left lanes are designated as passing lanes. This allows for smoother traffic flow and minimizes the risk of accidents since vehicles can overtake slower traffic without merging in front of those who are already in the rightmost lane, where slower vehicles typically remain. The use of the left or middle lanes for passing also aligns with the idea of maintaining a clear and organized roadway. By utilizing these lanes for faster-moving traffic to overtake, it helps reduce congestion in the right lanes, which are primarily reserved for vehicles traveling at lower speeds or preparing to exit. While it is technically possible to pass in any lane, doing so from the right can create confusion and unsafe situations, as it is less expected and can catch drivers off guard. Additionally, using the shoulder lane for passing is not advisable as it is often not intended for travel and can create hazards, such as collisions with vehicles that are entering or exiting the roadway.
