What is riding between lanes of traffic classified as?

Answer: B — Prohibited at all times

Riding between lanes of traffic is classified as prohibited at all times in Massachusetts. This practice, often referred to as lane splitting or filtering, is illegal as it poses significant safety risks. For motorcyclists, maneuvering between lanes of stopped or slow-moving vehicles can lead to accidents if a vehicle unexpectedly changes lanes or opens a door. In addition, prohibiting lane splitting helps to maintain predictable traffic patterns, allowing drivers and motorcyclists to anticipate one another's movements more effectively. Understanding this rule is crucial for the safety of both motorcyclists and other road users, ensuring that all adhere to established traffic laws designed to protect everyone on the road.
