The bill amends Chapter 31-15 of the General Laws, specifically addressing "Passing, Use of Lanes, and Rules of the Road," by adding a new section that permits lane splitting for motorcycles. Lane splitting is defined as the act of a motorcycle, with two wheels in contact with the ground, moving between rows of stopped or moving vehicles in the same lane. This practice is allowed under certain conditions: traffic must be stopped or moving at no more than 10 mph, the motorcycle cannot exceed 10 mph above the flow of traffic, the motorcycle must merge back with traffic once the flow reaches 10 mph, and the highway's posted speed limit must be over 50 mph. The bill also grants the administrator the authority to develop necessary rules and regulations in consultation with the department of public safety.

The bill includes a sunset clause, stating that the provisions authorizing lane splitting will cease on January 28, 2025. The act is set to take effect upon passage and will expire on January 31, 2025. The legislative council explains that the act is intended to permit the practice of lane-splitting by motorcycles until the specified sunset date.
