The bill amends Chapter 31-15 of the General Laws, introducing a new section titled "Lane filtering for motorcycles - definition." This section defines "lane filtering" as the act of a two-wheeled motorcycle operator overtaking and passing another vehicle that is either stopped or traveling at a speed not exceeding ten miles per hour (10 mph) in the same direction and lane. The bill stipulates that lane filtering is permissible under specific conditions: the road must have lanes wide enough for safe passage, the motorcycle must not exceed a speed of twenty miles per hour (20 mph) while overtaking, and the conditions must allow for reasonable and prudent operation of the motorcycle.

The act aims to enhance the safety and efficiency of motorcycle operation in traffic by allowing riders to navigate through congested areas more effectively. It is set to take effect immediately upon passage, promoting safer practices for motorcyclists in situations where they encounter stopped or slow-moving vehicles.
