Lane Splitting and Filtering: Is it Legal In Utah?

When it comes to motorcycles, Utah riders often seek clarity on the legality of lane splitting and filtering. These terms refer to the practice of riding a motorcycle between lanes or stopped or slow-moving traffic. While some states have strict regulations or outright bans, Utah’s stance on lane splitting and filtering is very nuanced. In this article, we will explore the legal landscape surrounding these practices in the state of Utah, providing valuable insights for motorcycle enthusiasts and motorists alike.

Lane Splitting Vs. Filtering: Definitions and Distinctions

Lane splitting involves riding a motorcycle between lanes of either moving or stopped traffic on a highway, often during slow or stopped traffic. Filtering, on the other hand, refers to a motorcycle moving between lanes of stationary or slow-moving vehicles to reach the front of the traffic queue at a traffic signal.

Utah’s Lane Splitting and Filtering Laws

In the state of Utah lane filtering is legal, however there are a few caveats to this law. As of May 2019 Utah state legislature passed a bill allowing lane filtering by motorcycles. this means that as a motorcyclist you are allowed to drive in between lanes up to a traffic signal, or while traffic is stopped. Lane filtering in Utah is only allowed on stretches of road where the posted speed limit is 45 miles per hour or less, meaning that it is illegal to lane split or filter on any Utah highway where the speed limit is higher than 45. Lane filtering is also only allowed on roads with two or more lanes of traffic moving in the same direction, lane splitting is also only legal if your motorcycle is traveling at speeds 15 miles per hour and under.
