Utah lane filtering law

Lane filtering legal since May 1, 2024

Utah allows filtering past stopped vehicles at 15 mph or less, on roads with two or more lanes in the same direction and a speed limit of 45 mph or less, or on off-ramps. Since January 1, 2026, splitting through moving traffic has been its own offense, with a suspension of the motorcycle endorsement. The filtering permission is set to expire on July 1, 2027.
