New Arizona Law Reclassifies Motorcycle Lane Splitting as Reckless Driving

Arizona motorcyclists face steeper consequences for lane splitting under a new state law that took effect in mid-September 2026.

House Bill 2941, sponsored by Rep. Lupe Contreras and signed into law on June 22, 2026, reclassifies lane splitting — riding a motorcycle between lanes of moving traffic — as reckless driving. The maneuver was already illegal in Arizona, but violations had not previously been treated as reckless driving.

The change carries criminal consequences. Reckless driving is a class 2 misdemeanor in Arizona. Under the new classification, a judge can order a convicted rider to surrender their license, the conviction must be reported to the Arizona Department of Transportation, and ADOT can suspend driving privileges for up to 90 days.

Penalties escalate for repeat offenses. A driver convicted of reckless driving who has a prior reckless driving conviction within the previous 24 months faces a class 1 misdemeanor, cannot receive probation, a pardon, or a suspended sentence until serving at least 20 days in jail, and faces a one-year suspension of driving privileges.

The new law does not affect lane filtering, a separate maneuver Arizona legalized in 2022 that remains legal today. Lane filtering permits a motorcyclist to move between fully stopped vehicles — for example, at a red light — but only on roads with a posted speed limit of 45 mph or less that have two or more adjacent lanes, at speeds no greater than 15 mph, and never on a freeway. Lane filtering was designed to protect riders from being rear-ended while stopped in traffic.

The two maneuvers are often confused because they look similar, but Arizona law now treats them very differently: one remains legal in a narrow set of conditions, while the other now carries criminal exposure.
