Motorcycle riders across Arizona often ask the question: “Is lane splitting legal in Arizona?” At Jensen Phelan Law Firm, we hear this concern from riders trying to move safely through traffic while avoiding legal trouble.
Under Arizona traffic laws, lane splitting and lane filtering are treated very differently, and many riders only discover this distinction after a collision. The difference between these terms raises questions about fault and insurance coverage.
Understanding how Arizona defines these riding practices helps motorcyclists make informed decisions on the road and places injured riders in a stronger position when liability disputes arise.

No, lane splitting is not allowed under Arizona traffic law. Riding a motorcycle between lanes of moving vehicles violates state statutes and often becomes a central factor in determining liability following a motor vehicle accident where lane splitting occurred.
Arizona Revised Statutes § 28-903 governs how motorcycles may operate on laned roadways. This law confirms that motorcycles are entitled to full use of a traffic lane while also restricting how riders may pass other vehicles. It prohibits overtaking and passing another vehicle within the same lane and bars motorcycles from operating between lanes of traffic or between adjacent rows of vehicles, except in very specific situations unrelated to traditional lane splitting.
This framework extends beyond traffic citations. After a collision, insurance companies frequently argue that unlawful lane splitting caused or contributed to the crash. Riders often raise questions about Arizona’s lane-splitting rules after seeing how quickly a false allegation can threaten an injury claim.
Under Arizona Revised Statutes § 28-903, lane filtering law is permitted, allowing for limited movement of motorcycles between vehicles under specific conditions. Lane filtering, as opposed to lane splitting, occurs when surrounding traffic is completely stopped, such as at red lights or congested intersections, and only when the motorcycle is moving at a low speed relative to nearby vehicles. Lane filtering can only occur on roads where the speed limit is 45mph or less. The motorcyclist cannot exceed a speed of 15mph, or their actions are no longer considered lane filtering.
Lane filtering is distinctly different from lane splitting. Filtering occurs around stopped vehicles under specific traffic conditions, while splitting occurs in moving traffic.
Even when a rider follows filtering rules, drivers and insurers sometimes misunderstand the law. After a collision, adjusters may argue that traffic had already started moving or claim the motorcycle was traveling too fast. Riders who understand Arizona’s lane-filtering framework are better positioned to challenge misplaced blame.
Several legal and practical differences separate these two riding practices, especially once a motor vehicle accident triggers a liability review:
These distinctions help answer “Is lane splitting legal in Arizona?” in practical terms, particularly when a crash leads to contested responsibility.
Fault after a motorcycle collision rarely follows a simple formula. Arizona follows a comparative negligence system, which means more than one party may share responsibility for a crash.
Arizona Revised Statutes § 12-2505 explains how comparative negligence works in injury cases. Under this law, a claimant’s recovery does not disappear simply because some fault exists. Instead, damages may be reduced in proportion to the claimant’s degree of responsibility, unless the injured person intentionally or recklessly caused the harm.
When lane filtering plays a role in a motorcycle accident, insurers and investigators commonly examine several factors to assess fault:
These details often determine whether insurers treat the incident as lawful lane filtering or argue unlawful lane splitting.
