Yes, Lane splitting is legal in Arizona under ARS §28-921(A), effective since September 23, 2022. The statute permits motorcyclists to pass between lanes of traffic, provided they do so at speeds no greater than 15 mph above adjacent traffic and under safe conditions. The Arizona Department of Transportation (ADOT) enforces compliance, while local law enforcement agencies, such as the Phoenix Police Department, issue citations for violations like excessive speed or reckless maneuvering.
Key Regulations for Lane Splitting in Arizona
