Arizona law prohibits lane-splitting, or riding between rows of slowed or stopped traffic. Motorcycles can only share the same lane with other motorcycles as long as the number of motorcycles that ride side-by-side does not exceed two. Even though lane-splitting is not legal in Arizona, many riders pass vehicles using the same lane, especially on congested Phoenix roads during rush hour. If you were in a lane-splitting accident, contact a Phoenix motorcycle accident lawyer to help you determine fault and explore your options for compensation.
