Arizona motorcycle laws changed in 2026, making it more important than ever for riders to understand the difference between lane splitting and lane filtering.
As of September 12, 2026, certain violations involving motorcycle lane splitting can now constitute reckless driving in Arizona. However, Arizona still allows motorcycle lane filtering when specific requirements are met.
For riders throughout Phoenix, Scottsdale, Mesa, Chandler, Tempe, Glendale, Gilbert, and surrounding communities, understanding the Arizona lane splitting law can help prevent traffic violations and potentially dangerous motorcycle accidents.
If you were injured while riding, an experienced Phoenix motorcycle accident attorney at The Law Office of Zayed Al-Sayyed can review your accident and help you understand your legal options.
Is Lane Splitting Legal in Arizona?
Generally, lane splitting is not legal in Arizona outside the state’s specific lane-filtering exception.
Under A.R.S. § 28-903, a motorcycle operator generally may not overtake and pass another vehicle within the same occupied lane or operate between lanes of traffic or adjacent rows of vehicles.
Arizona law does, however, provide an important exception for qualifying lane filtering.
This distinction matters because lane splitting typically refers to a motorcyclist traveling between vehicles while surrounding traffic is moving, while Arizona’s lane-filtering exception applies to passing stopped vehicles under specific conditions.
What Changed With Arizona’s Motorcycle Lane Splitting Law in 2026?
Arizona lawmakers increased the potential consequences of illegal motorcycle lane splitting in 2026.
Under A.R.S. § 28-693, a motorcyclist who operates a motorcycle in violation of A.R.S. § 28-903(B) or (C) is guilty of reckless driving.
The change was enacted through HB 2941 and became effective September 12, 2026.
Previously, reckless driving generally required driving a vehicle with reckless disregard for the safety of people or property. The 2026 amendment expressly added qualifying motorcycle lane-use violations to Arizona’s reckless-driving statute.
This means illegally riding between lanes of moving vehicles is no longer something Arizona motorcyclists should view as simply a minor traffic matter.
Is Lane Filtering Legal in Arizona?
Yes. Lane filtering remains legal in Arizona when all statutory requirements are satisfied.
Arizona’s lane-filtering exception allows the operator of a two-wheeled motorcycle to pass a vehicle that is stopped in the same direction of travel and operate between lanes when the movement can be performed safely.
Arizona Lane Filtering Requirements
Under A.R.S. § 28-903, legal motorcycle lane filtering requires the following:
- The vehicle being passed must be stopped.
- The roadway must have at least two adjacent lanes traveling in the same direction.
- The posted speed limit cannot exceed 45 mph.
- The motorcycle cannot travel faster than 15 mph while filtering.
- The maneuver must be performed safely.
All of these requirements matter.
For example, traveling at only 10 mph between cars does not necessarily make the maneuver legal if those vehicles are moving or the roadway’s posted speed limit exceeds 45 mph.
Lane Filtering vs. Lane Splitting in Arizona
Motorcyclists sometimes use “lane filtering” and “lane splitting” interchangeably, but the distinction is critical under Arizona law.
What Is Lane Filtering?
Lane filtering generally involves a motorcycle slowly moving between lanes of stopped vehicles.
For example, imagine a motorcyclist approaching stopped traffic at a red light on a Phoenix road with a 40 mph speed limit and two lanes traveling in the same direction.
If the surrounding vehicles are stopped, the motorcyclist travels no faster than 15 mph, and the maneuver can be performed safely, it may qualify as legal lane filtering.
What Is Lane Splitting?
Lane splitting generally describes a motorcycle traveling between lanes or adjacent rows of vehicles while traffic is moving.
That distinction is especially important following Arizona’s 2026 law change because violating the applicable provisions of A.R.S. § 28-903 can constitute reckless driving.
Can Motorcycles Lane Filter at Red Lights in Arizona?
Potentially, yes.
A red light is one of the situations where Arizona’s lane-filtering law may apply because traffic is often completely stopped.
However, being at a red light does not automatically make filtering legal.
The road must still:
- Have at least two adjacent lanes traveling in the same direction
- Have a posted speed limit of 45 mph or less
The motorcycle must also remain at or below 15 mph, the vehicle being passed must be stopped, and the maneuver must be capable of being performed safely.
Can Motorcycles Lane Filter on Phoenix Freeways?
Arizona’s lane-filtering statute requires the street to have a posted speed limit of 45 mph or less.
Therefore, riders should not assume that stopped traffic on a Phoenix-area freeway makes lane filtering legal.
This is particularly relevant around heavily traveled Valley freeways such as I-10, I-17, Loop 101, and Loop 202, where congestion and stop-and-go traffic are common.
Even when freeway traffic comes to a complete stop, the roadway’s posted speed limit may prevent the maneuver from qualifying for Arizona’s lane-filtering exception.
What Are the Penalties for Illegal Lane Splitting in Arizona?
Arizona’s 2026 law significantly increases the potential consequences associated with prohibited motorcycle lane splitting.
A violation of the applicable motorcycle lane-use provisions can now constitute reckless driving.
Under A.R.S. § 28-693, a first reckless-driving conviction is a Class 2 misdemeanor.
The court may also require a convicted person’s driver’s license to be surrendered and may order driving privileges suspended for up to 90 days.
Repeat reckless-driving offenses within the statutory period can result in more serious consequences.
What Happens if a Motorcycle Accident Occurs While Lane Filtering?
Whether a motorcyclist was legally filtering can become an important issue after a Phoenix motorcycle accident.
Investigators, insurance companies, and attorneys may examine questions such as:
- Was surrounding traffic completely stopped?
- How fast was the motorcycle traveling?
- What was the posted speed limit?
- Did the roadway have at least two lanes traveling in the same direction?
- Was the motorcycle traveling between lanes?
- Did another driver unexpectedly change lanes?
- Did a driver open a vehicle door?
- Was the maneuver capable of being performed safely?
- Had traffic begun moving before the collision occurred?
Evidence such as traffic-camera footage, dashcam video, witness statements, police reports, vehicle damage, photographs, and electronic data may help establish what happened.
If you have been injured in this type of collision, speaking with a Phoenix motorcycle accident attorney can help you better understand how Arizona motorcycle laws may affect your claim.
Can a Motorcyclist Still Recover Compensation After an Accident?
A dispute over lane filtering does not automatically answer every question about liability in a motorcycle accident.
Arizona follows a pure comparative negligence system. Under A.R.S. § 12-2505, a person’s damages generally may be reduced in proportion to that person’s degree of fault.
For example, an investigation could examine the conduct of both the motorcyclist and another driver. A motorist who changes lanes without checking for surrounding traffic may raise different liability questions than a rider who was traveling between moving vehicles.
Because motorcycle crashes can involve conflicting accounts of what occurred, preserving evidence as quickly as possible can be important.
What Should Phoenix Drivers Know About Lane Filtering?
Arizona’s lane-filtering law applies to motorists as well as motorcyclists in practical terms.
Drivers may encounter motorcycles legally traveling between stopped vehicles on qualifying Phoenix streets.
Motorists should:
- Check mirrors and blind spots before changing lanes
- Signal before making a lane change
- Watch carefully for motorcycles at intersections
- Avoid intentionally blocking a motorcycle
- Leave adequate space between vehicles
- Avoid distracted driving
Motorcyclists should likewise remember that permission to lane filter is limited. The speed of traffic, posted speed limit, number of lanes, motorcycle speed, and safety of the maneuver all matter.
Arizona Motorcycle Safety
Motorcycle riders have substantially less physical protection than occupants of passenger vehicles, making safe driving practices especially important.
The National Highway Traffic Safety Administration’s motorcycle safety resources provide additional information about motorcycle visibility, helmets, safe riding practices, licensing, and sharing the road.
Arizona riders can also review current traffic statutes directly through the Arizona State Legislature, which publishes the Arizona Revised Statutes online.
