Arizona Now Treats Illegal Motorcycle Lane Filtering as Reckless Driving

Arizona now treats passing a vehicle while staying in that vehicle’s lane and riding between traffic lanes or adjacent rows as reckless driving. House Bill 2941 took effect September 12, 2026. The law keeps a limited exception for passing stopped traffic at low speed.

Arizona’s driver manual calls the permitted stopped-traffic maneuver lane filtering: a rider on a two-wheeled motorcycle moves between lanes to pass a vehicle stopped in the rider’s lane and headed in the same direction.

The street must have at least two adjacent same-direction lanes and a posted limit of 45 mph or less. The rider must travel at 15 mph or less and pass safely.

A proven violation of one of the cited lane rules can lead to a reckless-driving conviction, ordinarily a class 2 misdemeanor. A citation is an allegation; the facts of the maneuver and the stopped-traffic exception matter.

What HB 2941 changed on September 12

The enacted HB 2941, Chapter 261, added subsection B to Arizona’s reckless-driving statute, A.R.S. § 28-693. It directly classifies a motorcycle violation of either of these existing lane rules as reckless driving:

1. Passing within a lane — § 28-903(B): A rider generally may not overtake another vehicle while staying in the lane that vehicle occupies.
2. Riding between lanes or rows — § 28-903(C): A rider generally may not operate between traffic lanes or adjacent rows of vehicles.

The first rule covers overtaking a car while the motorcycle stays beside it in the car’s lane, rather than moving into another lane. The second covers riding in the gap between lanes or adjacent rows, even when the rider is not passing a particular car.

Both rules retain the stopped-traffic exception in § 28-903(F). When that exception applies, the maneuver is authorized; otherwise, a charge under the new subsection still depends on proving what the rider did.

The new subsection does not require a collision. A rider can face the charge after a prohibited same-lane pass or between-lanes maneuver even when no vehicle was struck; the underlying lane violation still has to be established.

The Legislature’s 2026 session summary lists September 12 as the effective date, following the bill’s June approval.

Arizona’s lane-filtering exception still has five checks

The exception in A.R.S. § 28-903(F) allows lane filtering only when all five of these checks are satisfied:

1. Stopped vehicle: The vehicle being passed is stopped in the rider’s lane and headed in the same direction. The exception is not a general right to pass moving traffic between lanes.
2. Two-wheel motorcycle: The wording is limited to a two-wheeled motorcycle; do not assume a trike receives the same exception.
3. Street layout: The street has at least two adjacent traffic lanes moving in the same direction.
4. Posted limit: The street’s speed limit is 45 mph or less.
5. Motorcycle speed and safety: The rider travels 15 mph or less, and the movement can be made safely.

A rider traveling at 12 mph on a 50-mph road still fails the posted-limit check. On a 35-mph street, a rider going 20 mph exceeds the motorcycle-speed limit. The vehicle being passed must actually be stopped; slow-moving traffic does not meet that condition.

A shoulder or a street with just one same-direction lane does not meet the two-adjacent-lanes requirement. Turn lanes near an intersection can make the layout less obvious; the rider must establish that the street meets the statute before using the exception.

The pass must also be safe even when both speed limits fit. A gap can close, a door can open or a driver can change position, so a rider should abandon a pass that no longer has room.

What a citation or conviction can mean

The current A.R.S. § 28-693 separates an allegation from the penalties that follow a conviction:

1. Citation: An officer’s allegation does not establish that the rider violated § 28-903(B) or (C). The stopped vehicle, lane layout, posted limit, rider speed, safe gap and any video or witness evidence may matter.
2. Conviction without a qualifying prior: Reckless driving is ordinarily a class 2 misdemeanor. A judge may suspend driving privileges for up to 90 days and must report the conviction to the Arizona Department of Transportation; the suspension is not automatic.
3. Specified prior conviction: A qualifying prior offense within 24 months can make the new conviction a class 1 misdemeanor, with a statutory minimum of 20 days in jail before release eligibility and a one-year suspension. The prior offense must be one listed in § 28-693(E), not just any old ticket.

The listed priors include earlier reckless driving and certain DUI offenses; an unrelated parking or equipment citation does not qualify. Section 28-693(G) measures the 24 months by the dates the offenses were committed, which may differ from the court dates.

If cited, preserve the citation and any available video, and seek qualified Arizona legal advice about the actual facts of the case.

A red light is not enough by itself

A line of cars stopped at a red light can present the situation § 28-903(F) covers. The red light itself does not waive the lane-layout, posted-limit, motorcycle-speed or safety checks. If the cars begin moving, the stopped-vehicle condition may no longer apply to a continued pass.

Section 28-903 also gives a motorcycle the full use of a lane, limits riding abreast to two motorcycles, and exempts peace officers performing official duties from the passing restrictions. Those separate rules do not expand lane-filtering permission for other riders.

What this changes for an Arizona rider

HB 2941 amends the reckless-driving statute; Arizona’s motorcycle insurance minimums are unchanged by this bill. Coverage or rates after a collision depend on the claim and policy, so this traffic-law change alone does not answer an insurance question.

Before using the stopped-traffic exception, check the posted limit and lane layout. A 40-mph street with two same-direction lanes presents a different question from a 55-mph road or a one-lane street. In a group with trikes, remember that the exception covers two-wheeled motorcycles.

If the vehicles are moving or the gap is unsafe, remain in the normal lane. Arizona still permits limited lane filtering past a stopped vehicle, while a proven violation of § 28-903(B) or (C) now falls under the reckless-driving law.
