Arizona Lane Splitting vs Lane Filtering: HB 2941 and Reckless Driving Charges

Effective September 12, 2026 · House Bill 2941, Chapter 261 (signed June 22, 2026)

Disclaimer: This Guide is for general information only. It is not legal advice and does not create an attorney-client relationship. Arizona traffic and criminal laws turn on specific facts. If you were cited or charged for lane splitting, lane filtering, or reckless driving, talk with a licensed Arizona criminal defense lawyer about your situation.

Arizona lane splitting and lane filtering get mixed up in everyday talk, and after HB 2941, that mix-up can mean a reckless driving misdemeanor instead of a routine traffic ticket.

As of September 12, 2026, a motorcycle rider who violates A.R.S. § 28-903(B) or (C) (illegal same-lane passing or riding between lanes) is guilty of reckless driving under A.R.S. § 28-693. Arizona’s limited lane filtering rule in § 28-903(F) was not repealed. Filtering is still allowed only when every condition in that subsection is met.

Arizona lane filtering law (still legal if every condition is met)

Under A.R.S. § 28-903(F), a two-wheeled motorcycle operator may overtake a vehicle that is stopped in the same lane and direction of travel, and may operate between lanes of traffic, only if the move can be made safely and the rider does both of the following:

1. Operates on a street with at least two adjacent traffic lanes in the same direction and a speed limit of 45 mph or less; and

2. Travels at a speed of 15 mph or less.

If traffic is moving rather than stopped, the posted limit is higher than 45 mph, the rider is going faster than 15 mph, the road does not have two same-direction lanes, the motorcycle is not two-wheeled, or the move is not safe, the lane filtering exception generally does not apply.

Arizona lane splitting (not protected)

What most people mean by lane splitting in Arizona (weaving between moving cars, same-lane passing at speed, or riding between rows outside subsection (F)) remains barred by:

• § 28-903(B): a motorcycle operator shall not overtake and pass in the same lane occupied by the vehicle being overtaken (except as subsection F allows); and

• § 28-903(C): a person shall not operate a motorcycle between the lanes of traffic or between adjacent rows of vehicles (except as subsection F allows).

After HB 2941, a violation of (B) or (C) is charged as reckless driving.

Practical takeaway: slow, careful filtering next to stopped traffic on a low-speed multi-lane road may still fit the statute. Splitting through moving freeway or arterial traffic generally does not, and that is where the new reckless-driving exposure bites.

Reckless driving penalties for motorcycle lane violations

First offense under § 28-693 is a class 2 misdemeanor: up to four months in jail and a fine of up to $750 (A.R.S. §§ 13-707, 13-802), before surcharges. The court may also suspend driving privileges for up to 90 days and must report the conviction to the Arizona Department of Transportation.

Enhanced cases (certain prior convictions within 24 months, including prior reckless driving or other offenses listed in § 28-693) can become a class 1 misdemeanor, with a mandatory 20-day jail floor, higher jail and fine maxima, and a one-year license suspension by ADOT.

Outcomes depend on the charge, your record, and the facts of the stop.

If you were cited for lane splitting or reckless driving

A citation after September 12, 2026, may allege reckless driving based on claimed lane splitting. Whether legal lane filtering applies is often fact-specific: posted speed limit, stopped vs moving traffic, rider speed, lane layout, and any video.
