Arizona’s New Motorcycle Lane-Splitting Law: Violating A.R.S. § 28-903 Is Now Automatic Reckless Driving
Arizona has just changed how it treats motorcyclists who split lanes or pass improperly. Under 2026 Chapter 261 (House Bill 2941), signed by the Governor on June 22, 2026, a motorcycle rider who violates A.R.S. § 28-903, subsection B or C is now automatically guilty of reckless driving — a criminal misdemeanor, not just a traffic ticket. The law takes effect September 12, 2026.
If you ride in the Phoenix metro area, or if you’ve been cited for a motorcycle traffic violation, here is exactly what changed, why it matters, and what it could mean for your record.
What This Means for You
- Lane-splitting and improper passing are no longer “just a ticket.” Starting September 12, 2026, a violation of A.R.S. § 28-903(B) (passing in the same lane as the vehicle you’re overtaking) or § 28-903(C) (riding between lanes of traffic) is charged as reckless driving under A.R.S. § 28-693 — a class 2 misdemeanor with up to 4 months in jail.
- A conviction is a permanent criminal record, not a civil traffic infraction, and can carry a driver’s license suspension of up to 90 days at the judge’s discretion.
- Repeat violations escalate quickly. A second qualifying offense within 24 months becomes a class 1 misdemeanor with a mandatory minimum 20 days in jail and a mandatory one-year license suspension.
- There is still a legal way to filter through slow or stopped traffic — the narrow exception in § 28-903(F) — but it only applies under specific speed, lane-count, and safety conditions explained below.
- If you’re cited or arrested, don’t assume it’s a minor matter. Because this is now a reckless driving charge, it deserves the same serious defense review as any other misdemeanor.
What the New Law Actually Says
HB 2941 amends A.R.S. § 28-693 (Reckless Driving) by adding a new subsection B:
“A person who operates a motorcycle in violation of section 28-903, subsection B or C is guilty of reckless driving.”
Previously, § 28-693 defined reckless driving only in general terms — “a person who drives a vehicle in reckless disregard for the safety of persons or property.” Prosecutors had to prove that broad, subjective standard. The new law removes that ambiguity for motorcyclists: proving a violation of § 28-903(B) or (C) is now, by itself, enough to sustain a reckless driving charge.
Understanding A.R.S. § 28-903: The Rules That Now Trigger a Reckless Driving Charge
A.R.S. § 28-903 governs how motorcycles may operate on laned roadways. Here is what each relevant subsection actually requires:
Subsection A — Full Lane Use
Motorcycles are entitled to full use of a traffic lane, and other drivers may not deprive a motorcycle of that full lane. Two motorcycles may lawfully ride side by side (“two abreast”) within a single lane — this is unaffected by the new law.
Subsection B — No Passing Within the Same Lane (Now Triggers Reckless Driving)
A motorcyclist may not overtake and pass another vehicle while remaining in the same lane that vehicle occupies.
Subsection C — No Riding Between Lanes (Now Triggers Reckless Driving)
A motorcyclist may not operate between lanes of traffic or between adjacent rows of vehicles — commonly known as “lane splitting.”
Subsection D — Maximum Two Abreast
No more than two motorcycles may ride side by side in a single lane. This subsection is not among those that trigger the new reckless driving provision.
Subsection E — Peace Officer Exception
Subsections B and C do not apply to peace officers performing official duties.
Subsection F — The Narrow “Lane Filtering” Exception
This is the one exception riders most need to understand, because it defines the legal boundary of the new reckless driving law. A two-wheeled motorcycle may pass a vehicle stopped in the same lane, or travel between lanes, only if all of the following are true:
- The movement can be made safely;
- The street has at least two adjacent lanes traveling the same direction;
- The posted speed limit on that street is 45 mph or less; and
- The rider does not exceed 15 mph while filtering.
Ride outside these four conditions — on a highway with a higher speed limit, at more than 15 mph while filtering, or between lanes of moving (not stopped) traffic — and the conduct falls back under subsections B or C, which as of September 12, 2026, means an automatic reckless driving charge.
Penalties: What a Reckless Driving Conviction Now Means for a Motorcyclist
| Circumstance | Classification | Potential Penalty |
|---|---|---|
| First offense | Class 2 misdemeanor | Up to 4 months jail, fines/surcharges up to roughly $750, possible license suspension up to 90 days |
| Second qualifying offense within 24 months* | Class 1 misdemeanor | Mandatory minimum 20 days in jail before eligibility for probation or early release; mandatory 1-year license suspension |
| Aiding or abetting another person’s violation | Class 2 misdemeanor (Class 1 if repeat) | Same tiered penalties apply to a person who knowingly helps another commit the violation |
*Qualifying priors include a prior reckless driving conviction, aggravated assault with a vehicle (A.R.S. § 13-1103(A)(1)), or certain DUI convictions under A.R.S. §§ 28-1381, 28-1382, or 28-1383 within the preceding 24 months.
In addition, a judge may order the surrender of the person’s driver’s license and must report any conviction to the Arizona Department of Transportation Motor Vehicle Division.
Why This Change Matters
Before this law, a lane-splitting citation was generally treated as a straightforward civil traffic violation — a fine, and often nothing more. Now, the same conduct can result in a criminal misdemeanor conviction that appears on a background check, may affect employment or professional licensing, and carries the possibility of jail time and license suspension. For riders who regularly commute through Phoenix-area traffic, the line between “convenient lane filtering” and “criminal reckless driving” has narrowed considerably — and it now depends on technical details like posted speed limits, lane counts, and exact speed while filtering.
How a Criminal Defense Attorney Can Help
Gordon Thompson has practiced criminal and DUI defense in Arizona for 47 years and has represented more than 6,000 clients in Municipal and Justice Courts throughout Maricopa County, Pinal County, and select Northern Arizona courts. If you’re cited or arrested for reckless driving arising from a motorcycle lane-splitting or passing violation, an attorney can evaluate:
- Whether the initial traffic stop was lawful;
- Whether the officer’s report and any dash or body camera video actually establish every element of § 28-903(B) or (C);
- Whether the § 28-903(F) safe-filtering exception applies to your specific speed, lane configuration, and conditions;
- Whether the charge can be resolved through dismissal, a reduced charge, or trial.

Frequently Asked Questions
What does Arizona’s new motorcycle reckless driving law do?
Arizona’s 2026 Chapter 261 (House Bill 2941) amends A.R.S. § 28-693 so that any motorcyclist who violates A.R.S. § 28-903(B) or (C) — the laws against overtaking in the same lane or riding between lanes of traffic — is automatically guilty of reckless driving. Before this law, those violations were typically charged as ordinary traffic infractions. Reckless driving is a class 2 misdemeanor carrying up to 4 months in jail, up to a $750 fine, and a possible 90-day license suspension.
Is lane splitting illegal in Arizona?
Yes, in most circumstances. A.R.S. § 28-903(C) prohibits operating a motorcycle between lanes of traffic or between adjacent rows of vehicles. There is a narrow exception under subsection F that allows a two-wheeled motorcycle to filter between stopped or slow lanes only if the road has at least two adjacent lanes going the same direction, the posted speed limit is 45 mph or less, the rider does not exceed 15 mph, and the movement can be made safely. Riding between moving traffic outside that exception is illegal, and as of September 12, 2026, it is also automatically reckless driving.
When does the new Arizona reckless driving law take effect?
Chapter 261 (HB 2941) was signed by the Governor on June 22, 2026. Because the bill does not contain an emergency clause, it takes effect on Arizona’s general effective date for the 2026 legislative session, which is September 12, 2026 — 90 days after the Legislature adjourned sine die.
What are the penalties for reckless driving in Arizona under this new law?
A first violation is a class 2 misdemeanor, punishable by up to 4 months in jail, a fine of up to $750 plus surcharges, and possible license suspension of up to 90 days at the judge’s discretion. If the person has a qualifying prior conviction (reckless driving, aggravated assault with a vehicle, or certain DUI offenses) within the previous 24 months, the charge becomes a class 1 misdemeanor with a mandatory minimum of 20 days in jail before eligibility for probation, pardon, or early release, plus a mandatory one-year license suspension.
Can passing a stopped vehicle on a motorcycle still be legal in Arizona?
Yes, under the narrow exception in A.R.S. § 28-903(F). A two-wheeled motorcycle may overtake and pass a vehicle that is stopped in the same lane and direction of travel, and may travel between lanes, only if: (1) the street has at least two adjacent lanes in the same direction with a posted speed limit of 45 mph or less, (2) the rider does not exceed 15 mph, and (3) the movement can be made safely. This exception does not apply to riding between moving traffic.
Does this new law apply to riding two abreast in the same lane?
No. A.R.S. § 28-903 permits up to two motorcycles to ride side by side within a single lane, and this practice is not affected by the new reckless driving provision, which applies only to violations of subsections (B) overtaking in the same lane as the vehicle being passed and (C) riding between lanes of traffic.
What should I do if I’m charged with reckless driving on a motorcycle in Arizona?
Do not plead guilty at an arraignment before speaking with a criminal defense attorney. Because a reckless driving conviction is now a permanent criminal misdemeanor (not just a traffic ticket) and can lead to license suspension, jail time, and a criminal record, it is worth having an attorney review whether the stop was lawful, whether the officer can establish the specific elements of A.R.S. § 28-903(B) or (C), and whether the safe-passing exception in subsection F applies to your situation.
