Arizona motorcycle laws: lane filtering, helmets and more

This page explains Arizona motorcycle laws in plain English so riders know what to look up. It is not legal advice and it may not cover every condition or exception. Laws change. Before you rely on any rule here, read the statute itself on the Arizona Legislature's site, linked below, and talk to a lawyer if you have a specific situation.

What it does not allow: splitting lanes between moving traffic, and filtering on freeways, where the speed limit is above 45 mph. Read A.R.S. 28-903 for the exact wording, including any conditions we haven't listed.

Even when it's legal, drivers may not expect it, especially visitors from states where filtering isn't allowed. Go slowly, watch for doors and lane changes, and be ready to stop when the light changes. In summer heat, filtering up at a light can mean less idling in the sun, which is easier on you and on an air-cooled engine.

Arizona requires riders and passengers under 18 to wear a protective helmet. Riders 18 and over are not required to by that statute. The same statute also covers eye protection, such as glasses, goggles or a face shield, when the motorcycle doesn't have a windshield. Read A.R.S. 28-964 for the exact rules.

Not required isn't the same as a good idea. A helmet also cuts wind noise, keeps the sun off your face in the desert, and stops a monsoon downpour or a bug at speed from becoming a problem.

In Arizona, you need a motorcycle endorsement (Class M) to ride on public roads. It is issued by ADOT's Motor Vehicle Division. Taking an approved motorcycle safety course is the common path, and completing one can let you skip the riding skills test at MVD. Check ADOT MVD for the current steps, since requirements can change.

A safety course is worth it even if you're already licensed. Arizona riding asks a lot: heat, gravel in corners, wildlife on high-country roads, and wind in the open desert. If you're new to riding, see our page on the motorcycle app for beginners.

Arizona has a hands-free law for drivers that bars holding a phone while driving, with exceptions for hands-free and mounted use. Check ADOT or the law itself for the details. On a bike, the simple rule is: don't touch the phone while you're moving.

Rippin' is built for that. Tap Record Ride once before you roll, pocket the phone or mount it, and ride. Recording runs in the background, and you tap Stop at the end. Set up turn-by-turn on a loop builder route before you leave, and pull over to change anything.

Carry your license with the motorcycle endorsement, your registration and proof of insurance. Arizona requires liability insurance on registered vehicles. Check ADOT MVD for the current minimums, since they can change.

Riding in a group doesn't change the rules for any one rider: each bike follows the same traffic laws. Ride staggered on open roads, single file in the twisties, and regroup at stops instead of running lights to keep up. A group ride in Rippin' puts everyone on one live map, so nobody has to rush to stay in sight.

Segments in Rippin' are stretches of road a rider added. Ride through one and you're timed automatically, but the board is about who owns the road and who rides it, not a race. Rippin' does not reward speed on public roads. Turf, poker cards and points all come from riding, not from riding fast.

Popular roads like Mt Lemmon, the Bush Highway, the Beeline and Oak Creek Canyon can see enforcement. Ride them at a pace that leaves margin, and save the fast laps for a track day.

Privacy matters too. Set a home privacy safe zone so the part of your rides near home stays hidden from other riders. Live location is only shared when you start a group ride or broadcast.
