Driving laws change often. Staying current helps protect your safety and your legal rights. Several Arizona traffic laws 2026 updates and proposals affect drivers across Arizona. Below is a clear guide explaining what is currently enforceable and what may change soon.
Revised Speed Enforcement Rules – Arizona Revised Statutes §28-1203
Arizona permits automated traffic enforcement systems under specific conditions. State law restricts placement near speed limit changes and regulates how citations are issued. These systems monitor speeding and red light violations.
Updated HOV Lane Restrictions
As of Wednesday, October 1, 2025, electric vehicles and other alternative fuel vehicles with only a driver will no longer be allowed in HOV lanes during restricted times unless federal law changes. HOV lanes in the Phoenix area require two or more occupants on weekdays from 6 a.m. to 9 a.m. and 3 p.m. to 7 p.m. Exempt vehicles include motorcycles, public transit buses, emergency vehicles, and tow trucks performing official duties.
Alternative fuel vehicles previously qualified under a federal provision [23 USC 166(b)(4)], including those running on electricity, natural gas, propane, hydrogen, or biofuels, but that exemption has lapsed. State troopers may enforce violations with discretion, considering safety and context. Drivers can find more information at ADOT HOV Resource.
Left Lane Driving Rules Proposal – House Bill 2235 (HB 2235)
Lawmakers have proposed stricter enforcement for drivers who remain in the left lane while traveling slower than surrounding traffic. The proposal, House Bill 2235, would require signs reading “Left lane for passing only, slow traffic keep right” and establish a civil penalty for violations. This measure is still under review and is not yet law.
Proposed Pet Distraction Law – Senate Bill 1270
A pending bill, Senate Bill 1270, would fine drivers who operate a vehicle with a pet on their lap. Lawmakers note pets can distract drivers in a manner similar to handheld devices. This measure has not yet been enacted.
