Arizona Driving Laws (2026): Speed Limits, Insurance and More

Arizona driving laws: speed limits

The maximum speed limit in Arizona is 75 mph. Rural interstates reach up to 75 mph and urban freeways up to 65 mph.

On busy roads such as I-10 and I-17, posted limits are frequently lower than 75 mph, especially through Phoenix and in work zones.

You must also keep a speed that is safe for rain, fog and traffic, even when that means going slower.

In short, under Arizona driving laws: max speed limit, 75 mph.

Arizona driving laws: cell phone and texting law

Only hands-free. Arizona enforces a hands-free law: drivers cannot hold a phone to make calls or send messages on the road. Voice calls through the car and a mounted map are fine.

Under the Arizona driving laws, a dash-mounted phone, spoken commands and one touch to take a call or start navigation stay legal; having it in your hand at a stoplight is what gets ticketed.

Young drivers get a stricter rule: in Arizona, permit and intermediate license holders (first 6 months or until 18) cannot use a phone in any way, not even through Bluetooth.

In short, under Arizona driving laws: phone law, hands-free law.

Arizona driving laws: driving age and teen licenses

Teens in Arizona can obtain a learner's permit at 15 and a provisional (intermediate) license at 16, which still restricts night driving and passengers.

Before the road test, permit holders in Arizona need 30 hours (not mandatory with driver education) of supervised driving.

Bottom line, under Arizona driving laws: learner's permit age, permit at 15.

Arizona driving laws: minimum car insurance

Arizona requires at least 25/50/15 in liability coverage: $25,000 for one injured person, $50,000 for all injuries in one crash and $15,000 for property damage.

Arizona uses fault-based claims, so the at-fault driver answers for the other parties' injuries and damage through liability coverage.

The legal minimum often falls short in a serious crash, since treatment and repairs can pass $50,000 fast.

Advisers frequently recommend a floor of 100/300/100, as damages above your limits can be taken from your savings.

In short, under Arizona driving laws: car insurance, 25/50/15.

Arizona driving laws: car sales tax

Arizona charges a 5.6% state transaction privilege tax on cars you buy, and local taxes can raise the total.

Arizona calls its sales tax a transaction privilege tax (TPT). Cities and counties add their own rates.

• A $18,200 car in Arizona: roughly $1,019 in state tax
• A $32,300 car in Arizona: roughly $1,809 in state tax
• A $55,000 car in Arizona: roughly $3,080 in state tax

A trade-in cuts the Arizona driving laws: a $30,000 car with a $5,000 trade-in owes roughly $1,400 rather than $1,680.

Bottom line, under Arizona driving laws: car sales tax, 5.6%.

Arizona driving laws: vehicle inspection and emissions

Only an emissions test. Arizona skips safety inspections, but does require emissions testing in the Phoenix and Tucson areas.

Since no safety inspection is mandatory in Arizona, maintaining brakes and tires in good order is up to the owner.

Smog checks on recent models scan the on-board computer, which takes a few minutes; a lit check-engine light generally means a failure.

In short, under Arizona driving laws: car inspection, emissions only.

Arizona driving laws: license and registration deadlines for newcomers

After moving to Arizona, you have right away, as soon as you become a resident to obtain a Arizona driver's license, and right away, as soon as you become a resident to register your car.

Arizona expects new residents to get an Arizona license and register their vehicles as soon as they become residents.

• Get a Arizona driver's license: Right away, as soon as you become a resident. Take proof of identity, your SSN and two proofs of address when you visit the Arizona MVD (REAL ID rules).
• Buy car insurance at or above the minimum: Arizona sets a floor of 25/50/15. A policy is generally mandatory before registration.
• Vehicle check: Only an emissions test. Arizona skips safety inspections, but does require emissions testing in the Phoenix and Tucson areas.

The clock typically begins when you take a job, sign a lease or register kids for school in Arizona, not on the day the boxes arrive.

In short, under Arizona driving laws: new resident deadline, right away.

Arizona driving laws: motorcycle helmet law

Only if you are under 18. In Arizona, motorcyclists 17 and younger must wear a helmet; adults 18 and older may legally ride without one. From Tucson to the capital, Phoenix, the same statewide rule applies.

Riders 17 and younger must wear a helmet under the Arizona driving laws; from age 18 a rider can decide.

Crash research suggests that helmets reduce over a third of rider deaths, and about 41% of passenger deaths.

A compliant helmet carries the DOT symbol on the back; novelty helmets that lack it are not legal.

At a glance, under Arizona driving laws: helmet law, under 18.

Arizona driving laws: lane splitting

Only lane filtering. Arizona has permitted motorcyclists to move between stopped vehicles at low speed since 2022; splitting lanes in moving traffic is still illegal.

Since September 2022, motorcyclists may pass between stopped vehicles on roads with a speed limit of 45 mph or less, at no more than 15 mph.

Even where it is legal, Arizona driving laws is still subject to reckless-driving laws, so police can stop a rider who rides too fast for conditions.

At a glance, under Arizona driving laws: lane splitting, filtering only.

Where the Arizona driving laws stand out

• New resident deadline: Right away — in the shorter group of 5 in the US
• Filtering only (lane splitting), in the more permissive group of 6 states
