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

Washington driving laws: speed limits

The maximum speed limit in Washington is 70 mph. Rural interstates reach up to 70 mph and urban freeways at up to 60 mph.

State law allows up to 75 mph after an engineering study, but 70 mph is the highest limit posted.

On major roads such as I-5 and I-90, posted limits are frequently below 70 mph, especially through Seattle and in work zones.

Every driver must also hold a speed that suits rain, fog and traffic, even when that means going slower, and officers can write a ticket for that alone.

In short, under Washington driving laws: max speed limit, 70 mph.

Washington driving laws: cell phone and texting law

Only hands-free. Washington has a hands-free law: drivers are not permitted to hold a phone to talk, text or browse behind the wheel. Bluetooth calls and mounted navigation remain legal.

Under the Washington driving laws, a phone in a mount, a voice assistant and one swipe to answer a call or start navigation are permitted; holding the phone at a stoplight is not.

Young motorists get a stricter law: in Washington, permit and intermediate license holders may not use a phone at all, not even through Bluetooth.

Bottom line, under Washington driving laws: phone law, hands-free law.

Washington driving laws: driving age and teen licenses

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

To qualify for the road test, permit holders in Washington need 50 hours (10 at night) of supervised driving.

In short, under Washington driving laws: learner's permit age, permit at 15.

Washington driving laws: minimum car insurance

Washington sets a minimum of 25/50/10 in liability insurance: $25,000 for one injured person, $50,000 for all injuries in one accident and $10,000 for property damage.

Washington follows the at-fault system, so the at-fault driver pays for the other people's injuries and damage through liability coverage.

The legal minimum seldom pays for a serious crash, because medical bills plus a replacement car may exceed $50,000 quickly.

Many agents suggest at least 100/300/100, since damages above your limits can be taken from your savings.

Bottom line, under Washington driving laws: car insurance, 25/50/10.

Washington driving laws: car sales tax

Washington charges a 6.8% state sales tax + motor vehicle tax on vehicle purchases, and local taxes can raise the total.

The 6.5% state sales tax plus a 0.3% motor vehicle sales tax; local taxes bring the total to about 9% to 10.6% in many cities. Since January 2026, an extra 8% luxury tax applies to the part of a vehicle's value above $100,000.

• A $22,700 car in Washington: around $1,544 in state tax
• A $39,050 car in Washington: around $2,655 in state tax
• A $55,000 car in Washington: roughly $3,740 in state tax

A trade-in reduces the Washington driving laws: a $30,000 car with a $5,000 trade-in owes roughly $1,700 compared with $2,040.

In short, under Washington driving laws: car sales tax, 6.8%.

Washington driving laws: car inspection and emissions

No. Washington does not require periodic safety inspections or emissions tests for passenger vehicles.

Washington ended emissions testing in 2020.

Since no safety inspection is mandatory in Washington, keeping brakes and tires in good order is your responsibility.

Bottom line, under Washington driving laws: car inspection, no regular inspection.

Washington driving laws: license and registration deadlines for new residents

After moving to Washington, you have 30 days to obtain a Washington driver's license, and 30 days to register your car.

Step-by-step list for Washington driving laws

• Get a Washington driver's license: 30 days. Bring proof of identity, your SSN and two documents with your new address to the Washington Department of Licensing (DOL) (REAL ID rules).
• Buy car insurance at or above the minimum: Washington requires 25/50/10. A policy is generally mandatory before registration.
• Inspection: No regular inspection, though a VIN check can be needed for an out-of-state car.
• Title and register the car: 30 days at the car licensing office.

The clock generally begins once you start work, rent a home or register kids for school in Washington, not on the day the truck arrives.

At a glance, under Washington driving laws: new resident deadline, 30 days.

Washington driving laws: motorcycle helmet law

Yes. Washington has a universal helmet law: all motorcyclists and passengers has to wear a DOT-compliant helmet, regardless of age. That holds on I-5 and I-90 as much as on local streets in Seattle.

Under the Washington driving laws, operators and passengers of any age must wear a helmet on any motorcycle, and on mopeds that require an endorsement.

NHTSA estimates that helmets prevent around 37% of rider deaths in serious crashes, and 41% for passengers.

Any helmet worn to meet the law carries the DOT label on the back; thin novelty shells without it are not legal.

Bottom line, under Washington driving laws: helmet law, all motorcyclists.

Washington driving laws: lane splitting

No. Splitting and filtering are illegal in Washington. Motorcycles must use a full lane, and riders cannot squeeze between cars or ride between lanes of traffic.

Without a law that allows it, Washington driving laws is treated as an illegal pass or an unsafe lane change, and a collision during a split may count against the rider with insurers.

Bottom line, under Washington driving laws: lane splitting, not permitted.
