Motorized scooters and mopeds are popular in Washington. They’re convenient, easy to park, and affordable. But if you’re thinking about riding one, it’s important to know what the law says. Washington has different rules depending on the type of scooter or moped you’re using. Things like engine size, top speed, and how many wheels it has will affect whether you need a license or special endorsement.
Here’s a clear look at what’s legal and what’s required if you want to ride a motorized scooter or moped on Washington roads.
What Counts as a Moped in Washington?
In Washington, a moped is defined by a few key features:
- It has two or three wheels.
- It has a motor with less than 50 cubic centimeters (cc).
- It doesn’t go faster than 30 miles per hour on level ground.
- It produces two brake horsepower or less.
- It meets federal motorized cycle standards.
If your vehicle fits all of these points, it’s considered a moped under state law. This is important because mopeds don’t require a motorcycle endorsement. You do still need a valid Washington driver’s license to operate one.

What Counts as a Motorized Scooter?
A motorized scooter is different. Most scooters have engines 50 cc or larger and can go faster than 30 mph. Because of this, they are not license-exempt like mopeds. If you ride a scooter that doesn’t meet the moped rules above, you’ll need a motorcycle endorsement on your license.
Depending on the scooter, Washington offers:
- A two-wheel motorcycle endorsement for two-wheeled scooters.
- A three-wheel endorsement for scooters with three wheels.
- A Category 7 endorsement, which allows operation of scooters that meet certain low-speed vehicle rules.
Do You Need a License for a Moped?
Yes, but not a motorcycle endorsement. If you’re riding a moped that meets the legal definition, you still need:
- A valid driver’s license (any class).
- Vehicle registration.
- A license plate for the moped.
You also must wear:
- A helmet that meets U.S. Department of Transportation (DOT) standards.
- Protective eyewear unless your moped has a windshield.
And just like with any other vehicle, you must follow all traffic laws, including stop signs, traffic lights, and yielding to pedestrians.

Do You Need a License for a Motorized Scooter?
If the scooter doesn’t qualify as a moped (because of engine size or speed), you will need a motorcycle endorsement. Here’s how that works:
- Take a state-approved safety course.
- Pass both a knowledge test and a riding test.
- Finish both tests within 180 days of each other.
The specific endorsement depends on whether your scooter has two or three wheels. Once licensed, you must also register your scooter and display a valid license plate.

Registration and Equipment Rules
Whether you’re riding a moped or scooter, Washington requires proper paperwork and equipment. Here are the basics:
- Riders must be at least 16 years old to operate a moped or scooter.
- Registration must include proof of ownership, the vehicle’s VIN, and your name and address.
- New mopeds need to be titled and registered. If you buy a used one, you must register it within 15 days of purchase.
- Insurance is not required for mopeds, but some riders choose to carry liability coverage just in case.
All mopeds and scooters must have:
- Working lights and brakes
- A muffler and any required anti-pollution devices
Where Can You Ride a Moped or Scooter?
You must follow Washington traffic rules when riding a moped or scooter. Some places are off-limits:
- No riding on sidewalks, bicycle paths, pedestrian trails, or equestrian/hiking trails.
- Freeways and interstates are not allowed for mopeds.
- Lane splitting (riding between cars) is illegal in Washington.
- Park only in designated moped or scooter spaces.
Sticking to the correct roads and following rules helps you stay safe and avoid fines.
What Happens If You’re in a Scooter or Moped Accident?
Accidents can happen even if you follow every rule. If you’re hit while riding a scooter or moped, the other driver may be responsible. Because scooters and mopeds offer little protection, injuries can be serious.
It’s important to:
- Get medical care right away.
- Collect contact information and take photos if you’re able.
- File a police report.
- Talk with a personal injury attorney about your options.
You may be able to get help paying for medical bills, lost wages, and vehicle repairs.
