6.2 Mopeds, Motorized Scooters, Limited Use & Low-Speed Vehicles
Key Takeaways
A Massachusetts moped (motorized bicycle) tops out at 30 mph or less, has an engine of 50 cc or less and an automatic transmission, and may not be ridden faster than 25 mph.
Massachusetts motorized scooters may not exceed 20 mph or be ridden after sunset or before sunrise, carry no passengers, and are not registered by the RMV.
A limited use vehicle can go faster than 30 mph but not more than 40 mph and may not be driven on any road with a speed limit over 40 mph.
A Massachusetts low speed vehicle has four wheels, a top speed of 20 to 25 mph and a gross weight rating under 3,000 pounds, and may not be driven on roads posted over 30 mph.
Every moped, motorized scooter, limited use vehicle and low speed vehicle operator in Massachusetts needs a valid license or learner's permit.
Students and parents often ask whether a teen needs a license for "that scooter" or a golf-cart-style vehicle. The Manual answers with four separate definitions, and exam questions turn on their speeds, license classes and road limits.
The Four Vehicle Types at a Glance

| Operating speed limit | No faster than 25 mph | No faster than 20 mph | — | — |
| License | Valid license (any class) or permit | Valid license (any class) or permit | Class M if a motorcycle; Class D if a passenger vehicle (license or permit) | Class D license or permit |

Moped Rules in Detail
You must have a valid driver's license of any class, or a learner's permit, to ride a moped. While riding you must:
- go no faster than 25 mph;
- stay off limited-access or express state highways posted against bicycles;
- use the correct electronic and hand signals before stopping or turning;
- stay off off-street recreational paths (bicycle lanes along roads are allowed);
- make sure the driver and any passengers wear helmets that meet or exceed the U.S. DOT standard;
- obey all traffic laws;
- carry no passengers when riding on a learner's permit.
Violating any of these rules can bring a fine of up to $100. Section 6.1 notes that mopeds share the bicycle's right to the road and need the same four-foot passing space.
Motorized Scooter Rules in Detail
Important
The RMV will not register motorized scooters, but riders still need a valid license (any class) or learner's permit and can be ticketed for motor vehicle violations.
A motorized scooter rider must:
- go no faster than 20 mph;
- stay off limited-access or express state highways;
- wear a U.S. DOT-standard helmet;
- stay to the right side of the road, even when passing another vehicle;
- use electronic and hand signals before stopping or turning;
- not ride after sunset or before sunrise;
- carry no passengers;
- obey all traffic laws.
Fines run up to $25 for a first offense, $25–$50 for a second and $50–$100 for a third or later. The Manual notes that fees are subject to change.
Limited Use and Low Speed Vehicles
- A limited use vehicle sits between a moped and a normal vehicle: faster than 30 mph but no faster than 40 mph. Whether it counts as a motorcycle (Class M) or a passenger vehicle (Class D) depends on how many wheels it has. It may not use limited-access or express state highways or any road posted over 40 mph.
- A low speed vehicle has four wheels, travels between 20 and 25 mph and weighs under 3,000 lb gross. It requires a Class D license or permit. It may not use limited-access or express state highways or any road posted over 30 mph, and may be barred from heavy-traffic areas. LSV drivers must obey all traffic laws.
Tip
Memory hook for the speed caps (what the operator may do): moped 25, scooter 20. For the road ceilings (what roads the vehicle may use): LUV 40, LSV 30.
Bicycle Safety Law Changes
The Manual's "Bicycle Safety Laws" summary reflects updates that put more responsibility on cyclists, motorists and bike renters, and gave police more training in bicycle enforcement:
- A police officer who sees a bicyclist commit a traffic violation can issue a citation just as for a motorist. The cyclist can be fined, but it does not affect their driving record.
- A bicyclist must give the officer their true name and address when asked. They can be fined for refusing and arrested for refusing to give their name.
- Companies that rent bicycles must offer helmets that meet all safety requirements.
- Motorists can be cited for a motor vehicle violation for certain behavior around bicycles. The detailed list, such as cutting off a cyclist after passing or opening a door into one, is in sections 13.2 and 13.3.
Answering Family Questions About Small Vehicles
- When a family asks about a teen's scooter or moped, the answer is the same: a license or permit is required, helmet rules apply, and highway and nighttime limits differ by vehicle type.
- Explain the difference between a speed cap and a road ceiling: a moped rider may not exceed 25 mph, while an LSV driver may not use a road posted over 30 mph.
- Expect low-speed and light vehicles to travel well below the traffic flow. Plan passing with the four-foot rule where the operator is a vulnerable road user.
