In Maine you cannot freely drive an ATV on any regular public street. However, you can ride on designated ATV-access routes, winter-closed roads, during declared emergencies, or under a special permit—provided your machine, registration and riding behaviour all meet state and local rules. Below is the full breakdown you need before rolling a four-wheeler onto the tarmac.

1. What counts as an ATV in Maine?
Maine law defines an “all-terrain vehicle” (“motor-driven, off-road, recreational vehicle” with motive power and low-pressure tyres) separately from conventional motor vehicles. Oversized units wider than 65 in or heavier than 2,000 lb can no longer be newly registered, so check width and weight before paying a registration fee. ATVs used solely as a farm vehicle, logging vehicle, or belt-driven vehicle still fall under the same safety rules.
2. Registration basics (and the handy online receipt)
Except on private land you own or lease, every ATV travelling on land in Maine must carry a valid registration plate or digital proof of renewal registration. The new season registration year starts 1 May, and you can renew with authorised registration agents or print an online registration receipt to keep on the machine until the sticker arrives.
3. The default rule: no public roads—unless an exception applies
3.1 General prohibition
Operation of ATVs on a public road, public street, municipal road or highway at grade is prohibited. This includes most motor vehicle traffic corridors, county roads and state highways.
3.2 Legal exceptions you can use
| Exception | What it allows | Key conditions |
|---|---|---|
| ATV-access route | Travel on the extreme right of a road opened by a governmental unit for ATV use | Must go with vehicular traffic; obey prudent speed; road speed limit ≤ 50 mph |
| Winter-closed roads | Drive on roads officially closed to regular motor vehicles in snow season | Follow any signage and spark arrester requirement |
| Emergency conditions | Cross or use a public way during declared periods of emergency | Emergency must be announced by a law enforcement officer |
| Special events & permits | Ride in parades, charity rides or races | Obtain special permit from the governmental unit or special event organiser for limited duration |
| Agricultural or control purposes | Short road hops for farming purposes, trail maintenance, rescue operations or animal-control purposes | Stay within 500 yd and carry tools/gear proving purpose |
4. How roads become ATV-access routes
A municipality, county or unincorporated township may pass an ordinance designating all or part of a trail segment of road as an ATV-access route when it believes opening the way will not compromise public safety. Counties can also restrict or close access routes if they receive complaints about traffic infractions or noise. Always check local websites or club trail updates before planning a ride.
Tip: Look for the green diamond signs with a white ATV symbol. Clubs such as the Lake Moxie ATV Riders often post maps that mark every legal access highway in their area.
5. Equipment for street-legal operation
Before venturing onto asphalt, confirm your machine has:
- Headlights, tail lights and brake lights (must be on from sunset to sunrise and during reduced-visibility hours from sunset).
- An approved spark arrester and muffler meeting 96 dB limits.
- Rear-view mirror, working horn and visible registration plate if required by the town.
- Helmet that meets FMVSS 218; Maine has strict helmet laws for riders under 18 and for passengers on any public street.
- Working parking brake and intact steering for safe operation on mixed terrain.
Some riders add a toggle-switch signal-light kit to improve signalling to motor vehicle drivers, even though blinkers are not universally required.
6. Rider requirements
| Requirement | Details |
|---|---|
| Minimum age | Riders under 16 must complete state-approved safety training and may not cross a public way without adult supervision. |
| Licence | A valid driver licence is not required off-road, but is recommended whenever you mix with vehicular traffic on access routes. |
| Insurance & bodily injury liability | Not mandatory statewide, yet strongly recommended; some towns list it as a permit requirement for special events. |
| Prudent speed | You must keep to a speed that allows complete control on the natural terrain and respect posted limits on access routes. |
7. Where else can you ride legally?
- Designated state-approved ATV trail systems – over 6,000 mi of club-maintained routes, many overlapping snowmobile trails outside winter.
- Cross-country travel on frozen lakes or vernal pools when ice is safe.
- Private land with express permission—Maine’s landowner relations are key to keeping routes open.
- Freshwater marsh and salt marsh areas are generally off-limits to protect fragile ecosystems.
Remember that trail maintenance is funded through your annual registration fee, so stay on marked paths to avoid direct damage and protect future access.
8. Special-use cases
- Rescue operations & emergency conditions – Fire, police or game wardens may commandeer ATVs during the period of emergency.
- Logging or agricultural purposes – You may use an ATV on a short section of public road to reach a logging vehicle landing or pasture when no alternative exists.
- Demonstration event – A special event organiser can request a route closure for an ATV expo or demo ride, subject to a safety inspection and permit process.
9. Enforcement & penalties
Maine game wardens, state police and local law enforcement share authority to stop ATVs on access highways. Failure to obey access-route rules—or operating on a public road without authorisation—can result in:
- A civil fine (often $250-$500) for first offences.
- Impoundment for repeat violations.
- Possible suspension of season registration for reckless operation or bodily injury incidents.
Town councils maintain boards of directors or trail committees to liaise with clubs and address complaints quickly.
10. Practical checklist before you roll onto tarmac
- Confirm legality of the road—check municipal websites or club maps for each ATV-access route.
- Carry your original registration (or online receipt) and a photo ID.
- Inspect lights, brakes and spark arrester; perform a quick safety inspection.
- Keep proof of landowner or governmental unit permission if crossing private driveway gaps.
- Ride at the far right, in the same direction as traffic, and yield to conventional motor vehicles.
- Pack a tow strap, tool kit and first-aid kit for public safety and rescue operations.
- File your route with a friend or local club—especially when planning cross-country travel into remote alpine tundra or marshy segments.
Conclusion: stay informed, stay courteous
So, can you drive an ATV on the road in Maine? Yes—but only on the right roads. Stick to officially posted ATV-access routes, seasonal closures and permitted events; equip your machine for street legal visibility and noise compliance; carry the right paperwork; and ride at a prudent speed that respects both law enforcement officers and neighbouring motorists. Do that, and you’ll discover Maine’s mixed natural terrain offers some of the most scenic, responsibly managed off-highway adventures in the Northeast.
