New Hampshire ATV Laws: Registration, Age Rules & Penalties

New Hampshire’s ATV laws sit in RSA Chapter 215-A, which treats ATVs as Off-Highway Recreational Vehicles (OHRVs). If you ride off your own property, the ATV must be registered, and anyone 12 or older behind the handlebars needs either a driver’s license or an OHRV safety education certificate. The rest of the chapter covers equipment, where you can ride, speed, impaired operation, and accident reporting, with penalties running from fines to felony charges when someone is hurt.

What Counts as an ATV in New Hampshire

RSA 215-A:1 defines an ATV as a motor-driven vehicle designed for travel over surfaces other than maintained roads, fitted with non-highway tires, no more than 50 inches wide, and weighing no more than 1,000 pounds unladen dry.¹ A vehicle that fits is an OHRV, and the full body of OHRV rules applies. Larger side-by-sides can fall into a separate utility-vehicle category with different thresholds.

Registering an ATV

Every ATV operated off the owner’s property must be registered. The person registering must be at least 18 and show a valid driver’s license or non-driver photo ID from the Division of Motor Vehicles. New Hampshire does not require a title, bill of sale, or prior registration to complete the process. You do provide the year, make, model, engine displacement, colors, and VIN.²

Registrations run May 1 through April 30 and are handled by the Fish and Game Department, authorized agents, or online. Current fees:

Resident club member: $59
Resident non-member: $89
Non-resident club member: $78
Non-resident non-member: $108
Non-resident 10-day temporary (May through October only): $42

All fees include a $2 transaction fee. The club-member rate requires membership in a New Hampshire wheeled-vehicle club affiliated with the NH Off Highway Vehicle Association, and you must present a membership voucher each time you register.³ You receive a printed certificate and two decals. Affix the decals correctly, and carry the certificate while riding.

Age and Licensing Rules

The age rules are layered, and the liability for getting them wrong often lands on the supervising adult.

Age 12 and Older

Anyone 12 or older must have either a valid driver’s license or a completed OHRV/snowmobile safety education certificate before riding off their own property.⁴ A driver’s license alone is enough. The safety certificate covers both wheeled OHRVs and snowmobiles, so the course is a one-time step.⁵

Under Age 14

Riders under 14 must be accompanied at all times by a licensed adult 18 or older. Any adult 25 or older riding with someone under 14 is presumed legally responsible for that rider’s operation and can be held liable for property damage or personal injury they cause. When a parent, guardian, or designated supervisor is present, liability attaches to that person rather than to other adults in the group.⁴

Under Age 12

Children under 12 cannot obtain a safety certificate or hold a driver’s license, which means they cannot legally cross any public road on an ATV. They can ride on private land belonging to a parent, grandparent, or guardian.⁶

On Designated Public Roads

A rider 12 or older who holds only a safety certificate and is not licensed to drive must be accompanied by a licensed driver at least 25 years old on any road where ATV use is permitted. That supervising adult is legally responsible for any resulting damage or injury.⁴

Passengers and Suspended Licenses

Operators under 18 cannot carry a passenger on a three- or four-wheel ATV.⁶ A suspended or revoked driver’s license bars you from operating any OHRV, and a safety certificate does not override the suspension. Riding while suspended is a misdemeanor if the underlying suspension was DUI-related; otherwise, the minimum fine is $250 for a first offense and $500 for a second.⁴

Required Equipment

Every ATV must have brakes capable of stopping the vehicle within 40 feet from 20 mph, or of locking the wheels to a standstill. Between half an hour after sunset and half an hour before sunrise, at least one working headlight and one taillight are required.⁷ A muffler and exhaust system meeting the state’s noise standards is mandatory, and modifying the exhaust to raise noise above the factory level is prohibited. ATVs also registered for highway use must comply with spark arrester requirements.⁸

All operators and passengers under 18 must wear a protective helmet and eye protection. The helmet requirement applies to passengers under 18 regardless of the operator’s age. There is no state helmet mandate for riders 18 and older.⁴

Where You Can Ride

Private Property

You need written permission from the landowner to ride on anyone else’s private property.⁶ Entering posted land without permission violates RSA 215-A:34.⁹ Landowners who suffer damage from trespassing riders can sue for up to three times the actual cost of cleanup and restoration.¹⁰

Public Roads

ATV operation on public roads is generally prohibited. You cannot ride on the traveled portion or plowed snowbanks of maintained public highways, and interstates, toll roads, and limited-access highways are always off-limits. You may cross a public road if you come to a complete stop, yield to all traffic, cross at roughly a 90-degree angle, and hold either a driver’s license or safety education certificate. Local authorities can authorize ATV use on class IV, V, and VI highways and bridges within their jurisdiction. ATVs may also travel on class I through III-a highways that are not maintained for winter use, as long as those routes are posted for OHRV use.

Designated Trails

The state-managed trail system is where most legal riding happens. Registration is required, and posted trail rules apply. Staying on marked trails protects continued access to the private land that clubs have negotiated permission to cross.

Speed Limits

The statewide maximum on ATV and trail bike trails is 35 mph, and individual trails may be posted lower. A number of named trails carry a 25 mph cap, including the Ammonoosuc Rail, Rockingham Recreational, Sugar River, and Presidential Recreational trails. A 10 mph limit applies within 250 feet of gates and stop signs on bureau trails.¹¹ Whatever the posted limit, operators must ride at a speed reasonable for the terrain, visibility, and conditions.

Impaired Operation and Implied Consent

DUI laws apply to ATVs. The legal blood alcohol thresholds are 0.08 for adults and 0.02 for anyone under 21. By riding, you are deemed to have consented to chemical testing of blood, urine, or breath if an officer has reasonable grounds to believe you’re impaired. Breath results must be provided in writing immediately; blood or urine results within 48 hours by certified mail.¹² An OHRV-related DUI can also trigger a motor vehicle license suspension, which then blocks you from operating any OHRV until it’s lifted.

Reporting an Accident

Any ATV accident that causes death, injury, or property damage above $1,000 must be reported immediately to the nearest police officer or station. A written report on the Fish and Game Department’s form is due within five days. If the operator is incapacitated, the owner of the vehicle must file. Failing to report an accident involving death or personal injury is a felony; failing to report a property-damage accident is a misdemeanor.¹³

Penalties

Most violations of Chapter 215-A are classified as violations, carrying fines but no jail time. Some acts step up to misdemeanor, including refusing to identify yourself to an officer, refusing to produce your registration or license, and taking someone else’s ATV without consent.¹⁰

Minors convicted of any OHRV offense can be fined, ordered to perform community service or take additional safety training, and may have their safety certificate suspended for up to six months. Adults convicted of certain serious violations who have not completed safety training must do so at their own expense within six months, or they lose the ability to register any OHRV or snowmobile until they complete it.¹⁰

Landowners have a separate civil remedy. They can recover cleanup and restoration costs, and courts may award up to three times the actual damages.¹⁰
