Safety considerations dictate that some vehicles cannot be permitted on the Auto Road:

•     Acura, Honda, Jaguar, Saturn and Sterling autos with automatic transmissions must show a "1" or  "L" or "S" on the shifter to be allowed on the Auto Road.
•    Maximum wheelbase on any vehicle: 161 inches (This excludes most club cab pickups and limousines).
•    Maximum width on any vehicle: 80 inches including mirrors.
•    No Hummers, except H-3.
•    No trailers, RV's, campers or oversized vans converted to RV's.
•    No mopeds or scooters.
•    No dual wheeled vehicles.
•    No pickups with permanent additions that extend wider than the cab (campers, rack bodies, or very wide mirrors).
•    Some former police cars and taxis have the 1st gear locked out and cannot be allowed on the road.
•    No Lincoln Continentals 1969 or earlier.
•    No bicycles.

Weight Limits:
These are approximate numbers used as guidelines. Weights (in pounds) include passengers and luggage:

•    Full size car or wagon: 900
•    Mid sized car & compact cars: 800
•    Dodge Caravan, Plymouth Voyager prior to 1996: 600
•    Dodge Caravan, Plymouth Voyager 1996 and newer: 900
•    All other mini-vans: 850
•    3/4 or 1/2 ton van, pickup or SUV: 900
•    One-ton van or pickup: 1050

ATVs on the Auto Road:
Individual ATV traffic is not allowed on the Mount Washington Auto Road. Due to the aggressive nature of the tires on these vehicles, the gravel portions of the Auto Road experience a much higher than normal maintenance need when ATVs are present. This basic fact, along with the unnecessarily aggressive operation of these vehicles by a small number of riders causes us to prohibit their use day to day. 

We will continue to welcome well-organized ATV groups who have reserved with us in advance. Rides during regular operating hours as well as special evening rides preceded by a barbeque at the base of the Road are available. Group rides have a 35-vehicle minimum for day trips and a 30-vehicle minimum for evening trips. Call 603.466.3988 or email amy@mtwashingtonautoroad.com  or mary@mtwashingtonautoroad.com for reservations.

OHRV Trail Bikes will not be permitted on the Auto Road unless they are registered for highway use.

ATV restrictions:
•    The operator must have a valid driver's license with them.
•    Only one person to an ATV unless it is factory designed for two people. No aftermarket add-on seats are allowed.
•    Vehicles must travel single file.
•    The vehicle must be operated on the normal Auto Road surface only. There are no ATV trails and no off-road terrain is available on Mount Washington.

Important note: To be in line with NH RSA 215-A concerning OHRV registrations, all ATVs must have a NH or VT registration. For more information about registration, click here for a NH OHRV FAQ page. For information about NH RSA 215-A, click here.
