Vehicle Restrictions

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

  • 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. Transmissions showing an “S” must demonstrate that this shifter will allow the transmission to be locked into 1st gear.  Model year 2009 and earlier Honda and Acura vehicles must meet the same requirements as described above.  Model year 2010 and later Honda and Acura vehicles are all allowed regardless of transmission type.
  • Maximum wheelbase on any vehicle: 161 inches (This excludes many club cab pickups and limousines).
  • Maximum width on any vehicle: 85 inches including mirrors (mirrors may be folded in to achieve this width).
  • No Hummers, except H-2 & H-3.
  • No trailers, RV’s, campers or 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: 900
  • Dodge Caravan, Plymouth Voyager prior to 1996: 600
