Truck Parking – Maryland

Truck Parking is available at various locations across Maryland. By far the largest segment of parking is at private truck stops. Parking is allowed on a limited basis at Maryland Welcome Centers. Drivers may also park at Maryland Truck Weigh and Inspection Stations (TWIS), but only when they are closed. Drivers should plan their trips prior to departure, and schedule rest stops well ahead of time. Do not wait until you are tired to seek a place to park. For more information on locations of public and private parking availability click here.

Truck parking on the shoulders of highways and entrance ramps of interstate, US or State highways is unsafe and illegal. Traffic tickets will be issued to violators.
