Most runs employ at least two double-ended diesel ferries, making the crossings in opposite directions. All ferries are capable of carrying large trucks as well as cars, bicycles, and foot passengers and are of a roll-on, roll-off design (although they can operate single-ended in the event of an engine failure). Credit cards are not accepted on some routes. Under the terms of the Maritime Transportation Security Act, vehicles and luggage brought on board some LCT vessels may be subject to search. Most runs are considered quite scenic.
