I-95 is the default commercial-coach corridor between Washington and Baltimore; National Park Service rules restrict commercial vehicles, including buses over 10,000 pounds, from the Baltimore–Washington Parkway without permission. At Washington DC to Baltimore, that local setting affects maneuvering and waiting as much as the seat count does.
