What Are Maryland Oversize Permits?
A maryland oversize permit is an official authorization issued by the Maryland Department of Transportation State Highway Administration (MDOT SHA) that allows vehicles and loads exceeding Maryland’s standard legal size and weight limits to travel on state highways. Any carrier moving oversized or overweight freight across Maryland without a valid maryland dot oversize permits faces serious consequences — including MDOT SHA fines, forced off-loading, vehicle holds, and delayed deliveries.
Maryland’s location at the heart of the Mid-Atlantic means most oversize routes eventually cross the Capital Beltway (I-495/I-95) or the Baltimore Beltway (I-695) — and Maryland enforces a strict daytime curfew on these corridors specifically. A load that’s perfectly fine to move on most of its route can be barred from completing that route if it tries to cross the Beltway at the wrong hour. Carriers who don’t separate Beltway rules from standard statewide travel hours are the ones who get stopped mid-route.
AONE Permits manages the entire maryland oversize permits process — from the maryland oversize permits login and MDOT SHA portal filing to Beltway curfew verification and provisions compliance. Apply for maryland oversize permits online through our team and get your permit issued fast, accurately, and rejection-free every single time.

Know Before You Dispatch
Maryland Oversize Permit Movement Restrictions
Maryland oversize permit movement restrictions are actively enforced by MDOT SHA and Maryland State Police statewide, with separate, stricter rules applying on the Capital and Baltimore Beltways. Operating outside approved travel hours, ignoring holiday restrictions, or skipping a required escort results in fines, permit revocation, and forced off-loading at the carrier’s expense. AONE Permits tracks MDOT SHA’s restriction schedule in real time to keep your Maryland operation fully compliant.
MDOT SHA Blackout Holiday Periods
- Memorial Day Weekend — Friday noon through Monday midnight
- Independence Day (July 4th) — restricted on the holiday and adjacent days

- Thanksgiving Weekend — Wednesday noon through Sunday midnight
- Christmas & New Year's — December 23 through January 2

- Seasonal load restrictions apply on posted roads during spring thaw (typically February through April)
Maryland-Unique Requirements
Maryland's Beltway Curfew & Permit Cost — What Catches Most Carriers Off Guard
Maryland sits directly on the I-95 Mid-Atlantic corridor, which means a large share of oversize hauls pass through Washington, D.C. or Baltimore at some point. Maryland responds with one of the most specific metro-curfew rules in the country: any load over 45 tons gross, 100 feet long, or 12 feet wide is barred from the Capital Beltway (I-495/I-95) and the Baltimore Beltway (I-695) between 9:00 a.m. and 3:30 p.m. — and loads 14 feet wide or wider face that same restricted window on any Maryland highway, Beltway or not.
Carriers who plan a route around general daylight-hours rules often don’t realize the Beltway segment of their trip has its own narrower restriction layered on top. A load cleared to move at 10 a.m. on a rural stretch of highway may still be illegal to bring onto I-495 at that exact hour. Understanding maryland oversize permit cost is the other piece carriers often get wrong — special hauling permits run $30 for the first 40 tons, plus $5 for each additional ton and another $5 for a 3-day extension, while annual permits run a flat $500 per year. Filing the wrong fee structure causes delays that cost more than the permit itself.
AONE Permits manages both challenges simultaneously. We check your full route against the Capital and Baltimore Beltway curfew before we ever file, and we calculate your precise maryland oversize permit cost upfront — no surprises, no rejected applications, no wasted trips through the MDOT SHA portal.
- Capital Beltway (I-495/I-95) and Baltimore Beltway (I-695): no oversized/overweight travel 9:00 a.m.–3:30 p.m.
- Loads 14′ wide or more face this same restricted window on any Maryland highway, not just the Beltways
- AONE Permits maps your full route against the Beltway curfew before filing — not just the obvious segment
- Special hauling permit: $30 for the first 40 tons, +$5 per additional ton, +$5 for a 3-day extension
- Annual oversize permit: flat $500 per year for pre-approved routes and vehicle types
- Police escort mandatory for loads 16′ wide or more, or exceeding 75 tons gross vehicle weight
Not sure if your route crosses the Beltway curfew window, or what your exact Maryland permit will cost? AONE Permits reviews your complete load specs and gives you clear, exact answers before you apply — one call, zero confusion.
