Maryland’s weight review draws from three confirmed official sources: Maryland SHA for permits, Maryland State Police Commercial Vehicle Enforcement Division for enforcement, and Maryland Transportation section 24-111 for the penalty framework. Having all three fields well-sourced is helpful for a state that sits at a major commercial junction — I-95, I-270, and Baltimore port access routes carry heavy freight traffic.
Reading the Maryland weight table
Weight rows use the federal Interstate baseline and the FHWA state law compilation for Maryland. Maryland’s road network combines high-volume Interstate corridors with urban distribution routes, port access, and rural state routes. Federal baseline applies on Interstate routes. For state routes and local roads, verify the FHWA state law compilation and any permit conditions.
Baltimore port access routes and certain urban segments can have tighter effective limits due to infrastructure conditions. When the route includes port area roads or older urban bridges, check current bridge postings before treating the state baseline as sufficient.
Permit and route authority in Maryland
Maryland SHA Hauling Permits is the permit authority for Maryland over-limit moves. Applications go through SHA’s current permit system. Maryland’s urban and port geography means that certain routes require specific approval for over-limit loads. Permits cover route, dates, vehicle configuration, and axle weights. The issued permit covers the specific move — route or equipment changes require permit review.
Seasonal, route, and local checks
No statewide frost-law or seasonal weight restriction was confirmed for Maryland in this review. Maryland’s climate can produce spring conditions that affect local roads, but a statewide seasonal restriction source wasn’t confirmed. Local and county road postings can apply on routes away from the Interstate. For moves that use rural state routes or county roads in spring, checking current conditions is worth the additional step.
Tickets and enforcement notes
Maryland State Police Commercial Vehicle Enforcement Division handles roadside weight enforcement. Maryland Transportation section 24-111 is the official statute reviewed for overweight penalty context. For any citation, the specific Maryland Transportation Code section, excess weight, and court instructions are the controlling documents.
Source-strength notes for Maryland
This page uses 7 source records and carries 3 high-confidence, 23 medium-confidence, and 3 low-confidence fields. Permit agency, enforcement contact, and fine statute all carry direct source support. Seasonal fields did not confirm to a strong statewide source — they land at low confidence.
Building a Maryland source file
A Maryland dispatch file should include SHA permit documentation, current scale ticket, approved route, and the Maryland Transportation 24-111 reference. For I-95 and Baltimore corridor planning, the axle weight table, permit office list, seasonal restrictions, and overweight fines pages support multi-state planning.
How to Read a CAT Scale Ticket covers ticket reading. How to Slide Tandems covers distribution. Bridge Formula Explained covers bridge spacing.
