Maryland Truck Speed Limit
No split in Maryland. Trucks run the same posted limit as cars, up to 70 mph on interstates and expressways (Md. Transp. Code § 21-801.1). Nothing over 70 is legal anywhere in the state, and 55 caps any road that isn't an interstate or expressway. Watch the work-zone speed cameras — the SafeZones program mails tickets, no officer needed.

Truck-specific rules and quirks
- Nothing over 70 mph is legal anywhere in Maryland, and 55 is the ceiling on any road that isn't an interstate or expressway. Maryland's SafeZones program runs automated work-zone speed cameras that mail tickets with no officer present.
What a speeding ticket costs
Ordinary speeding is graduated and set by the District Court, not a flat number. No special reckless-over-X-mph criminal statute like Virginia's. Work-zone speed-camera citations run about $40 and don't carry points.
