Maryland overweight truck violations are governed by the weight limits in Title 24 of the Transportation Article, layered over the federal limits that apply on the interstate system: 80,000 pounds gross, 20,000 pounds on a single axle, 34,000 pounds on a tandem axle, and the Federal Bridge Formula, which can make a load illegal on a given axle group even when the gross weight is under 80,000. Maryland’s fine schedule runs per pound over the limit — roughly 1 cent per pound for the first 1,000 pounds over, then about 5 cents for each additional pound, plus court costs — and a vehicle more than 5,000 pounds overweight cannot be moved until the excess is unloaded. But here is the part that surprises many commercial drivers: an overweight violation does not disqualify your CDL, and unlike the major and serious moving violations, it is one of the few offenses that can still be resolved with a Probation Before Judgment. Understanding both the cost and that important distinction is the key to handling one of these tickets.
Overweight enforcement in Maryland is aggressive — the State Police Commercial Vehicle Enforcement Division and the Maryland Transportation Authority Police run weigh-and-inspection stations and roving portable-scale patrols across the state. But of all the citations a commercial driver can receive, overweight is treated the most differently under the CDL rules, and that changes the strategy.
Maryland and Federal Weight Limits
The baseline weight limits on Maryland’s portion of the interstate system mirror the federal maximums:
- 80,000 lbs gross vehicle weight;
- 20,000 lbs on a single axle;
- 34,000 lbs on a tandem axle group; and
- 42,500 lbs on a tridem axle group.
The Federal Bridge Formula adds another layer: it limits how much weight may sit on a group of axles based on the spacing between them. The practical consequence is that a truck can be under 80,000 pounds gross and still be cited if an axle group exceeds its Bridge Formula maximum — which is why how a load is distributed matters as much as the total weight. Loads exceeding these limits require an overweight (exceptional hauling) permit, which must be carried in the cab and which ties the move to specific routes and conditions.
How Maryland Overweight Fines Work
Maryland calculates overweight fines on a per-pound basis under § 24-111. The general structure is approximately 1 cent per pound for the first 1,000 pounds over the applicable limit, then about 5 cents per pound for every additional pound over, on top of court costs. Because the fine scales with the overage, a modest violation might cost a few hundred dollars while a significant one climbs quickly into four figures.
Two enforcement consequences go beyond the fine:
- The load can be grounded. A vehicle found more than 5,000 pounds over an allowable limit may not be moved until the excess weight is offloaded — which means arranging another truck or storage on the spot.
- A permit can be confiscated. For a violation of a permitted move exceeding 5,000 pounds, the exceptional hauling permit itself can be confiscated by enforcement.
An overweight violation is a misdemeanor under the Maryland Vehicle Law, and it adds to the carrier’s federal CSA (Compliance, Safety, Accountability) score, which can affect audit frequency and insurance.
The Key CDL Distinction: Overweight Is Different
This is the most important point for a CDL holder. The major and serious moving violations covered in CDL disqualifications in Maryland trigger mandatory disqualification and cannot be hidden, because the federal masking prohibition blocks PBJ and diversion for them. Overweight violations are carved out of that rule.
The masking prohibition under 49 CFR § 384.226 expressly excludes “parking, vehicle weight, or vehicle defect violations.” That means two things for an overweight ticket:
- It is not a disqualifying offense. An overweight conviction does not count as a major or serious violation and does not trigger CDL disqualification under § 383.51.
- It can be masked. Because weight violations are exempt from the anti-masking rule, the Probation Before Judgment that is off-limits for a CDL holder’s moving violations is available for an overweight ticket — a tool to keep the conviction off the record.
So while an overweight ticket can be expensive, it does not carry the career-ending disqualification risk of a DUI, reckless driving, or a second serious violation. For why that contrast matters, see how traffic tickets affect a Maryland CDL.
Who Actually Pays
Responsibility for an overweight fine is often contested between driver and company. Owner-operators generally absorb the fine themselves. Company drivers frequently have a contract clause making them responsible if they failed to scale the load before the trip — but whether the overage was actually the driver’s fault is a real question. Loads are often sealed, pre-loaded, or weighed inaccurately by the shipper, and a driver may have had no practical way to know or correct the weight. That responsibility question can matter both for the citation and for any dispute with the employer.
Defenses to an Overweight Citation
Overweight cases can be contested or mitigated on several grounds:
- Scale accuracy and calibration. The scale used to weigh the vehicle must be accurate and properly certified. Records of its calibration are fair game, and a scale that wasn’t properly maintained can undermine the reading.
- Weighing procedure. How the vehicle was weighed — whether on a level surface, fully on the scale, with proper axle measurement — can affect the result.
- Permit and registration questions. Whether a valid permit covered the load, or whether the vehicle was within its registered weight, can change the analysis.
- Mitigation toward PBJ. Because overweight can be masked, a Probation Before Judgment that avoids the conviction is a realistic objective even where the weight isn’t seriously disputed.

Expensive, But Not Career-Ending — Handle It Right
An overweight ticket can cost real money and ground your load, but it won’t disqualify your CDL — and because weight violations can be masked, a PBJ that keeps it off your record is on the table. The questions worth pursuing are whether the weight reading holds up, whether a permit covered the load, and who was actually responsible. A Maryland traffic lawyer can review the citation and the scale records and work to reduce the fine or keep the conviction off your record.
