Virginia DOT Weight Regulations: Limits, Permits & Penalties

Virginia limits commercial trucks to 20,000 pounds on a single axle, 34,000 pounds on a tandem axle, and 80,000 pounds gross vehicle weight on interstate highways. Go over those Virginia truck weight limits and you don’t get a flat ticket. The state assesses liquidated damages by the pound, and the rate climbs sharply the further over you are. At 25 percent above the legal gross, the whole bill doubles. Above 50 percent, it triples.

The Core Weight Limits

Three numbers do most of the work. A single axle cannot carry more than 20,000 pounds, and no axle can put more than 650 pounds on each inch of tire width where the tire meets the road. A tandem axle tops out at 34,000 pounds, and no individual axle inside that tandem can exceed the 20,000-pound single-axle cap.¹

Gross Weight Depends on Axle Spacing

Gross weight isn’t a single number. Virginia’s code publishes a table that pairs the number of axles and the distance between the outermost axles with a maximum allowable weight. A five-axle combination with 36 feet between the outer axles can run at 80,000 pounds. A three-axle setup with 20 feet of spacing is capped at 51,500 pounds.¹ Being under 80,000 pounds isn’t enough on its own. A short-wheelbase truck can be illegal at a much lower total.

Interstate Highways

On interstate routes, 80,000 pounds is a hard ceiling regardless of how the vehicle is configured. Single-axle and tandem-axle caps apply the same way, and the axle-spacing table still governs anything below the gross limit.² These numbers match the federal standard at 23 CFR 658.17.³ No Virginia overload permit extends the interstate cap. If you buy extra capacity, you can only use it off the interstate system.

Posted Bridge Limits Override Everything Else

A vehicle at legal weight for the road can still be illegal on a specific bridge. Virginia prohibits any vehicle from crossing a bridge or culvert when its gross weight exceeds the capacity posted on the structure.⁴ Posted limits on older rural bridges often fall well below the standard axle and gross ceilings. Crossing anyway triggers liquidated damages under the same schedule as any other weight violation.

Overload Permits That Raise the Ceiling

Carriers who need to run heavier can buy capacity through a permit, within limits.

The Standard Overload Permit

A standard overload permit adds up to five percent to the single-axle, tandem-axle, and gross weight limits. Annual cost is $250, with quarterly and multi-year options available, and a prorated fee for permits bought between registration renewal periods.⁵ The absolute ceiling with a permit is 84,000 pounds gross, and again, the permit does nothing for interstate travel.⁶ Local, state, and federal government vehicles get two-year overload permits at no cost.

Farm and Forest Product Hauls

Trucks carrying Virginia-grown farm or forest products from the point of production, harvest, or felling to the first processing location can stack a second five percent extension on top of the standard permit. In practice that allows up to ten percent above the base limits. The 84,000-pound gross ceiling still applies, and interstate limits still don’t move.⁷

Vehicles registered as farm-use under Virginia Code § 46.2-698 can operate at these extended limits without a separate permit or fee. Violate the extended limits, though, and the vehicle loses that privilege and must apply for a permit going forward.⁷

What a Violation Actually Costs

Virginia charges by the pound over the limit. Two separate schedules apply depending on whether the violation is on an individual axle or on gross vehicle weight, and axle violations cost more at the higher tiers.

Axle Weight Overages

2,000 pounds or less over: 1 cent per pound
2,001 to 4,000 pounds over: 3 cents per pound
4,001 to 8,000 pounds over: 12 cents per pound
8,001 to 12,000 pounds over: 22 cents per pound
12,001 pounds or more over: 35 cents per pound

Gross Weight Overages

2,000 pounds or less over: 1 cent per pound
2,001 to 4,000 pounds over: 3 cents per pound
4,001 to 8,000 pounds over: 7 cents per pound
8,001 to 12,000 pounds over: 12 cents per pound
12,001 pounds or more over: 20 cents per pound

Every violation carries an additional $20 assessment. Permit holders who exceed their permitted weight face a separate 20 cents per pound over the permit limit.⁸

Doubling and Tripling

Gross weight 25 to 50 percent above the lawful limit doubles the entire liquidated damages amount. More than 50 percent over triples it. Pickup and panel trucks are exempt from the multipliers.⁸ A five-axle rig running 100,000 pounds on an 80,000-pound route is 25 percent over. Base damages on 20,000 excess pounds at the top gross rate come to $4,000, which the multiplier pushes to $8,000, plus the $20 assessment.

The One-Time Waiver

A driver with no prior weight violations who is caught 1,500 pounds or less over can ask the general district court to waive the liquidated damages. The court decides whether to grant it, and the waiver is available only once. Collected damages go to the State Treasurer and fund highway construction and maintenance.⁸

How Weighing Works on the Road

Virginia runs 13 permanent Motor Carrier Service Centers and 12 mobile enforcement crews. Seven of the fixed sites sit on interstate routes, four use weigh-in-motion sensors that screen trucks at highway speed, and a mobile unit combines weigh-in-motion, static scales, and signage.⁹

Being Directed to a Scale

An officer or compliance agent who has reason to believe a truck is overloaded can require it to be weighed. If the stop is within 10 road miles of a permanent station, the officer may send the driver there, and the driver can insist on being weighed at that station rather than on portable equipment. Beyond 10 miles, wheel-load weighers can be used on the spot. Refusing to drive to the station or cooperate with the weighing is a Class 4 misdemeanor.¹⁰

Shifting the Load

When gross weight is legal but an axle is overloaded, the driver gets one hour to shift the load at the weighing site. The trap: liquidated damages are still calculated from the pre-shift weight in most cases. The damages disappear only in specific situations, namely when the driver corrects the problem by sliding the semitrailer axles or the tractor’s fifth wheel, when repositioning off-road mobile construction equipment, or when the vehicle qualifies for the farm and forest product extensions on a non-interstate highway.¹⁰

Placarded hazardous materials cannot be shifted at all. The vehicle has to be handled through other means before it moves.¹⁰

The Federal Safety Record Consequence

Weight violations don’t end when the check is written. The Federal Motor Carrier Safety Administration tracks regulatory violations through its Compliance, Safety, Accountability program, and both the frequency and severity of those violations feed into a carrier’s federal safety rating.¹¹ Carriers with weaker scores get pulled into inspections more often and bypass fewer weigh stations that use electronic screening. Strong records commonly bypass 95 percent or more of participating stations; marginal ones can be pulled in at half or more.

Repeated violations can also prompt a compliance review, which looks at whether the pattern is worsening. FMCSA treats a run of overweight stops as a signal of load-planning or dispatch problems rather than a driver mistake, and that framing weighs heavily when the agency considers a rating downgrade.¹¹
