North Dakota Weigh Stations and Commercial Vehicle Enforcement

The North Dakota Department of Transportation (NDDOT) and the North Dakota Highway Patrol (NDHP) manage the state's commercial vehicle weigh stations to ensure compliance with weight, size, and safety regulations. These facilities are primarily located along major freight corridors including Interstate 94 and Interstate 29, as well as high-traffic state highways serving the Bakken oil region. Drivers operating vehicles with a Gross Vehicle Weight Rating (GVWR) exceeding 10,000 pounds are generally required to pull into open stations, though specific signage may indicate different requirements for empty vehicles or specific cargo types. Efficiency at these checkpoints is vital for maintaining Hours of Service (HOS) compliance and meeting delivery windows. DispatchTool integrates truck-specific routing to help drivers identify active weigh station locations along their North Dakota routes and manage digital documents needed for inspections. By consolidating IFTA data and load information in one platform, drivers can quickly provide necessary documentation if pulled in for a Level I, II, or III inspection.

North Dakota Highway Patrol Enforcement

The North Dakota Highway Patrol (NDHP) is the primary agency responsible for enforcing Title 39 of the North Dakota Century Code, which governs motor vehicle operations. Enforcement is carried out through fixed weigh stations and mobile scale units that can be deployed to any location, including rest areas or paved turnouts. In 2023, the NDHP conducted thousands of inspections, focusing on safety violations and weight limits to preserve infrastructure. Fixed scales are typically staffed during peak hauling hours, but mobile enforcement is active 24/7 across the state’s 8,600 miles of state highways.

Primary Weigh Station Locations

North Dakota operates several key fixed facilities. Notable locations include the Beach station on I-94 EB near the Montana border, the Mooreton station on I-29 NB, and the West Fargo station on I-94 EB. On I-29, stations are strategically placed near Joliette for southbound traffic and near Mooreton for northbound traffic. These stations utilize static scales and sometimes weigh-in-motion (WIM) technology to sort vehicles. Drivers should monitor overhead electronic signs, as North Dakota frequently uses 'Open' or 'Closed' light systems to direct traffic flow.

Bypass Programs: PrePass and Drivewyze

North Dakota participates in major electronic bypass programs to reduce congestion at scale houses. PrePass is available at several high-volume locations, allowing carriers with high safety scores to bypass without stopping. Drivewyze PreClear is also supported, providing mobile-based bypass notifications at over 10 sites across the state. Eligibility for a bypass is determined by the carrier's CSA score and historical safety data provided by the FMCSA. Using these systems can save an average of 5 to 15 minutes per station and approximately 0.4 gallons of fuel per avoided stop.

North Dakota Weight Limits and Overweight Permits

The legal gross vehicle weight limit on North Dakota interstates is 80,000 pounds, provided the vehicle meets the bridge formula requirements. For non-interstate highways, the limit can reach 105,500 pounds depending on axle configuration. Single axles are limited to 20,000 pounds, and tandem axles are limited to 34,000 pounds. Carriers exceeding these limits must obtain an Overweight/Oversize (OW/OS) permit through the NDDOT's online permit system. Fees for these permits vary; for example, a single-trip permit starts at $20, but significantly heavier loads incur ton-mile charges based on the distance traveled.

Frost Laws and Seasonal Weight Restrictions

During the spring thaw, typically between March and May, North Dakota implements 'Frost Laws' to protect saturated roadbeds. The NDDOT categorizes roads into different load levels: Legal Weight, 7-ton, 6-ton, and 5-ton restricted routes. A 7-ton restriction means the maximum weight on any single axle cannot exceed 14,000 pounds. These restrictions are strictly enforced at weigh stations and by mobile units. Violating seasonal weight limits can result in fines exceeding $1,000, depending on the number of pounds over the restricted limit as per NDCC 39-12-17.

Agricultural Exemptions and Requirements

North Dakota provides specific exemptions for the transportation of agricultural products under NDCC 39-12-05.3. During harvest seasons, certain agricultural vehicles may be allowed a 10% weight cushion for specific commodities, though this typically does not apply to Interstate highways. Drivers must still stop at weigh stations unless they have a specific bypass signal. Even with exemptions, vehicles must not exceed the tire weight rating, which is generally 550 pounds per inch of tire width. It is critical for drivers to carry documentation proving the origin and destination of the agricultural load.

Inspection Types and Documentation

When directed into a North Dakota weigh station, drivers may undergo an North American Standard Inspection. A Level I inspection is the most thorough, covering both the driver's credentials (CDL, Medical Card, HOS logs) and the vehicle's mechanical condition (brakes, lights, tires, coupling devices). According to FMCSA data, North Dakota inspectors frequently cite lighting violations and logbook inaccuracies. Drivers are required to present their Record of Duty Status (RODS) for the current 24-hour period and the previous 7 consecutive days, usually via an Electronic Logging Device (ELD).

Frequently asked

Which vehicles must stop at North Dakota weigh stations?

All commercial vehicles with a GVWR over 10,000 pounds are required to stop at North Dakota weigh stations when they are open, unless they receive a bypass signal from an electronic system like PrePass or Drivewyze.

What are the fines for being overweight in North Dakota?

Fines are calculated based on the amount of excess weight. For example, under NDCC 39-12-17, carrying 5,000 pounds over the legal limit can result in a fine of 10 cents per pound, totaling $500, plus potential court costs.

Does North Dakota use weigh-in-motion (WIM) technology?

Yes, North Dakota utilizes WIM sensors embedded in the roadway at several locations on I-94 and I-29 to screen trucks at highway speeds. This allows compliant trucks to be diverted back to the main lanes without coming to a complete stop.

Are there weigh stations on North Dakota state highways?

While most fixed scales are on Interstates, the North Dakota Highway Patrol operates portable scales on state highways like US-2, US-83, and US-85, especially in the western oil regions to monitor heavy equipment transport.

Where is the main weigh station on I-94 Westbound?

The primary westbound station on I-94 is located near West Fargo. There is also a major enforcement presence near the Montana border at the Beach, ND station.
