Georgia Oversize and Overweight Permitting Requirements

In Georgia, you need an oversize permit whenever a commercial vehicle or its load exceeds the legal limits of 8 feet 6 inches in width, 13 feet 6 inches in height, or 60 feet in length for a single unit. For tractor-trailer combinations, a permit is required if the overall length exceeds 75 feet on non-designated highways or if the trailer length exceeds 53 feet on the National Network. The Georgia Department of Transportation (GDOT) also mandates overweight permits for any vehicle exceeding a gross vehicle weight (GVW) of 80,000 pounds or exceeding specific axle weight limits, such as 20,000 pounds on a single axle or 34,000 pounds on a tandem axle. Failing to obtain these permits prior to movement can result in significant fines and the immediate grounding of the equipment. DispatchTool streamlines this process by providing truck-safe routing that accounts for Georgia’s specific bridge heights and weight restrictions, ensuring drivers stay on approved corridors like I-75, I-85, and I-16. Dispatchers can use the platform to store permit documents and calculate accurate ETAs based on restricted travel hours for wide loads. To manage your Georgia permit compliance and routing, create a DispatchTool account to start planning your next heavy haul.

Georgia Legal Dimension Limits

Georgia Code Title 32 defines the maximum dimensions allowed without a permit. The standard width limit is 8 feet 6 inches. The maximum height is 13 feet 6 inches for all vehicles. For length, a single vehicle is limited to 40 feet, while a truck-tractor and trailer combination is generally limited by the trailer length, which cannot exceed 53 feet on Interstates and designated large-truck routes. If you are traveling on two-lane state routes not part of the National Network, the overall length limit is often capped at 75 feet. Any load protruding more than 4 feet beyond the rear of the vehicle or 3 feet beyond the front must be marked, and if it exceeds these total dimensions, a GDOT permit is mandatory.

Gross Vehicle and Axle Weight Thresholds

The standard maximum gross vehicle weight in Georgia is 80,000 pounds distributed across five axles. GDOT enforces specific weight limits per axle group: 20,000 pounds for single axles and 34,000 pounds for tandem axles. However, Georgia allows for a 5% variance for certain non-interstate travel, though this does not apply to the Federal Bridge Formula on Interstates. If your load exceeds 80,000 pounds GVW, you must apply for a Single Trip, Multi-Trip, or Annual Permit. Loads exceeding 100,000 pounds are subject to stricter bridge analysis and may require specialized routing to avoid structural damage to state-maintained infrastructure.

Types of GDOT Permits and Costs

GDOT offers several permit types based on the frequency and nature of the haul. A Single Trip Permit is valid for 10 days and typically costs $30.00 for standard oversize loads, with additional fees for overweight loads based on total weight increments. For frequent movers, a Standard Annual Permit costs $150.00 and covers loads up to 12 feet wide and 14 feet 6 inches high. For larger configurations, the Annual Plus Permit costs $500.00 and allows widths up to 14 feet. Note that these permits do not exempt carriers from following specific route restrictions listed on the permit document, and they are only valid for the specific vehicle and trailer listed.

Escort Vehicle Requirements (Pilot Cars)

Georgia law requires escort vehicles to ensure public safety when loads reach extreme dimensions. One rear escort is typically required for loads exceeding 12 feet in width on two-lane roads. If a load exceeds 14 feet in width, two escorts (one front, one rear) are mandatory on all highways. Loads exceeding 15 feet 6 inches in width or 100 feet in length often require Georgia State Patrol (GSP) escorts in addition to private pilot cars. Height also triggers escort needs; any load over 15 feet 6 inches requires a front escort equipped with a height pole to check for overhead obstructions like utility lines and low bridges.

Restricted Travel Times and Holidays

Oversize movements in Georgia are generally limited to daylight hours, defined as 30 minutes before sunrise to 30 minutes after sunset. Movement is prohibited on Sundays and major holidays including New Year’s Day, Memorial Day, Independence Day, Labor Day, Thanksgiving, and Christmas. Furthermore, in major metropolitan areas like Atlanta, Savannah, and Columbus, 'Curfew Hours' apply. In Atlanta (counties of Clayton, Cobb, DeKalb, Fulton, and Gwinnett), permitted loads are typically prohibited from the Interstates between 6:00 AM – 9:00 AM and 4:00 PM – 6:00 PM, Monday through Friday, to mitigate traffic congestion.

Signs, Flags, and Lighting Standards

All oversize loads in Georgia must display 'Oversize Load' signs on the front and rear of the vehicle. These signs must be at least 7 feet wide and 18 inches high with black 8-inch letters on a yellow background. Additionally, red or orange fluorescent flags, at least 18 inches square, must be placed at the four corners of the load and at the widest extremities. If a load has a permit for night movement (rare and specific to certain industries), it must be equipped with amber flashing lights visible from 500 feet. Failure to properly flag a load can result in a 'Failure to Comply with Permit' citation, which carries fines starting around $100 plus court costs.

Superload Criteria in Georgia

A 'Superload' in Georgia is defined as any load exceeding 16 feet in width, 16 feet in height, 125 feet in length, or 149,999 pounds in weight. These loads require a significantly more rigorous application process, including a bridge structural analysis performed by GDOT engineers. The review process for a Superload can take 7 to 14 business days, and carriers must often provide a written traffic control plan. Because of the complexity, fees for Superloads are higher, and the permit is only valid for a very narrow window of time and a strictly controlled path.
