In New York, overdimension permits are required for commercial vehicles that exceed the state’s legal size or weight limits. These permits are issued by the New York State Department of Transportation (NYSDOT) and ensure the safe movement of heavy and oversized loads on public highways.
There are two primary types of permits: oversize permits and overweight permits.
What Is an Oversize Permit?
An oversize permit is required when a vehicle or load exceeds New York’s legal dimension limits, even if the weight is within the allowed range.
Common oversize conditions include:
-
Width over 8 feet 6 inches
-
Height over 13 feet 6 inches
-
Length over 65 feet for combination vehicles
-
Excessive front or rear overhang
Oversize permits focus on vehicle dimensions and their potential impact on traffic flow, bridges, tunnels, and overhead structures.
What Is an Overweight Permit?
An overweight permit is required when a vehicle or load exceeds New York’s legal weight limits, regardless of physical dimensions.
Typical overweight thresholds include:
-
Gross vehicle weight over 80,000 pounds
-
Axle or axle-group weights exceeding legal limits
-
Loads that may require special route planning to protect roads and bridges
Overweight permits primarily focus on protecting infrastructure and ensuring roadway safety.
When Are Both Permits Required?
Some loads exceed both weight and dimension limits, requiring carriers to obtain both oversize and overweight permits. Examples include:
-
Large construction machinery
-
Industrial equipment
-
Prefabricated or modular structures
NYSDOT may require route surveys, escort vehicles, or travel restrictions for these loads.

| Typical Limits | Width, height, length | Axle & gross weight |
| Main Concern | Clearance and traffic safety | Road and bridge protection |
