When You Need a Thruway Oversize/Overweight Permit
You must obtain a NYSTA permit if your vehicle or load exceeds any of the following legal limits:
Legal Vehicle Dimensions (Without Permit)
-
Width: 8 ft 6 in (102 inches)
-
Height: 13 ft 6 in
-
Length:
-
Single unit: 40 ft
-
Semi-trailer: 53 ft
-
Combination: 65 ft (varies by configuration)
-
Legal Weight Limits (Without Permit)
-
80,000 lbs GVW
-
Standard axle limits:
-
20,000 lbs per single axle
-
34,000 lbs per tandem axle
-
(Spread axles calculated by formula)
-
Any load exceeding these requires a permit—even if you already have an NYSDOT OS/OW permit. NYSTA permits are separate and required specifically to operate on the Thruway.
Types of Thruway Permits
NYSTA offers several types of permits depending on the load and how often you travel:
1. Single-Trip Permit
For one-time travel with an oversize/overweight load.
Valid for a specific route and date.
2. Multi-Trip Permit
For carriers running oversize equipment frequently.
Common for construction fleets, crane companies, heavy haulers.
3. Annual Permit
Allows repeated travel for loads that are oversize but within certain acceptable thresholds (e.g., 12 ft wide or less).
Common Thruway Oversize Limits
Although permits are available, NYSTA has maximum allowable sizes they will approve:
-
Maximum Width: 16 ft (varies by segment)
-
Maximum Height: 14 ft 6 in
-
Maximum Gross Weight:
-
Typically up to 120,000 lbs, depending on axle spacing
-
Some moves require structural review
-
Loads exceeding these limits often require special engineering approval or may be rejected.
Travel Time Restrictions
General Allowed Hours
Most oversize loads can travel:
-
Sunrise to Sunset, Monday through Friday
No Travel Allowed
-
Weekends for many oversize loads
-
Major holidays and holiday weekends
-
