Super Load Permits: Everything You Need to Know
Super Load for Oversize Loads Permits: At Chicago Permit, we specialize in helping carriers and trucking companies move superloads safely, legally, and affordably across all U.S. states and Canadian provinces. Superloads require additional planning, documentation, and approvals due to their extraordinary size or weight. Below is a complete guide covering what qualifies as a superload, regulations by jurisdiction, estimated costs, and essential considerations.
A Super Load for Oversize Loads Permits is a non-divisible load that significantly exceeds the routine oversize or overweight thresholds set by individual states or provinces. These loads are too large to be transported under regular oversize permits and require special routing, escort vehicles, engineering analysis, and often approval from multiple government agencies.

- Height: Usually more than 15 to 16 feet
- Length: Exceeding 120 to 150 feet
- Weight: Ranging from 130,000 to over 250,000 pounds (varies by jurisdiction)

- Permit Processing Time
Most states and provinces require additional time to review and approve superload permits. Depending on the route and dimensions, it may take from 2 to 30 business days. - Escort Vehicles
Most jurisdictions mandate 1 to 3 escort vehicles, depending on the load’s width, height, and route complexity. Some loads also require police escorts. - Route Surveys & Bridge Analysis
If the load exceeds certain thresholds, an engineering route survey is mandatory. This helps ensure bridges, roads, and infrastructure can handle the load safely. - Travel Time Restrictions
Travel is typically limited to daylight hours on weekdays. Weekend, holiday, or nighttime movement is usually restricted or prohibited without special authorization. - Weather & Seasonal Limits
Some provinces like Alberta, Manitoba, and Saskatchewan enforce spring thaw laws, reducing allowable axle weights during the thaw season to protect roadways. - Insurance Requirements
Carriers may be required to carry high-limit liability insurance (up to $5 million or more), especially when escort vehicles or hazardous routes are involved.
Transporting a superload involves more than just securing a permit. It requires strict compliance with a wide range of state and provincial regulations, operational limits, escort requirements, and weather-based restrictions. Below is an in-depth guide to help you understand the most important superload rules in the U.S. and Canada.
- General Superload Regulations
A superload is generally defined as a load that exceeds standard oversize or overweight dimensions to the point where special handling, approval, and routing are required.
Superloads usually exceed:
Width: 16 feet or more
Height: 15 feet or more
Length: 120 to 150 feet or more
Gross Weight: 130,000 to 254,000 pounds or higher
Each jurisdiction sets its own thresholds and has unique guidelines for approval, which often involve route surveys, structural bridge analysis, and additional documentation. - Operating Time Restrictions
Daylight Hours Only: Most jurisdictions allow superload movement only from 30 minutes before sunrise to 30 minutes after sunset.
Weekend and Holiday Restrictions: Superloads are often prohibited from moving on Saturdays, Sundays, and public holidays.
Urban Curfew Zones: Some states (like Arizona, New York, and California) restrict movement during peak traffic hours in major cities (typically 7–9 AM and 4–6 PM).
Night Travel: Only allowed under special circumstances and may require police escort and additional lighting. - Escort Vehicle Requirements
Escort vehicles (also called pilot cars) are often required to guide and warn other motorists. The number and type of escorts vary by jurisdiction:
One Escort: Typically required for loads over 12 feet wide or 14 feet tall.
Two Escorts: Required for loads exceeding 14 to 16 feet wide or over 120 feet long.
Police Escort: Mandated in several states for extremely heavy or tall loads, or when moving through cities or across narrow bridges.
Height Pole Car: For loads over 15 feet in height to detect overhead obstacles in advance.
Each escort vehicle must meet equipment standards, including signage, flags, lights, and communication devices. - Signage and Lighting Requirements
Oversize Load Banners: Must be displayed at the front and rear of the superload.
Flags: Red or orange flags (18 inches square) are required on the outermost corners of the load and any projections.
Warning Lights: Amber rotating or strobe lights must be used on the towing unit and escort vehicles during movement.
Night Lighting: When night travel is approved, reflective markers and additional lighting must be installed. - Seasonal Load Restrictions
In regions with cold winters, seasonal weight restrictions are enforced during the spring thaw to protect roads weakened by moisture.
Applicable Provinces and States: Includes Alberta, Manitoba, Saskatchewan, Minnesota, Michigan, and parts of the Northeast U.S.
Reduced Axle Loads: Carriers must reduce axle weights by up to 35% during the spring thaw season.
Permit Suspension: In some areas, overweight permits are suspended or restricted during these periods. - Tire Regulations
Superloads must comply with tire size and pressure laws to minimize road wear and ensure safety:
Tire Width-to-Axle Load Ratio: Jurisdictions often limit the maximum axle weight based on the width and number of tires per axle.
Pneumatic Tires Only: Solid tires are typically prohibited for superloads due to road damage risk.
Minimum Tread Depth: Tires must meet minimum depth requirements, generally no less than 4/32″ on steer axles and 2/32″ on other positions.
Inflation Pressure: Must match manufacturer specifications; under-inflated tires may disqualify a load from travel. - Chain Laws in Weather Conditions
Many states and provinces have mandatory chain laws during winter weather conditions. These laws vary widely but are enforced when roads become icy or snow-packed:
Mandatory Chain Zones: Colorado, California, Oregon, British Columbia, and Alberta require chains in designated areas during snowstorms.
Superloads and Chains: Superload haulers must be equipped with sufficient chains to cover all drive tires and may need additional traction devices.
Fines and Denials: Operating a superload without chains in mandatory zones can lead to permit revocation and hefty fines. - Additional Local Restrictions
Bridge Weight Limits: Must be evaluated for each route; some bridges have load or spacing limitations.
Permit Validity: Superload permits are typically valid for one specific trip within a narrow time window (e.g., 5 days).
Route Survey Requirements: For tall or long loads, a certified route survey is often mandatory to avoid conflicts with overhead wires, low bridges, or sharp curves.
Local Permits: Some cities or counties require separate permits to enter certain jurisdictions, especially in urban areas.

Each state sets its own thresholds for what qualifies as a superload. For example, New York considers anything over 200,000 pounds or 16 feet wide a superload, while Massachusetts sets the weight threshold lower at 130,000 pounds. States may also require engineering reviews, police escorts, or structural assessments depending on the route and load.
Superload permit costs vary widely. For example, Texas charges between $60 and $385 for single-trip overweight permits, while Florida may charge a base fee plus a per-ton-per-mile rate. Some states also require annual permits that can cost over $1,000 depending on the load type.

Generally, a superload exceeds 16 feet in width, 16 feet in height, 160 feet in length, or 200,000 pounds in weight. However, these thresholds can vary slightly depending on the state.
In Illinois, a load is considered a superload if it exceeds 120,000 pounds in weight, 145 feet in length, 14 feet 6 inches in width, or 15 feet 6 inches in height. These loads require special permits and may involve additional restrictions such as police escorts or engineering reviews.
