Fast, reliable & cost effective Equipment Transport

Transporting large or heavy loads in Michigan requires careful planning and compliance with state regulations. Whether you’re moving heavy machinery, oversized construction materials, or industrial equipment, understanding the rules is essential to avoid fines and delays. Freedom Heavy Haul specializes in helping you navigate Michigan’s oversize and overweight vehicle requirements, ensuring a smooth and hassle-free transport experience.

Oversize and Overweight Vehicle Requirements in Michigan

Michigan has specific size and weight limits for commercial and private vehicles. If your vehicle exceeds these dimensions, you will need a special permit before hitting the road.

Standard Vehicle Dimensions

If you’re transporting oversized cargo, it’s important to know the legal size limits before determining whether a permit is necessary.

• Width: 8 feet 6 inches (102 inches)
• Height: 13 feet 6 inches
• Length:
  • Single vehicle: 40 feet
  • Semi-trailer combination: 65 feet (depending on configuration)
  • Truck and trailer combination: 75 feet
• Weight Limits:
  • Single axle: 20,000 lbs
  • Tandem axle: 34,000 lbs
  • Gross vehicle weight: 80,000 lbs (varies based on axle configuration)

If your load exceeds these limits, you’ll need to obtain the right permits before traveling through Michigan.

Permits for Oversize and Overweight Vehicles

Michigan requires special permits for vehicles that exceed legal size and weight limits. Freedom Heavy Haul can assist you in securing the right permit to keep your transport moving without delays.

Types of Permits Available

Different permit types accommodate various transportation needs. The right permit depends on the size of your load and how frequently you need to move it.

Single Trip Permit

This permit is ideal if you’re making a one-time move with an oversized or overweight load. It provides a specific route and time frame for a single transport.

Extended Permit

If you regularly move oversized loads along the same routes, an extended permit is a cost-effective solution. This type of permit typically lasts for one year and covers multiple trips.

Seasonal Permit

Industries like agriculture and logging require seasonal permits that account for road conditions at different times of the year. If your business operates seasonally, this permit ensures compliance while keeping your operations running smoothly.

Super Load Permit

If your vehicle and cargo exceed standard oversize limits by a large margin, you’ll need a super load permit. These loads often require additional safety measures, including route analysis and escort vehicles.

Escort and Safety Requirements

If you’re transporting an oversized load, you may need an escort vehicle to ensure safety and compliance with Michigan’s laws. Freedom Heavy Haul can help coordinate escort services to meet state requirements.

Escort Vehicle Requirements

Escort vehicles warn other drivers and help ensure the safe movement of oversized loads. Michigan’s requirements depend on the dimensions of your load.

Single Escort Vehicle

If your load exceeds 12 feet in width or 90 feet in length, you’ll need one escort vehicle to accompany your transport.

Two Escort Vehicles

If your load exceeds 14 feet in width or 100 feet in length, you must have two escort vehicles—one leading and one following the transport vehicle.

Police Escort

For extremely large or heavy loads, a police escort may be required, particularly when traveling through congested areas or crossing bridges.

Safety Signage and Lighting

Ensuring your oversized load is visible to other drivers is a key part of safe transport.

• “Oversize Load” Banners – These must be placed on the front and rear of your vehicle.
• Red or Orange Flags – These should be attached at the widest points of your load.
• Flashing Amber Lights – Required on escort vehicles and slow-moving oversized trucks to alert other drivers.

Operational Restrictions for Oversize Vehicles

Michigan imposes specific restrictions on when and where oversized loads can travel. These rules help prevent congestion and maintain safety on the roads.

Travel Time Regulations

Certain travel times are restricted for oversized loads. Freedom Heavy Haul can help you plan your route to ensure compliance with these rules.

Daylight Travel Only

Oversized loads can only travel from ½ hour before sunrise to ½ hour after sunset unless you have a special permit.

Weekend and Holiday Restrictions

If your load exceeds 10 feet in width, you cannot transport it on weekends or holidays. These restrictions help prevent traffic disruptions during peak travel times.

Weather-Related Restrictions

Your transport may be delayed if there are hazardous weather conditions, such as high winds, heavy snow, or icy roads. Safety always comes first when moving oversized loads.

Route Approvals and Roadway Considerations

Not all roads in Michigan can handle oversized or overweight loads. Some highways and bridges have special restrictions that require approval before travel.

Highway and Bridge Restrictions

If your load is too heavy for a particular road or bridge, you may need to adjust your route. Freedom Heavy Haul helps you identify the best path to your destination while ensuring compliance with Michigan’s regulations.

Super Load Route Planning

For extremely heavy loads, a structural analysis may be required to confirm that roads and bridges can support the weight. These extra steps help prevent damage to infrastructure and ensure the safety of your transport.

Seasonal Weight Restrictions (Frost Laws)

Michigan enforces frost laws during the spring thaw to protect roads from damage. These seasonal weight restrictions can affect your transport schedule, so it’s important to plan ahead.

How Frost Laws Affect Oversized Loads

During the thawing season (typically February to April), Michigan reduces allowable weight limits on certain roads. If you need to transport a heavy load during this time, Freedom Heavy Haul can assist you in obtaining the necessary exemptions.

Interstate and Cross-Border Travel Regulations

If you’re transporting oversized cargo into another state or Canada, you’ll need to comply with additional regulations.

Crossing into Canada

Michigan shares several border crossings with Ontario. If your load is traveling into Canada, you must meet both U.S. and Canadian size and weight standards. Freedom Heavy Haul ensures all necessary permits are secured for a seamless border crossing.

Interstate Travel Compliance

Different states have their own oversize and overweight vehicle regulations. If your transport route includes multiple states, you must obtain permits for each jurisdiction.

Penalties for Non-Compliance

Failing to comply with Michigan’s oversize and overweight regulations can result in costly fines and delays. Freedom Heavy Haul helps you stay compliant to avoid unnecessary expenses.

Common Violations and Fines

• Exceeding weight limits – Fines start at $50 and increase depending on the excess weight.
• Operating without a permit – Transporting an oversized load without the correct permit can lead to immediate penalties and even vehicle impoundment.
• Failure to use required escorts or signage – Not following safety regulations can result in fines and restrictions on future transport.
