Know Before You Go: Michigan Oversize Load Regulations 

Holding valid Michigan Oversize Permits means adhering to strict regulations, and A Permits makes sure you’re fully informed before your trip begins. 

Permitted travel hours are sunrise to sunset. If your load is under 10′ wide, 14′ high, and 90′ long, weekend travel is allowed until 3:00 PM on both Saturday and Sunday. 

If your shipment is overweight only with legal dimensions (and under 70′ in length), continuous travel is permitted, including nights. However, restricted travel applies for loads over 12′ wide or 90′ long during peak hours (7–9 AM and 3–6 PM) in counties such as Wayne, Oakland, Kent, and Macomb. 

We monitor Michigan oversize load regulations to make sure your travel is legal and optimized. 

Bridge Protocols and Escort Rules in Michigan 

When transporting with Michigan Oversize Permits, knowing your bridge requirements is key. For example: 

Mackinaw Bridge: Contact the authority (906-643-7600) 24 hours prior if your load exceeds legal weight or is over 10′ wide. 

Ambassador Bridge (Detroit–Windsor): Charges apply ($50+), and crossing is restricted to 10 AM–4 PM weekdays. 

You may also need escorts: 

Over 90′ long 1 escort 

Over 100′ long 2 escorts 

Over 14′ wide 2 escorts 

Over 15′ high 2 escorts + approved route survey 

We review your dimensions against Michigan oversize and overweight permits requirements to ensure you're set up properly.

Michigan Oversize Permits Cost and Compliance

Our transparent pricing eliminates guesswork and ensures compliance with Michigan oversize load construction restrictions, which can affect routing and timing. 

Michigan Seasonal Load Rules and Restrictions 

Michigan enforces seasonal load restrictions from February to April, during which time Michigan overweight permits are not issued. Axle weight limits may drop by as much as 35%. During this period, approved routing is critical, and we’re here to help you navigate those changes.

For loads traveling under Michigan Oversize Permits, the following equipment is mandatory: 

"Oversize Load" signs on the front and rear of the load 

Red or orange flags at each corner and the widest points 

Lights or lanterns at night if rear overhang exceeds 4′
