Expert Guidance for Specialized Loads

Every professional in the freight and logistics industry knows: Montana’s vast highways present unique challenges for oversize and overweight loads. That’s why Overweight Permit is committed to making your journey through regulatory requirements simple and stress-free. We specialize in helping carriers secure all types of Montana Oversize Permits, ensuring you stay compliant, efficient, and fully supported from start to finish.

When Is a Montana Oversize Permit Necessary?

Montana requires permits for any vehicle or load that exceeds state legal limits:

Width above 8′6″

Height over 14′

Length over 75′ (including overhang)

Gross weight over 80,000 pounds (subject to axle group regulations)

If your truck falls into any of these categories, you will require one or more of the following permits:

Montana Oversize Permits: For vehicles exceeding statutory dimensions

Montana Overweight Permits: For trucks over 80,000 pounds

Montana Overhang Permits: If your total length with overhang surpasses 75′

Montana Single Trip Permits: For unique, non-recurring moves

Montana Annual Permits: The solution for frequent, repetitive routes

Understanding Montana Oversize Overweight Permits Requirements

Understanding the specifics of Montana oversize overweight permits requirements is essential for legal and safe travel. Our experts guide you through:

Routine permit limits (Length up to 150′, Width up to 18′, Height up to 17′, plus axle/group-based weight constraints)

Montana policies for divisible and indivisible loads

Special considerations for spring thaw and Red Route highways

If your load exceeds routine limits, you’ll need a Montana super-load application—we’ll simplify the process for you.

Montana Permits Validity and Travel Hours

Your working schedule is important, and so is understanding permit durations:

Montana oversize permits are valid for 3 to 5 days perfect for planned or emergency moves.

Loads up to 10′ wide, 15′6″ high, or 110′ long can run continuously, including nights and weekends.

Larger loads may require travel during daylight hours, with restrictions on certain highways and especially during weekends or holidays. On Red Route highways, stricter curfews apply. Always consult the state’s Red Route Map for up-to-date restrictions.

Escort, Signage, and Lighting Compliance

Safety is non-negotiable. Montana requires:

Escorts for oversize/overweight moves above certain thresholds. For example, interstate loads over 120′ or 16′6″ generally need an escort vehicle; even wider, taller, or heavier loads may require two or more escorts, particularly on two-lane roads.

Mandatory “Oversize Load” signs and prominent amber lights for vehicles exceeding 10′ wide.

Rear “Long Load” signs for combinations exceeding certain lengths.

Proper flagging at all protruding corners or edges

We keep you updated on all Montana oversize permit regulations to prevent unnecessary stops or penalties.
