Overweight / Overload Trip Permits Explained
General information for motor carriers · Not legal advice.
When a load is too heavy or too large for a state's standard legal limits, you need an oversize/overweight (OS/OW) permit to move it legally. An overweight trip permit authorizes a specific over-limit move along a defined route for a limited time.
When You Need a Permit
You need one any time your vehicle and load exceed a state's limits for:
- Weight (gross or per-axle)
- Width, height, or length
Each state sets its own limits and permit rules, so a multi-state move can require permits from several jurisdictions.
What's Typically Required
- Vehicle and load dimensions and weight
- Axle count and spacing
- Planned route and travel dates
- Carrier and vehicle details
Large loads may also require escort (pilot) vehicles or restricted travel times.
