FAQ

Where should I verify New Jersey permit requirements?

Use the official NJDOT Trucking / Oversize-Overweight Permits source linked on this page before moving over legal size or weight.

Are New Jersey seasonal restrictions fully confirmed here?

No. This review did not confirm a statewide seasonal or frost source, so route and permit restrictions still need checking.

Do these Interstate-based limits apply to New Jersey state roads?

The values shown are the federal Interstate baseline. State-specific non-Interstate limits are in the FHWA state law compilation linked here and may differ from the baseline.
