Delaware Trucking Regulations

Delaware is the second smallest U.S. state by area but sees disproportionately high commercial vehicle traffic as a through-state on the I-95 Northeast Corridor between Philadelphia and Baltimore/Washington. The Delaware Memorial Bridge (twin spans on I-295/I-495) is one of the most critical freight chokepoints in the region, with weight and height restrictions that affect routing for oversize loads. The Port of Wilmington handles significant refrigerated cargo including bananas, produce, and juice — creating fresh goods drayage demand along the I-95 spine. Delaware's Division of Motor Vehicles handles IRP and IFTA credentialing. DelDOT manages infrastructure and oversize/overweight permitting. Despite its small size, Delaware's position in the Mid-Atlantic freight network means carriers frequently transit the state without making local deliveries, and compliance with weigh station stops on I-95 is routinely enforced.

Frequently asked questions

Are there weight restrictions on the Delaware Memorial Bridge?

Yes. The Delaware Memorial Bridge has posted weight restrictions for certain vehicle configurations that differ from standard Interstate weight limits. Carriers with overweight loads must obtain a DelDOT permit and verify that their specific configuration is cleared for the bridge before crossing. Standard legal loads meeting federal weight limits can cross without a special bridge permit.

Does Delaware require me to stop at weigh stations if I'm just passing through?

Yes. All commercial vehicles must stop at open Delaware weigh stations regardless of origin or destination. The primary I-95 weigh station is at the Maryland border and the Wilmington area. PrePass transponders may provide clearance for eligible vehicles after a virtual weigh-in.

What are the credentialing requirements for the Port of Wilmington?

Carriers serving the Port of Wilmington must register with the port and obtain access credentials through the Wilmington Port Authority. Drayage drivers may also need TWIC (Transportation Worker Identification Credential) cards depending on the terminal access requirements.

How do I obtain an oversize/overweight permit in Delaware?

DelDOT issues oversize and overweight permits through its online permit system. Loads requiring movement on state routes — including the Delaware Memorial Bridge — need route-specific approval. Single-trip and multi-trip permits are available; fees are based on dimensions and weight.
