OSOW Permit Services
An Oversize and Overweight (OSOW) permit is required whenever a commercial vehicle exceeds a state's legal size or weight limits. Because each state has its own permitting regulations, carriers transporting OSOW loads across multiple states often need separate permits for every jurisdiction they enter.
Atlantic Unity LLC provides nationwide OSOW permit services for carriers moving freight throughout the 48 contiguous states. Whether your shipment requires a single-state permit or a multi-state permit package, our team ensures every permit is obtained accurately and on time.
