- The registry name, the contract name and the truck lettering should all agree; the status should be active.
- Search the registry by number, then by name, because spellings differ between sources.
- Have the insurer or agent send the certificate of insurance to you, since a license says nothing about coverage.
- Write down the expiry and make sure it outlasts the job.
