45. Driving licence

A driving licence is an official document authorising a person to drive one or more specified categories of motor vehicle. It may contain conditions, restrictions, category codes and expiry dates that determine which vehicles the holder may drive.

Drivers must hold a licence that is valid for the vehicle category and jurisdiction concerned. A licence may be provisional, full, restricted, suspended or withdrawn, and additional qualifications may be required for professional driving.

Which driving-licence entitlement is needed for an ordinary car in the United States?

In the United States, ordinary car licensing classes vary by state, so a single national class letter should not be assumed. A different entitlement may be needed for motorcycles, heavy vehicles, trailers or passenger transport.

Can a visitor drive in the United States using a driving licence issued abroad?

The rules are set by the individual state. Some visitors may drive on a valid foreign licence, while some states require an IDP as well. Check the state motor-vehicle agency for recognition, vehicle class and duration.

Does an International Driving Permit replace the original licence in the United States?

No. An International Driving Permit (IDP) is not a standalone driving licence. Where it is recognised or required, carry the underlying valid licence as well and check the accepted convention or translation requirements. An IDP cannot override a suspension, unsuitable vehicle category or local minimum age.
