List of countries by minimum driving age
The minimum driving age is the minimum age at which a person may obtain a driver's licence to lawfully drive a motor vehicle on public roads. That age is determined by and for each jurisdiction and is most commonly set at 18 years of age, but learner drivers may be permitted on the road at an earlier age under supervision. Before reaching the minimum age for a driver's licence or anytime afterwards, the person wanting the licence would normally be tested for driving ability and knowledge of road rules before being issued with a licence, provided he or she is above the minimum driving age. Countries with the lowest driving ages (17 and below) are Canada, El Salvador, Iceland, Israel, Malaysia, Australia, New Zealand, the Philippines, the United Kingdom (Mainland), United States and Zimbabwe. In several jurisdictions in the United States and Canada, drivers can be as young as 14.
Driver's licenses in the United States
Driver's licenses issued in the United States have a number or alphanumeric code issued by the issuing state's department of motor vehicles (or equivalent), usually show a photograph of the bearer, as well as a copy of the bearer's signature, the address of the bearer's primary residence, the type or class of license, restrictions, endorsements (if any), the physical characteristics of the bearer (such as height, weight, hair color and eye color) and birth date. No two driver's license numbers issued by a state are alike. Social Security numbers are now prohibited by federal law from appearing on new driver's licenses due to identity theft concerns. In most states, to be compliant with AAMVA standards, the orientation of a driver's license for persons under the age of 21 is vertical while a driver's license for those over the age of 21 is horizontal. Since the driver's license is often used as proof of a person's age, the difference in orientation makes it easy to determine that a person is legally allowed to purchase or consume alcohol (the drinking age in all U.S. states is 21). Some states, however, do not require that a driver's license is changed to horizontal, such as Arizona, where it is optional to change to a horizontal license. Furthermore, the vertical license does not expire until age 65 in the state of Arizona. Most states require that when a driver establishes residence in a state, he or she must obtain a license issued by that state within a certain time frame.
