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.
Drunk driving in the United States
Research in the United Kingdom has shown that the danger group for drunk driving is young men in their early 20s rather than teenagers. It is not uncommon for police forces in Australia to randomly stop motorists and submit them to a random breath test. This test involves speaking or blowing into a hand held device to give a reading. Refusing a roadside test is an offense, and is subject to the same penalty as high range drunk driving. This detection method is not employed in the UK, and it is not an offence in England or Wales for a fully licensed driver to drive with a BAC of less than 0.08% (Australia and Scotland have limits of 0.05%). Also in Australia it is an offence for any person driving on Learner or probationary ('P1 or P2') plates (aged under 20 years) to drive with any alcohol at all in their system. The BAC must be 0.00% and still remains under 0.05% for an "instructing a learner".
