The government produces a Highway Code that details the requirements for all road users, including drivers.
Road signs in the UK use imperial units, so speed limits are posted in miles per hour.
On some motorways a lane is provided on the left hand side referred to as the 'hard shoulder', which should only be used when a vehicle has broken down.
There are two broad categories of pedestrian crossing to aid the safe passage across major roads by those travelling on foot.
Drivers from the USA, however, must take a British test if they wish to drive in the UK for more than a year after arriving in the country (with the exception of US military personnel stationed in the UK for a set period of time are allowed to drive on their US licence After completing their third Air Force licence training course.).
However driving licences from the European Union, Norway, Iceland, Liechtenstein and Switzerland are valid in the United Kingdom.
