Speed limits: The UK still uses the imperial system for road signs. All limits and restrictions are set in miles per hour (1 mile = 1.61 kilometres) and yards (1 yard = 0.91 meters). Knowing the national generic limits for cars and motorbikes will make life a lot easier, so you don’t have to convert in your head while driving. On UK roads, it is unusual to find speed limit signs unless the speed limit differs from the “standard” limit for that road type.
