Use your indicators when turning. Always, always use your turn signals to indicate where and when you’re going to turn. This gives other drivers time to react — making it both the safest and most courteous thing to do. Signal as soon as you decide that you would like to make a turn, then look for a space into which to make the turn, not vice versa. This gives other drivers more time to notice you, and perhaps even open up a space for you.
These rules also apply when you are changing lanes, as suddenly switching lanes without giving the drivers around you advanced warning can be very dangerous. Turns into traffic (for example, left turns in right-hand-drive countries) are especially hazardous, and should be avoided if possible. Plan your trip to make turns with the traffic whenever possible.
In London the term minicab is used to refer to a private hire car and “private hire” is used in the rest of the United Kingdom; that is a car with a driver available for hire only on a pre-booked basis. They began operating in the 1960s in competition with hackney carriages after a loophole in the law was spotted (although in some areas it is possible to hold a dual hackney/private hire licence). A minicab must be booked, for example, by telephone, internet, or fax, or in person at the registered minicab office. A minicab can be booked at the time it is required, but only at the office of a company registered to accept bookings rather than directly with a driver.
