     In Britain you're allowed to drive a car when you're seventeen.You have to get a special two-year

driving license before you start.When you're learning,  someone with full license always has to be in the

car with you. You don't have to go to a driving school --a friend can teach you. The person with you

isn't allowed to take money for the lesson unless he's got a teacher's license.

    Before you're allowed to have a full license, you have to take a driving test. You can take a test in

your own car, but it has to be fit for the road. In the test, you have to drive round for half an hour and

then answer a few questions. If you don't pass the test, you're allowed to take it again a few weeks later

if you want to.  In 1970, a woman passed her fortieth test after 212 driving lessons!    ,

    When you've passed your test, you don't have to take it again, and you're allowed to go on driving

as long as (只要) you like, if you're healthy.  Britain's oldest driver was a man who drove in 1974 at

the age of 100.

     Before 1904, everyone was allowed to drive, even children. Then from 1904 car drivers had to have

a license.  But they didn't have to take a test until 1935. In the early days of car driving, before 1978,

cars weren't allowed to go faster than four miles an hour, and someone had to lead the car with a red

flag.
