Interesting Fact - Driving

To pass your driving test in the UK, you must be able to read (with glasses or contact lenses, if necessary) a car number plate made after 1 September 2001 from 20 metres.

(In addition, you must also meet the minimum eyesight standard for driving by having a visual acuity of at least decimal 0.5 (6/12) measured on the Snellen scale (with glasses or contact lenses, if necessary) using both eyes together or, if you have sight in one eye only, in that eye.  But as I mentioned earlier, you don't have to have a regular eye test, which accounts for all the old codgers, driving at 10mph craning over the steering wheel.)
