What's the minimum distance from which an approved driving instructor (ADI) must be able to read a number plate that has letters and figures 79 mm high and 50 mm wide?
Explanation
"There's an eyesight test for the Register of Approved Driving Instructors. The requirement is that an instructor must be able to read a number plate with letters and figures 79 mm high and 50 mm wide at a minimum distance of 26.5 metres (87 feet). This is a greater distance than the minimum legal requirement for car drivers."
