Reflective number plates were introduced to the UK in the late 60's early 70's The reasoning behind the white/yellow colouring is so that you could tell which way a vehicle was facing, in poorly lit areas. White, it was coming towards you, yellow it was facing away from you.
Why are English car number plates white on the front and yellow on the rear?
why are car number plates yellow at rear and white at front
there is no restriction on the material used however it must be of a reflective material and white in colour for the front and yellow for the rear. Not all plates are Yellow front and White rear. For example German plates are embossed metal. The new french plates are printed.
Depends on where you are. In the UK, Yellow license plates are used on the rear of a car and white ones on the front. They are both retroreflective to aid visibility and conform to standards that allow ANPR (Automatic Number Plate Recognition) by the police.
Check yellow pages or is it white pages

No, the white line is for your front bumper. If your front bumper passes the white line on yellow, that's just going through a yellow light, which isn't illegal. You can call it a close call, but not illegal.

A yellow no plate of a car is indicate that the car is use as a taxi but a white no plate is stand that it is use for personal use.
Two reasons:If you see a car at night that doesn't have lights on, it's easy to tell which way the car is facing by the number plate colour.It is illegal to show a white light to the rear of a vehicle (again, so people know which way your car is facing) - white number plates would reflect white light.
