why are car number plates yellow at rear and white at front
Why are English car number plates white on the front and yellow on the rear?
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.
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.
Acrylic number plates sigify the registration mark of a vehicle. Currently the UK regulations insist on a yellow rear plate unless the vehicle is a classic car and can display black and silver plates. They can be made of different materials, but more commonly seen are metals and acrylics. http://www.image-reg.com/acrylic-number-plates.html
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.
