British car registration plates?

Question

Why are they white on the front and yellow on the back?

Answer 1

they are yellow on the back so they stand out more in other car headlights.and they are more speed camera friendly to.

Answer 2

The ideal for clear legibility is black lettering on a white background, as used at the front.

However the plates are reflective, and it is illegal under UK law to show any white light source (a light, or a reflector) at the rear other than a reversing light. This makes a white reflective number plate illegal at the rear, so another colour had to be chosen. Yellow was next-best for legibility.

Answer 3

allan_j's got it. In an ideal world it'd be white on the back too (it reflects better) but in this country you're not permitted to show white to the rear except reversing lights. That includes reflectors.

Answer 4

So you can tell in the dark whether the front or the back of the car in front is facing you, handy to know on a foggy night.

Answer 5

basically its to do with any light source at the rear musn't show white light hence the use of yellow.

Answer 6

because the yellow is reflected and it can be seen in the dark

Answer 7

The white indicates the vehicle is coming towards you (that also goes for headlights and reversing lights)

Answer 8

so that you can tell which way a car is facing when it's dark and you only have the reflection to go by



.

Answer 9

We have become so pollitically correct that we cannot discriminate against yellow so we have to have white as well.

Answer 10

reflective and yellow so that you may be seen from the rear
