What colour should the new light on traffic lights be?
That's the question that the UK Highways Agency will be putting to the public next month, as it prepares to unveil the new four-light traffic lights that will gradually be rolled out to replace existing signals.
For some time now, safety campaigners have been pressing for a fourth light on traffic signals, to eliminate the false starts and 'queue shuffling' of impatient drivers waiting at red lights.
The fourth light will let drivers know when it's their turn next, so that they can finish picking their nose, changing CDs or applying makeup and be ready to move off in good time.
Wide selection of colours
Motorists and traffic light enthusiasts will be able to vote online at the agency's website, where they will choose from a wide selection of colours and shades.
A winner will then be selected from the five most popular choices via a phone vote, to be televised live by the BBC as part of a star-studded spectacular later this year.
