Petition Review traffic signal colours to ensure they meet needs of the colour-blind

The Government should review the traffic signal colours, the highway code and signal standards to ensure meet the needs of the colour-blind. Traffic signals have used red for stop, red and amber to prepare, green to proceed if safe to do so, and amber to stop unless unsafe to stop.

More details

8.3% of males and 0.5% of females have some sort of colour-blindness. The most common form - deuteranomaly - is red-green colour blindness, which can render two of the three colours on traffic signals less visible. Red appears as a dark-yellow which is more difficult to see than the amber signal which may result in drivers of vehicles not seeing stop signals. This is surely unsafe for all road users - including pedestrians - and makes such drivers more vulnerable to committing driving offences.
