Familiarity and understanding of traffic signs are an integral part of the theory and practical driving test. The Department for Transport last published research on understanding of traffic signs in March 2004 in a report entitled ‘Increasing Understanding of Traffic Signs’. The research considered a limited number of traffic signs and did not provide detailed analysis by road user category.
A further research project has been agreed to inform the ongoing traffic signs policy review. This will include detailed analysis by road user category. We plan to commission this work later this year.
