This leaflet discusses the risk of information overload and its effect upon drivers in the UK. It is considered that drivers can concentrate on five plus or minus two pieces of information at a time. These may include traffic news on a radio, satellite route guidance systems, and over-complex road signs with different messages. It is claimed that the effects of information overload can harm concentration more than marijuana, with men twice as likely to be distracted than women. Proliferation of road signs is considered a particular hazard. An example of a junction on the A3 at New Malden with 17 different signs is discussed. Road sign proliferation is considered a particular eyesore in rural areas. Clear, concise and legible signs which are timely, appropriate and relevant are considered essential. Better advance signing could prevent collisions at junctions. It is also suggested that drivers should make more effort to improve their understanding of road signs.
