Motorists are in danger of crashing because of an inability to decipher all the information that is thrown at them on their journeys, according to the RAC Foundation.

It claims clutters of contradictory signs lead to confusion that can result in collisions.

Information overload' means motorists can miss important information.

Driving in a rural area with traffic news on the radio, instructions from Sat Nav, over complex road signs with four different messages, means we may miss the flood' sign. We may see it but not take it in. We then end up in deep water.
