The aim of the present report is to discuss the importance of the driver's hearing ability when driving, and to decide whether it is necessary to make requirements regarding this ability when licencing the driver. Investigations on the relationship between hearing ability and accidents show conflicting results, and have methodological shortcomings which make it difficult to reach a reliable decision. Another method is to evaluate the importance of noise and signals in a theoretical manner. It is concluded that hearing has minor importance for safe driving. Besides, the number of drivers in Norway who are deaf or have considerably reduced hearing ability will probably be fairly low, about 500 to 700 persons. Accordingly it is recommended that requirements should not be made on driver's hearing ability. However, drivers who are deaf or have a considerably reduced hearing should use extra mirrors on the vehicle to increase the possibility of using their vision. /TRRL/
