The importance of good visibility of the road scene is discussed in relation to (a) visibility from the driver's seat, and (b) how clearly vehicles, rear lights, and signalling lights can be seen. Suggestions are made for additional arrangements of lights to assist in fog and in following in queue conditions. Methods by which direction indicator lamps could be made more efficient are noted.
It is concluded that, in the design of a vehicle, there is a need to study the conflicts that arise between good visibility and other safety factors.
