Motorcycle surveys : headlights, helmets and engine capacity checks.

Two motorcycle surveys have been conducted in 1979, one in summer-time the other in winter-time. In both surveys daytime headlight use was checked and in the latter survey type of helmet and c.c. rating of the motorcycles was also checked. Riders of higher powered motorcycles were more likely to be wearing full-face helmets and using their headlights, while riders of low powered motorcycles were more likely to be wearing "Jét" helmets and not have their lights on.
