Does vehicle size, environmental light, or weather inluence accident rates?


Vehicle related variables should also include vehicle type (car, van,
ambulance, truck, bus or other) and year since the vehicle was first
registered for driving on public roads. We believe that vehicle size is an
important factor, since it is recommended that vehicles such as
schoolbuses, patrol, emergency, and firefighting vehicles use yellow or
white colours.

Furthermore visibility conditions depend on environmental light
(daytime, twilight or night), and weather conditions (good weather, light
fog, thick fog, light rain, heavy rain, hail, snow or strong wind).

Therefore it would be very important if the authors could provide
data about the effect of vehicle size, environmental light, or weather on
the results of their study.
