    Globally, road traffic crashes kill about 3000 people a day.1 Identification of modifiable risk factors is an important step in reducing this burden. Previous research suggests that white or light coloured cars are less likely to be involved in a crash, than cars of other colours.2 We investigated the effect of car colour on the risk of a serious injury from a crash, using a population based case control study designed to identify and quantify modifiable risk factors.

    Participants, methods, and results

    The Auckland car crash injury study was conducted in the Auckland region of New Zealand between April 1998 and June 1999.3 4 The study population comprised all drivers of cars on public (urban and rural) roads in the region. Cases (n = 571) were all car drivers involved in crashes in which one or more of the …
