A frequently asked question of Foundation staff is "What is the safest car color?"
Psychological studies show that color has an effect on behavior, and there are other
studies about color and conspicuity, but there are very few studies examining the impact
of car color on crash rates.

In preparing this white paper, very little information was found specifically on car color
and safety. People assume that yellow is the safest color because it is used for school
buses. However, when the National Conference on School Transportation chose the
color at their meeting in 1939, nothing was mentioned about the expected effect on
traffic safety. Similarly, many people think red is a safe and conspicuous vehicle color
because fire trucks are red; again we found no research supporting this belief.

Of the two studies identified that actually sought to test the association between vehicle
color and crash involvement, one found that silver cars were least likely to be involved
in injury crashes (Furness 2003), and the other found that white or yellow cars were
least likely to be struck by other drivers who committed infractions (Lardelli-Claret
2002). The finding that silver cars were safest was contradicted by many anecdotes of
silver being seemingly invisible to other people and to animals, especially against the
sunset.

When choosing a vehicle, the bottom line is that there is presently no scientific evidence supporting the selection of one particular vehicle color as the unambiguous best choice for safety.
