Benovians set their clocks back an hour for the winter. The result is that, during winter`s short days, it is light when most commuters drive to work, but dark when they drive back home. Darkness contributes to accidents. Changing the clocks, however, does not actually increase the amount of driving done in the dark, so it is unlikely to have any effect on Benovia`s automobile accident rate.
