As daylight savings time changes go into effect and clocks are brought one hour forward, a new study finds that there may be some benefits to pedestrians and bicyclists as accidents involving these road users are reduced after the change. The same benefits, however, do not extend to motorists.
The effect of daylight savings time change has been analyzed by traffic safety experts several times in the past. In this most recent study, the Insurance Institute for Highway Safety researchers analyzed traffic accident data from between 2010 and 2019. They further divided these accidents based on the hours around the time change – between 4:00 a.m. and 10:00 a.m. and 3:00 p.m. and 9:00 p.m. – and further divided these accidents based on whether these involved motorists or pedestrians and bicyclists.
The data found that the overall net effect of the time change was minimal, regardless of whether the accident involved pedestrians and bicyclists or occupants of a passenger vehicle. However, about 5 weeks after the fall time change went into effect, they found that there was an increase in the number of car accidents involving bicyclists and a drop in the number of auto accidents involving motorists. Conversely, when they analyzed the data from about 5 weeks after the spring time change went into effect, they found an increase in the number of auto accidents involving motorists and a drop in the number of accidents involving pedestrians and bicyclists.
