A new study from the Society of Automotive Engineers has concluded that failure of drivers to use turn signals could be responsible for as many as 2 million accidents every year.

A new study from the Society of Automotive Engineers has concluded that failure of drivers to use turn signals could be responsible for as many as 2 million accidents every year. And surprisingly, this is more than twice the number of auto accidents attributed to distracted driving, including texting while driving.

According to the research, drivers incorrectly use turn signals when changing lanes 48% of the time. Drivers also fail to use their turn signal about 25% of the time when actually making a turn. In total, the research estimates that turn signals are used improperly 750 billion times a year.

The author of the report notes that drivers have a duty to use their turn signals in much the same way that drivers have a duty to stop for stop signs and red lights. And while we’ve all seen numerous drivers who believe they don’t have a duty to stop for stop signs and red lights either, we’ve seen many more drivers who simply won’t use a turn signal.
