Across the nation, more women now have driver’s licenses than men.

A recent study reported the shift, which flops a longtime gender gap among licensed drivers. This may not be the biggest automotive news since the Model T—but it is the first time since the Model T was released in 1908 that male drivers have taken a back seat to women.

The study, by the University of Michigan’s Transportation Research Institute, evaluated gender trends in driver’s licenses from 1995 to 2010. In 1995, the number of men with licenses was 89.2 million, versus 87.4 million women. By 2010, the numbers showed women ahead by 105.7 million versus 104.3 million men.

According to the report, the share of teens and young adults of both genders who have driver’s licenses is on the decline, and the greatest downward trend is among young men. If this trend continues, the new gender gap could continue to widen.

Future implications for vehicle demand, energy consumption, and road safety could be on the horizon, according to the study, which reports women are more likely to purchase smaller, safer, and more fuel-efficient cards, drive less, and have a lower fatality rate per distance driven. Stay tuned!
