More than half of women who drive in the U.S. are women, according to a new study from the National Center for Health Statistics.

While the gender gap has narrowed over time, it is still substantial.

The number of female drivers has grown steadily since the mid-1980s, and today the number of women in the workforce is nearly twice as large as the number who are drivers.

The numbers are even larger for men, who are now responsible for roughly half of all crashes in the United States.

In addition, the numbers for women are likely to be higher because of the higher rates of alcohol use, which are more prevalent among women.

“Women have to be conscious of how they use their bodies when they’re driving,” said Lisa M. Miller, a doctoral student in the department of sociology at the University of Colorado Boulder.

“You need to be mindful of the body language of your body when you’re driving and you need to pay attention to what the other drivers are doing.

It’s not just that you have to pull over to the side of the road.

You have to also pay attention.

It can be very hard to do.

You’re just in a situation where you have no control.

You’ve got to be attentive.”

Miller is the lead author of the new study.

She has previously published research that suggests women in this age group are more likely to have problems with alcohol use and to have trouble getting to work.

The new study, published online in the journal Health Psychology, also looked at the risk factors for car crashes, which includes driving habits, medical history and driving history.

Miller’s research team analyzed data from nearly 5,000 drivers who were involved in crashes in California between 1990 and 2014.

Of those, about half were female and the rest were male.

Miller and her team then compared those drivers’ crash rates to drivers who weren’t in crashes and to drivers with and without a history of alcohol and/or other drug use.

They found that women were more likely than men to have a history and a higher likelihood of alcohol or other drug abuse.

Women were also more likely at risk for other types of crashes, including accidents involving alcohol and drugs.

The women with higher crash rates were also about twice as likely to report driving while impaired, which included driving while under the influence of alcohol, and more likely for their blood alcohol content to be .07 or more.

In contrast, women with lower crash rates reported driving when impaired, and the men who had lower crash rate were more than twice as many as the men with higher collision rate.

“We saw some very different findings,” Miller said.

“Women who reported driving while drunk had higher crash rate, but those women were also significantly more likely with a history.

Women with a DUI had lower collision rates than those with a DUIs, but they were also almost twice as often as women with no alcohol or drugs.

That suggests that alcohol and drug use may be a more important risk factor for crashes in women than it is in men.

We can’t say that women are more or less likely to drive than men, but the differences are there.”

Miller and colleagues are working on a follow-up study that will look at the relationship between crash rates and medical history.

In that study, they are also examining drivers’ driving histories and driving behaviors.

Miller is hoping to examine the impact of various driving strategies on crashes.

For example, if the female driver has been involved in a collision in the past and has a history, her odds of crashing could be higher than the male driver.

Miller said the new data also may help researchers better understand why some drivers may be more likely or less willing to crash than others.

“There’s some evidence that the female drivers who have more problems are the ones who have been drinking,” she said.

Miller also said the research may also help identify ways to improve safety for women.

She said it may help if more people started driving more responsibly and encouraged them to follow traffic signals, which she said should be a priority in the future.

“We also have to look at how to improve the quality of our driving and how to reduce the number and severity of accidents that occur,” Miller added.
