Millions more women are taking to the road, while driving among men in their 20s is on the decline.
The number of women holding driving licences rose 14% between 1995 and 2010, a travel trends report revealed.
But over the same period, driver licence-holding among men aged 20-29 dipped 14%.
The biggest increase in women drivers has come in north east England, said the report which was co-sponsored by the RAC Foundation, the Office of Rail Regulation, the Independent Transport Commission and Transport Scotland.
The average distance women drove rose 22% between 1995 and 2010, with - again - the biggest rise being in the North East.
Women also contributed to the big growth in rail travel during the same period, according to the report .
In mileage terms, rail passenger travel increased 54% between 1995 and 2010, with the women passenger rate rising 86%.
In the same period, company car mileage - mainly a preserve of men - fell 50%.
The report pointed to a number of social trends for the increase in women's travel patterns.
These included women having their first child at a later date on average, more women working and increased life expectancy for women.
