More than 60 women across Saudi Arabia claimed they drove cars Saturday in defiance of a ban keeping them from getting behind the wheel, facing little protest by police in their push for easing restrictions on women in the kingdom.

The campaign’s message is that driving should be a woman’s choice. The struggle is rooted in the kingdom’s hard-line interpretation of Islam known as Wahabbism, with critics warning that women driving could unravel the very fabric of Saudi society.

Though no laws ban women from driving in Saudi Arabia, authorities do not issue them licenses. Women who drove on Saturday had driver’s licenses from abroad, activists said.
