Another problem is the cost of driver’s education for women, which is four to five times as expensive when compared with what men pay.

Mohammed al-Ghanami, a diving instructor for the Saudi Marines, has been giving his wife lessons in remote areas where the police or other motorists will not disturb them. He moonlights as an Uber driver and wants his wife to be able to drive their child to the doctor or anywhere else in an emergency, given his extended absences.

“She can do it,” he said. “She’s a careful person and a good driver.”

Groups of girlfriends, meanwhile, are making celebratory plans for their first drive. Rezan Ben Hassan, 29, learned when she was 16 on desert camping trips with her family. She intends to take the keys to the family vehicle on Sunday and cruise to a cafe.

In Al Khobar, Ms. Bassem, the motorcycle lover, plans to hit the road with friends from the local Harley Davidson club. Of their roughly 700 members in Saudi Arabia’s Eastern Province, a handful of women love Hogs.

In what appears to be an attempt to dissuade unqualified drivers on Sunday, the Ministry of Interior announced that the police would be fining drivers caught without a license 900 riyals, or approximately $240.

The lack of an official license, however, is not discouraging Ms. Bassem. “This is going to be one of the most exciting days of my life,” she said.
