(AFP) -- King Salman last month decreed that women will be allowed driving permits, a historic reform that could put not just millions of women behind the wheel but potentially many more into the workforce.

Sensing a lucrative opportunity, ride-hailing company Careem says it plans to hire up to 100,000 female chauffers to lure new clients in the gender-segregated kingdom.

This week, the company invited AFP to its first recruitment session in the coastal city of Khobar, which attracted a diverse crowd -- from housewives to working women -- who already have foreign driving licences.

"For years I felt helpless. My car would be parked outside and I could not drive," said Nawal al-Jabbar, a 50-year-old mother of three, sipping coffee from a thimble-sized cup.

A chorus of hoots and claps erupted in the auditorium as the women, who learned about the recruitment by word-of-mouth, watched news footage on a projector screen of last month's royal decree.

"It felt like we had woken up in a new Saudi Arabia," Jabbar said.

An instructor stood next to the screen, holding up a smartphone to show the inner workings of the app.

The firm plans to add a new "Captinah" button to the app next June that would allow customers to choose women chauffeurs. The option will only be available to other women and families, Careem spokesman Murtadha Alalawi said.

Around 30 women registered for the event in Khobar.

Many arrived unaccompanied by men, something not commonly seen in a country where male "guardians" have arbitrary authority to make crucial decisions on behalf of women.
