Two female drivers were stopped Saturday morning on the Taif-Riyadh road as they and their families headed for the Western Region, officials said. Road patrols stopped the two cars with Omani plate numbers after they received a tip and spotted the women driving; a man reported that he saw someone throw a water bottle from one of the cars, pursued the vehicle and saw the women driving, according to officials. Patrols at the Jisr Ashira checkpoint at Taif's eastern entrance stopped the two cars, the two women and their fathers were asked to sign an undertaking after they said they were unaware of regulations and they were allowed to leave with their male companions driving, officials said. A security official said that in such cases, a violation is recorded and an undertaking is signed that the woman does not drive in the Kingdom again. In recent weeks, some Saudi women, including Wajnat Al-Rahbini, an actress, and Manal Al-Shareef, were arrested in the Eastern Province and Jeddah for driving. Authorities in the Kingdom say the issue of women driving is a decision of the society. __
