Saudi Arabia is easing restrictions on women driving, finally allowing almost half its population to get behind the wheel. A royal decree has been issued that will allow women in the country to drive, the Saudi Foreign ministry said Tuesday. The government will have until June 24, 2018, to implement the new decree. Manal al-Sharif, one of the women behind the Women2Drive campaign, celebrated the victory by posting a photo on Twitter of herself behind the wheel of a car. Sharif, who now lives in Australia, was jailed in Saudi Arabia 2011 after posting a video on YouTube of herself, wearing a black headscarf and sunglasses, driving a car. The act provoked death threats and spurred her to start the campaign. Liesl Gerntholtz, executive director of the Women's Rights Division at Human Rights Watch, told CNN while it was a "very important step" there was still a long way to go for Saudi women. "This prohibition on driving is just one in a vast series of laws and policies which prevent women from doing many things," she said. "The guardianship rule stops women from making every decision in her life without the assistance of a male relative, even if that relative is her 7-year-old son. The Kingdom of Saudi Arabia follows a strict form of Wahhabi Islam that bans the mixing of sexes at public events and places numerous curbs on women. These restrictions are enforced by religious police.
