A French court has annulled a fine imposed on a woman for wearing an Islamic veil while driving.
In April, police in the western city of Nantes fined Sandrine Mouleres 22 euros (£18; $29), saying the veil she was wearing restricted her vision.
Her lawyer hailed the court's decision to quash the fine on Monday, saying the niqab - which shows only the eyes - did not present a danger.
A public ban on face-covering veils comes into force in France next year.
Proponents of the ban say it will defend French values but critics say it could stir anti-Muslim feeling in France, where Islam is the second religion.
Women who flout the ban face fines of 150 euros, with heavier penalties for those found guilty of forcing women to wear a veil.
Though the fine was small, the case of Ms Mouleres attracted great public interest and gained symbolic importance amid the impassioned debate over banning face veils, correspondents say.
Ms Mouleres's lawyer Jean-Michel Pollono said the fine constituted a breach of his client's human rights.
He argued the niqab moved with the head and thus was not a hindrance to drivers.
"We are in a free country, and as a result, everything that isn't forbidden is allowed," he said on Monday.
"We can now drive with a niqab."
France has Europe's largest Muslim minority population, estimated at about five million. The French interior ministry estimates that only about 1,900 women wear full veils in the country.
There are several types of headscarves and veils for Muslim women - those that cover the face being the niqab and the burka. In France, the niqab is the version most commonly worn.
