Pollono said Friday that he is protesting the decision, saying a veil is no different from a motorcycle helmet in terms of hindrance to vision.
The driver gave a news conference Friday -- while wearing the niqab veil, which covers the entire face except for the eyes -- and expressed "a feeling of injustice" over the incident.
"I didn't commit any infraction," said the driver, who declined to give her name. "I see just as well as you ... I have driven like this for nine years. I've not had any problems."
The driver is French by nationality. The lawyer said she had never been stopped until now, after months of recent parliamentary discussion and government talk about possibly banning the veils.
President Nicolas Sarkozy raised the stakes Wednesday in France's drive to abolish the all-encompassing veil, ordering a draft law banning them in all public places. He insists the veils oppress women, and decided to defy France's highest administrative body, which says such a full ban could be found unconstitutional.
When the driver was stopped, the traffic police asked her to raise her veil to confirm her identity, and she complied, Pollono said.
"A French citizen cannot be fined based on the way he or she dresses," Pollono said. "If the veil is forbidden behind the wheel, then nuns should not be able to drive, and full helmets for motorcyclists should be banned, because you can't see on the sides, and even some police units who drive with masks should be fined."
Sarkozy's move angered Muslims in the Arab world and worried Muslims in France, who fear they are being stigmatized because of a very small minority of women in France who cover their faces with niqabs or burqas.
A leading French conservative lawmaker who has been at the forefront of the push against the veils, Jean-Francois Cope, has been given police protection, officials said Friday.
Cope has had a security officer accompanying him since January, said two officials who spoke on condition of anonymity because of the sensitivity of the situation. In January, Cope, head of the governing conservative party UMP in the lower house of parliament, submitted a proposed bill on banning the veil. The officials would not comment on a report in the French daily Le Parisien that Cope had received threats.
French officials have cited a concealed face as a security risk. Belgium also is considering a ban, and some Muslim countries have also struggled with how to deal with the face veils.
France has western Europe's largest Muslim population, estimated at least 5 million. The French parliament outlawed Muslim headscarves and other "ostentatious" religious symbols from classrooms in 2004.
