The 31-year-old singer will be given a complimentary six-seater cab with blacked-out windows and room for her entourage by online taxi service GetTaxi, reported Daily Star.
"We can sympathise with Sarah being instantly recognisable and hassled by the public," Roy Manor, managing director of GetTaxi, said.
The singer was spotted talking on the phone while driving on Charing Cross Road, central London on April 4 and a drving ban was imposed on her.
