A firm selling speed camera detectors which could be outlawed is threatening to sue the Government for compensation on behalf of its customers.
Speed camera detectors would be outlawed under proposed legislation
Car Parts Direct, with branches in Mansfield and Derby, has sold 10,000 of the £200 Quintezz radar devices.
The Transport Bill, to be debated by MPs next week, could see a ban on all equipment that scans for speed traps.
Company owner Mark Cornwall said: "We are not going to stand by and watch this happen."
He told BBC Radio Derby that roads are safer if people use speed camera detectors making them slow down around camera locations.
He said: "If the Government manage to ban our radar detectors then speeding ticket fines will rocket.
"More and more motorists will lose their driving licences and be without the means of earning an income."
Mr Cornwell said the firm will stand up for drivers trying to keep within the law.
