The Italian government has temporarily taken hundreds of speed cameras out of service, deeming them non-compliant with new rules that came into force on Sunday.

After years of legal uncertainty, Italy's transport ministry has ruled that speed cameras must not only blur the faces of drivers and passengers, but also have a margin of error of less than three percent above 100 kilometres per hour, among other requirements.

Around 3,150 speed cameras have been found to be in compliance and will continue to catch speeding motorists on Italy’s roads.

But manufacturers will have to apply for another 850 to be certified in coming months, the ministry told AFP on Monday.
