A total of 11 motorists were arrested for speeding on the N1 near Midrand on Sunday, Johannesburg metro police said.

Chief Superintendent Wayne Minnaar said an Audi S3 was caught travelling at 212km/h. The car had no numberplates.

Another speeding Audi driver was taken into custody after police found that his vehicle had been using false numberplates.

"The man in his late 60s could not explain how he got the plates. They had been registered to another vehicle in the Western Cape," said Minnaar.

All those arrested would appear in the Randburg Magistrate's Court soon on charges of reckless and negligent driving.
