Two drivers have been caught on camera doing 133mph near Grantham, new figures show.
The drivers were spotted by a speed camera on a stretch of the A1 in the last 12 months – and one of them was a police officer.
One driver used a cloned number plate to fox the camera and get off while it is understood the police officer was authorised to break the 70 mph national speed limit in the course of his duties.
The details emerged following a Freedom of Information request by the Sleaford Target.
While the officer escaped prosecution, Lincolnshire Road Safety Partnership spokesman John Siddle said officers went through the same procedure as members of the public when a speeding office had been committed.
He said: “There are officers walking around with points on their licence. The process for officers is the same as normal.
“The driver would be identified and we then find out if the driver was authorised to do that speed.
“If they were not, then the process is the same as it is for everyone.”
The two Lincolnshire drivers were still short of the highest recorded speed on roads in England and Wales between April 2013 and May this year.
A motorist on the M25 at Swanley holds the record for the highest speed clocked by a speed camera.
The driver managed to reach a speed of 149 mph.
