A speed-check by officers on the coast saw 30 people caught breaking the limit - including one doing almost double.
On the evening of Saturday, February 13 the Road Casualty Reduction Team oversaw a patrol on the A47 near the James Paget University Hospital in Gorleston.
A tweet posted by Norfolk and Suffolk Roads and Armed Policing said 30 speeders had been dealt with and one driver stopped for having no MOT.
They said: "The highest speed was a depressing 73mph in a 40-limit zone."
