Almost 25,000 drivers were caught speeding in Gloucestershire last year, figures reveal.
Speeding accounted for more than nine in 10 driving offences in the country last year.
The transport research charity RAC Foundation says the simple rule for drivers who want to avoid a speeding ticket is to stay within the limit.
Analysis of Home Office data by the group shows that motorists were caught driving too fast 24,121 times by Gloucestershire Constabulary in 2018-19.
It means 94 percent of the 25,729 motoring offences recorded over the period were for speeding.
Steve Gooding of the RAC Foundation said: “The simple rule for drivers who don’t want to risk ending up with a speeding ticket is not to break the limit in the first place.
“Where limits are properly signposted, and clearly feel right for the road in question, then motorists have no excuse for going faster.
“But that means highway authorities also have a responsibility to make sure the limits they set are appropriate and to avoid instances where the limit repeatedly bounces up and down along a single stretch.”
The number of speeding offences detected in Gloucestershire in 2018-19 was 11 percent higher than during the previous year, and more than double that during 2011-12.
54 percent of speeding offences in 2018-19 were dealt with by sending the driver on a speed awareness course.
The next most common outcome was a fine (36 percent), while 6 percent resulted in court action and 3 percent of offences were cancelled.
The analysis was carried out with Liverpool John Moores University.
