DRIVERS caught breaking 20mph zones by 4mph in the city will from today face a fine and points on their licence.
Those found to be driving at 24mph through speed restricted areas in Oxford could end up paying a £100 fine and find themselves with three penalty points.
Thames Valley Police will offer a £95 speed awareness course as an alternative.
The 24mph enforcement action has only started now because police staff in the roads policing team have been trained to deliver a three-hour course on the importance of honouring the 20mph limit.
Most of Oxfords roads were made 20mph zones from September 2009 in a £250,000 move by Oxfordshire County Council.
But police initially admitted they would not enforce them.
It was not until three years later, in 2012, that police started to issue fines for speeding in the designated streets.
Those travelling between 26mph and 31mph were given a verbal caution, while those travelling at 32mph and above were given fixed penalty notices of £60, plus three points.
