The Institute of Advanced Motorists (IAM) has revealed that more than 17,000 people have been convicted of careless driving offences since police were given the power to issue fixed penalty notices for it two years ago.

The figures come from a Freedom of Information request by the IAM to every police force in England and Wales.

The statistics cover the two years from August 2013 to August 2015. A total of 17,468 people were convicted of this charge in this time period.

Some 33 out of 43 police forces responded to the IAM’s request. The force area with the highest number of people convicted:

  1. Essex (3,630)
  2. Humberside (1,998)
  3. Nottinghamshire (1,139)
  4. Derbyshire (949)
  5. Hampshire (929)

On 16 August 2013 police were given the power to give on-the-spot penalties for drivers who put other road users’ lives at risk for offences such as tailgating and poor lane discipline.

The remainder of the top 12 overall numbers of people convicted according to police force area were:

6. Thames Valley: 924
7. Surrey: 830
8. West Yorkshire: 804
9. Cheshire: 720
10. Greater Manchester: 607
11. Lancashire: 578
12. Dyfed-Powys: 440

Sarah Sillars, IAM chief executive officer, said: “While these offences fall under the lower end of the scale for motoring transgressions, such driving behaviour could easily have caused a serious accident.

“Tailgating is an aggressive action designed to intimidate another driver, while unpredictable lane-changing is both thoughtless and dangerous.

“We hope these on-the-spot fines and remedial courses have helped concentrate the drivers’ minds and make them think twice about these potentially hazardous manoeuvres in the future.â€

In the case of Essex with the highest number of people convicted 2,958 of them undertook a course, 484 went to court and 188 took a conditional offer.

In Humberside, the second highest area 1,469 attended and completed a retraining course and 364 have been put forward for consideration for court prosecution.
