Undercover traffic police will ride along busy roads in a bid to crackdown on motorists who overtake too close to cyclists.
Any driver spotted getting too close will be picked up by fellow officers waiting in marked cars, under a new scheme being launched by Hampshire police.
The initiative has been run at West Midlands Police and is set to be rolled out by officers in the county soon.
In the midlands 130 drivers were pulled over in nine outings. Eight have been prosecuted for careless driving. In some cases, camera evidence was used to prove how close drivers had come to a cyclist.
Drivers were offered education at the roadside, but repeat or serious offenders were prosecuted.
The move has been welcomed by cyclists across the area.
Last year it was revealed that the Portsmouth area was ranked the highest for casualties in four out of the past five years – with the highest levels of casualties per million of the population coming in 2011 with 983. In 2015 there were 888.
Hampshire roads policing officers went to a training day with West Midlands Police on the initiative which a force spokeswoman said was ‘both interesting and informative’.
Chief inspector Henry Parsons, of the Joint Operations Roads Policing Unit, said: ‘The "close pass" initiative looks excellent and we are making preparations to use it across Hampshire Constabulary and Thames Valley Police areas.
‘A launch date is anticipated soon.’
