Police focus on truckers' driving in South Yorkshire
Hundreds of lorry drivers across South Yorkshire have been monitored as part of a week-long campaign.
South Yorkshire Police (SYP) have for the first time used a large goods vehicle to patrol some of the county's busiest roads and motorways.
Drivers caught using mobile phones and electrical devices have been pulled over by the police.
SYP said the crackdown, which began on Monday, had "uncovered a wealth of danger."
The lorry travelled across some of South Yorkshire's busiest roads, including the M1, M18 and A1.
The HGV was chosen because officers felt it gave them a different viewpoint to detect offences being committed.
When a crime was spotted or police had concerns, a patrol car stopped the offending driver.
Officers said that they have stopped more than 50 vehicles in a week.
A variety of offences were uncovered, from incorrect paper work to one driver who was caught driving with his foot on the dashboard.
Head of SYP's Operational Support Services, Ch Supt Keith Lumley said it had seen "significant successes since the operation began" and would make the "roads safer for every motorist.
"Any vehicle that is not being driven correctly can be a lethal weapon - especially large vehicles being driven at speed."
The force are the second to use this method in the country, were the original idea was developed by West Midlands Police who trialled the technique last year.
SYP hope to use the HGV vehicle in the future.
