More than 100 drivers were stopped in just five days as police officers drove a lorry in an attempt to find the "ideal vantage point" to catch criminals.

Norfolk Constabulary's Operation Tramline involves officers driving "HGV tractor units" to look directly into lorry cabs and on to offending motorists.

Between October 21 and October 24, officers patrolled the A47 and A11 and stopped 101 vehicles, detecting more than 120 offences.

They focused on drivers not wearing their seatbelts or using a mobile phone.

Once identified supporting officers in regular cars would then pull over any offenders.

Of the 101 vehicles stopped, 18 were HGVs, 45 were LGVs and 38 were private goods vehicles.

The offences included 26 drivers not wearing a seatbelt, nine using a mobile phone, and four for speeding.

Officers then issued 86 Traffic Offence Reports and arrested one driver.

Sgt Ade Hales, of the joint Roads and Armed Policing Team, said: “We have been telling drivers to wear a seatbelt for over 40 years, so it is shocking to see such a high volume of drivers still failing to do so.

"It is an action which takes seconds and ultimately could save your life.

“I am thankful for the support of National Highways who enable us to complete such operations.

"We will continue to work to raise awareness and educate the public about the risks surrounding dangerous and distracted driving.”
