Police stopped dozens of HGV drivers as part of a campaign to improve motorists’ safety on the region’s busiest roads.
County officers went out on Sunday to focus on the M1 from Junction 15 up to Junction 2 of the M6.
It was part of a six-day regional operation to crackdown on HGV drivers breaking the law by speeding, using mobile phones while driving, not wearing seatbelts and drinking and driving.
Police detected 45 offences, including three for no insurance, 38 for driving without wearing a seatbelt, three for driving while using a mobile phone, and two for not displaying a valid number plate.
Superintendent Andy Cox, head of specialist operations, said: “Making our roads safer is one of the force’s top priorities.
“This was part of a Fatal Four campaign to tackle speeding, mobile phone usage, not wearing a seatbelt and drink driving.
“The force is committed to reducing the number of these offences through enforcement, education and communication.”
