Police dealt with 46 drivers for mobile phone offences during a five-day operation on the M1, including four HGV drivers.
Officers travelling in an unmarked HGV spotted motorists calling, texting, using navigation apps or otherwise interacting with their phones between 12 and 16 October.
A total of 101 drivers were pulled over during the operation.
Nottinghamshire Police said many of those dealt with for phone offences had been using maps and navigation apps, with devices either held in their hands or secured in cradles.
The force warned drivers to mount phones appropriately and avoid interacting with them during journeys. Having a phone secured in a cradle does not prevent a driver from being prosecuted if its use distracts them from the road.
Police said drivers caught holding and using a mobile device at the wheel face six penalty points and a £200 fine. Those distracted by a mounted device could face prosecution for offences such as driving without due care and attention.
Sergeant Jim Carrington, of the Roads Policing Team, said:
“The good news is that more and more drivers now understand that holding a mobile phone at the wheel is not acceptable.
“The bad news is that there are clearly others out there who think they can interact with a device held in a secure mount.
“As several drivers have just found out to their cost, that is simply not the case, because if you are searching for an address or looking for an alternative route, you are not paying proper attention to the road in front of you.
“The same goes for searching for a particular song or skipping the adverts in your favourite podcast.
“Both actions may seem innocuous, but they can each have catastrophic consequences for you and other road users.”
