One driver told police he didn’t know how to work his hands-free kit and a HGV driver was caught texting.
Police targeted areas across the Fylde coast from March 1 to mark new penalties for the offece, which is now six points and a £200 fine.
As well as the 77 caught using their phones, a further 53 people were caught travelling without wearing a seatbelt including a driver with two young children in the car.
A total of 52 vehicles were seized from the roadside for a range of reasons including no insurance or no diving licence.
Two hundred speeders were also caught in the same period.
Chief Inspector Damian Kitchen said: “Some of the people caught now face not only increased insurance premiums, but in some cases the potential of losing their jobs. I would rather we catch nobody and see this offence become a thing of the past. This is not about fines and points, it’s about stopping people getting injured on our roads.”
