Police from three communities in southwestern Connecticut set up checkpoints on Monday looking for distracted drivers.
Officials were looking for people who were texting, talking on the phone or using a handheld device while driving.
The joint operation was organized by the Norwalk, New Canaan and Wilton police departments.
According to some studies, drivers will look down for more than four seconds when reading or sending a text. That's enough time to travel the length of a football field while going 55 mph.
The fine for a first offense is $150. Some police officials say that's not high enough given the seriousness of distracted driving.
According to the government, 3,300 people were killed in distracted driving crashes in 2012.
