Authorities say three separate traffic stops on Interstate 80 netted a total of 55 pounds of marijuana and led to drug charges against five people.

The Nebraska State Patrol says 6 pounds of pot were seized when a trooper stopped a car for speeding in Hamilton County on Monday. The driver was arrested.

On Saturday, troopers found 10 pounds of marijuana after stopping a vehicle for failure to signal at an exit in York County. The driver and a passenger were arrested.

Last Friday, officials say 39 pounds of marijuana and 2 pound of hashish were found when a trooper stopped a car for following too close near the Lincoln Airport exit in Lancaster County. The driver was charged.
