Two current and two former Massachusetts State Police troopers were among six people charged Tuesday in a scheme to allegedly take bribes including a new snowblower and driveway in exchange for giving passing scores on commercial driving tests, the U.S. attorney’s office said.

The troopers are accused of falsifying records and giving preferential treatment to at least 17 drivers from May 2019 to January 2023, who were taking their commercial drivers license or CDL test. Even when the drivers failed a skills test, the troopers passed them and communicated they had done so with a text and the code word golden. Some troopers even joked in the text messages how badly a driver had performed on the test, according to the indictment.

“In short, as is alleged in this indictment, CDLs were for sale,” Acting United States Attorney Joshua S. Levy told reporters. “Troopers were bribed with free goods to pass applicants no matter how they performed on the test.”
