Former MSP trooper sentenced for falsifying records for CDL tests

BOSTON, Mass. (WLNE) — A former Massachusetts State Police trooper was sentenced for his role in a scheme to falsify Commercial Driver’s License test scores and pass applicants that either failed the test or did not complete the full test, according to the U.S. Attorney’s Office for the District of Massachusetts.

64-year-old Calvin Butner, of Halifax, was sentenced to three months in prison, followed by one year of supervised release with the first three months of home confinement.

According to the USAO, Butner was a member of MSP’s CDL unit, which administered CDL tests that allow for a person to drive a commercial vehicle.

The USAO said between May 2019 and January 2023, Butner and three other CDL members “conspired to give preferential treatment to at least 17 CDL applicants” by giving passing scores on their tests regardless if they failed or passed.

Butner passed three applicants who failed the test and five applicants who did not take the test, according to the USAO.

Butner pled guilty in April 2025 to one count of conspiracy to falsify records, three counts of falsifying records and aiding and abetting and five counts of making false statements.

All recipients who fraudulently passed their CDL test and were identified have been reported to the Massachusetts Registry of Motor Vehicles.
