Mikhail Yevdokimov, the governor of Altai region, was killed in August 2005 when his car crashed into a tree after a collision with a car driven by Oleg Shcherbinsky.
Yevdokimov's driver and bodyguard were killed in the crash, and his wife was seriously injured.
A local court convicted Shcherbinsky of traffic violations resulting in the death of two or more people. He was sentenced to four years in a minimum-security correctional labor settlement.
Shcherbinsky has denied any blame in Yevdokimov's death, saying the governor's car was traveling so fast he could not avoid the collision.
His lawyer said he will appeal the sentence.
