Class B to Class A Upgrade for Tennessee CDL Applicants
Tennessee's central position and automotive industry make it one of the most active CDL freight corridors in the South. With automotive manufacturing, healthcare and medical distribution, music and entertainment logistics driving much of the freight in Tennessee, the Class B to Class A Upgrade material below is the part of the Tennessee CDL that those employers screen for first.
The Tennessee Class B to A upgrade: Combination Vehicles and Air Brakes knowledge tests at Tennessee Driver Services, then a Class A skills test. Since February 2022, ELDT theory and behind-the-wheel training must also be logged with an FMCSA-registered provider before Tennessee Driver Services will schedule the test.
Where Tennessee drivers use this
