Why do some newer commercial trucks use automated manual transmissions, and what does this mean for the CDL knowledge test?

Pick an answer

1. They require a completely separate CDL class
2. They only appear on the knowledge test if the vehicle used for testing has one, a common blind spot when it comes to test
3. They shift gears for the driver, but a driver may still need a manual restriction removed by testing in a manual vehicle
4. They are only used in Class B vehicles, never Class A
