  1. In the front seat next to the driver ✔
  2. Anywhere in the vehicle
  3. In a car following behind

Why: The CDL holder must have the right class and endorsements and sit in the front seat beside the trainee, watching and supervising. On a bus they sit directly behind the driver or in the first row.

Huh, didn't know that: The supervisor must be allowed to drive that same vehicle on that trip.
