An applicant wants a Passenger endorsement for a specific CDL vehicle group but arrives for the skills test in a non-passenger cargo vehicle. What is the problem?

1. Federal rules require the skills test to be taken in a passenger vehicle satisfying that vehicle group's requirements
2. A cargo vehicle is always acceptable if it has enough empty seats
3. The applicant can substitute a higher knowledge-test score for the passenger skills test
4. The vehicle type matters only for the air brake test
