A driver is preparing for Illinois Passenger endorsement skills testing in a bus equipped with air brakes and a wheelchair lift. Which preparation is most complete?

1. Study Sections 2 and 4 only, because passenger buses never require air brake checks
2. Bring a representative passenger vehicle and be ready to inspect passenger entry, lift, emergency exits, seats, brakes, lights, mirrors, tires, and other equipped safety items
3. Bring any car because only the written test matters
4. Skip pre-trip preparation if the bus has a current registration
