A B.C. Class 1 applicant asks whether they must take the separate single-unit air brake knowledge test. What is the best answer under ICBC guidance?

1. Yes, every Class 1 applicant must take the separate single-unit test after MELT
2. No; the Class 1 knowledge test includes air brake content and Class 1 MELT includes required air brake training
3. No, because Class 1 vehicles never use air brakes
4. Yes, but only after passing a motorcycle road test
