What is the ICBC knowledge test in 2026?
The ICBC knowledge test is the written step every new British Columbia driver must pass before taking a road test (ICBC, 2025). BC uses a graduated licensing system (L → N → Full):
| Class | Min. age | What's tested | Conditions |
|---|---|---|---|
| L (Class 7L learner) | 16 | Knowledge test (40 q, 80%) | Display "L" sign; accompanied by Class 1–5 driver ≥ 25; no passengers (immediate family excluded); no alcohol; no electronic devices |
| N (Class 7N novice) | 17 (L held 12 months) | Class 7 road test | Display "N" sign; only one passenger (immediate family excluded) for first 6 months; no alcohol; restricted nighttime driving (later than midnight) for first 6 months |
| Full (Class 5) | 19 (N held 24 months) | Class 5 road test | Full driving privileges |
| Class 4 (commercial / bus) | 19 | Knowledge test (Class 4) + medical | Commercial passenger vehicles up to 25 passengers |
| Air Brake Z-endorsement | 19 + Class 1, 2, 3, or 4 | Air-brake knowledge test (50 q, 80%) | Required to operate air-brake-equipped vehicles |
The L test is the standard entry-point for new drivers; the Air Brake Z-endorsement is a separate add-on test for drivers who want to operate trucks, buses, or commercial vehicles with air brakes (ICBC, 2025).
