The 2026 ICBC (Insurance Corporation of British Columbia) knowledge test has 40 multiple-choice questions and a pass mark of 32/40 (80%) (ICBC, 2025). The Class 7L (learner) knowledge test is the standard entry-point for new BC drivers; the Class 4 (commercial) and Air Brake Z-endorsement tests add 30 and 50 questions respectively. This free ICBC knowledge practice test covers 25 sample questions covering road signs, rules, and Air Brake Z-endorsement content, plus the 2026 booking fees and ICBC-aligned explanations.

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. 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.

8-week prep plan
A proven cadence that scales to any starting level — adjust hours, not the sequence:
- Weeks 1–2 — Diagnostic + base content. Take a full-length timed diagnostic. Score it. Identify the bottom-three sections. Spend 6–8 hours/week on foundational topics (formulas/grammar/reading pacing). Free official practice tests are the best starting material.
- Weeks 3–4 — Skill building. Switch to a structured book or course. Daily practice questions with active review (re-visit every missed question the next day). Add a weekly timed section. Hours: 8–10/week.
- Weeks 5–6 — Full practice tests. One full timed test per weekend + a 60-minute review session analyzing every wrong answer. Mid-week: timed sections only on the weak sections. Hours: 10–12/week.
- Weeks 7–8 — Sim + taper. Two full timed tests per week under strict test-day conditions (same start time, same breaks, same allowed items). Light review the final 48 hours. Hours: drop to 6 hours the final week.
Free resources: Official test-body practice tests (highest fidelity). Khan Academy (for SAT digital). Test-maker mobile apps for on-the-go drills.
Paid resources: Use a single recent-edition prep book from a major publisher. Avoid courses older than 2 years; test format changes.
What to do next
- Bookmark the official test-body calendar page; dates + registration windows post 12+ months out.
- Pull together your testing-day ID and approved calculator (if applicable) the week before.
- Reach for the prep book that matches your weakest section; don't try to read every book.
- Book your seat at the first sitting that fits — early dates give you a retake cushion if needed.
