Key Topics to Study
The ICBC Class 4 knowledge test isn't just about driving—it's about the safety and responsibility of carrying passengers. Here are the core areas you need to master:
1. Passenger Management & Safety
Understanding how to handle passengers is critical. This includes:
- How to safely load and unload passengers.
- Dealing with difficult or intoxicated passengers.
- The legal responsibilities of a commercial driver toward their passengers.
- Using safety equipment (fire extinguishers, first aid kits).
2. Pre-Trip Inspection Routine
Every commercial driver must perform a pre-trip inspection before every shift. You should know:
- The "Circle Check" method.
- How to check fluid levels, lights, tires, and brakes.
- Identifying "out of service" defects that make a vehicle unsafe to drive.
3. Commercial Road Rules
While you already know Class 5 rules, Class 4 adds specifics:
- Stopping at railway crossings (mandatory for some commercial vehicles).
- Understanding right-of-way in professional settings.
- Safe following distances for larger vehicles.
- Managing speed and space in heavy traffic.
4. Signs and Signals
Be sure to review commercial-specific signs, such as:
- Weight limits and height clearances.
- Truck and bus-specific lane markings.
- HOV lane rules for taxis and buses.
