Ontario Bus Driver Knowledge Test 2025 – 400 Free Practice Questions to Pass the Exam

Before starting their shift, a bus driver must ensure that the brakes, lights, and fluid levels are in proper working order. This is crucial for the safety of both the driver and the passengers. Checking the brakes is essential to ensure that the bus can stop effectively, preventing accidents. Confirming that the lights are functional is important for visibility and communication with other vehicles, especially in low-light conditions. Monitoring fluid levels, such as oil, coolant, and windshield washer fluid, ensures that the bus operates efficiently and can handle various driving conditions without mechanical failure.

The other choices address aspects that are not critical for immediate safety or operational readiness. While comfort of the seats and passenger feedback may contribute to a positive riding experience, they do not impact the essential safety checks required before driving. The entertainment system is also not a priority in ensuring the bus is safe and ready to operate. Thus, checking the brakes, lights, and fluid levels is the most vital task a bus driver must complete before beginning their shift.
