Ontario MTO Truck Knowledge Practice Test

The statement is correct. In Ontario, for safety and regulatory compliance, it is required that only individuals who have completed an approved air brake adjustment course or are certified mechanics are allowed to adjust air brakes on trucks. This ensures that the proper procedures and safety measures are followed, as air brakes are a critical component of a vehicle's safety system. Adjusting them incorrectly can lead to brake failure or decreased braking efficiency, posing a risk to the driver and other road users. The other options do not align with this regulation. For example, stating it’s false would imply that anyone could adjust air brakes without the necessary training or certification, which compromises safety standards. Therefore, the assertion that one must have specific qualifications to perform air brake adjustments is important for maintaining vehicle safety and operational integrity on the roads.
