Ontario MTO Truck Knowledge Test 2025 – 400 Free Practice Questions to Pass the Exam

During a road test, it is imperative to ensure that the vehicle's windshield wipers are in proper working condition. The windshield wipers play a crucial role in maintaining visibility, especially in adverse weather conditions such as rain or snow. If the wipers are ineffective or malfunctioning, it can lead to poor visibility, increasing the risk of accidents. Therefore, the ability to clear the windshield is a fundamental safety requirement that drivers must be able to rely on.

While parts like air conditioning and the vehicle's suspension are important for comfort and general vehicle performance, they do not directly impact immediate safety as significantly as the windshield wipers. The functionality of the radio, while it might contribute to a more pleasant driving experience, is not relevant to safety and vehicle operation during a road test. The focus is primarily on essential components that affect the driver's ability to operate the vehicle safely on the road.
