Ontario MTO Truck Knowledge Practice Test

Commercial motor vehicles are restricted in width to a limit of:

1. 2.2 metres

2. 2.4 metres

3. 2.6 metres

4. 2.8 metres

The correct answer is: 2.6 metres

The correct width limit for commercial motor vehicles in Ontario is 2.6 meters. This regulation ensures that vehicles can safely navigate roadways without encroaching on adjacent lanes or paths. Adhering to the dimension standards helps promote road safety and prevents potential accidents caused by oversized vehicles struggling to maneuver effectively. The limits set in the regulations are based on standard roadway dimensions and the need to maintain safe distances between vehicles. This is particularly important in terms of passing, turning, and the overall flow of traffic. The specific width of 2.6 meters has been established to accommodate a wide range of vehicles while minimizing risks to other road users. Other width limits, such as 2.2 meters, 2.4 meters, and 2.8 meters, do not align with the regulations set out for commercial motor vehicles in Ontario, indicating that they fall outside the defined maximum allowable dimensions. These limits help ensure that commercial vehicles can operate safely and efficiently within the constraints of the roadway infrastructure.
