Ontario MTO Truck Knowledge Practice Test

A truck should never be loaded beyond:

1. Half its weight capacity

2. Its licensed capacity

3. Twice its weight capacity

4. Weight capacity limit dictated by the driver

The correct answer is: Its licensed capacity

The correct answer is indeed determined by the truck's licensed capacity. This is the maximum weight that the truck is legally allowed to carry as specified by regulations and safety guidelines. Exceeding this limit can lead to a number of serious consequences, including a higher risk of accidents due to instability, increased wear and tear on the vehicle, and legal penalties for violating weight restrictions. The emphasis on licensed capacity is crucial because it is designed to ensure safe operation on public roads. Every vehicle has a specific design and build that dictates how much weight it can handle safely without compromising control and braking. Loading a truck beyond this capacity not only strains the vehicle but also poses danger to the driver and other road users. The other options, such as loading the truck to half of its weight capacity or relying on a subjective weight capacity limit dictated by the driver, lack the necessary legal backing and guidelines essential for safe operation. These alternatives could potentially lead to unsafe practices and misjudgment of the truck’s real limits.
