Due to their size and weight, commercial motor vehicles:

Commercial motor vehicles, due to their larger size and weight compared to passenger vehicles, take longer to stop when they are in motion. This is primarily because of the increased momentum and inertia that comes into play with larger vehicles. The greater mass requires a longer distance to come to a complete stop, especially when considering factors such as road conditions and the vehicle’s load. Drivers must account for this extended stopping distance to maintain safety on the road, which is especially critical when merging, navigating traffic, or responding to sudden stops.

In contrast, the other options do not accurately reflect the nature of commercial motor vehicles. For instance, they are generally not faster than passenger vehicles, typically have lower fuel efficiency due to their size and load, and they tend to have more challenges maneuvering in tight spaces rather than being more agile than smaller cars. Understanding these dynamics is crucial for safe operation and management of commercial motor vehicles.
