Final answer:
Large trucks take longer to stop than passenger vehicles because of their greater mass and cargo, as well as the mechanics of their braking systems. Not all trucks have air brakes, and even with air brakes, they don't necessarily stop quickly. Trucks are also less maneuverable than passenger vehicles. The correct option is a-They take longer to stop than passenger vehicles
Step-by-step explanation:
Among the statements provided regarding large trucks, the true statement is that they take longer to stop than passenger vehicles. This is due to a combination of their greater mass and often larger cargo load, which increases their momentum.
When considering stopping distances, we not only have to consider the distance a driver covers before hitting the brakes, known as the perception-reaction time, but also the time and distance it takes for the truck to stop upon brake application, which depends on factors like brake system, weight, and road conditions.
It is a misconception that all large trucks have air brakes that allow them to stop quickly. While air brakes are common in heavy trucks, they do not necessarily allow for quicker stops compared to hydraulic brakes.
Also, large trucks are generally less maneuverable than passenger vehicles due to their size and weight. The correct option is a-They take longer to stop than passenger vehicles
