Final answer:
The bumper height requirements for trucks that weigh between 2000 and 3000 pounds are 18-22 inches (option 2) to ensure safety in the event of a collision.
Step-by-step explanation:
The bumper height requirements for trucks that weigh between 2000 and 3000 pounds are 18-22 inches (option 2). These requirements are determined to ensure the safety of both the occupants of the vehicle and pedestrians in the event of a collision.
By having a minimum bumper height, it helps to mitigate the impact force on the passenger compartment during a crash. Additionally, the height requirements also ensure that the bumpers line up correctly with other vehicles, providing effective crash protection.
