Final answer:
The correct answer is option 3) five feet. The correct answer is that a load may not extend over the rear of a truck more than five feet, as this is a commonly accepted legal limit to ensure road safety.
Step-by-step explanation:
When transporting a load on a truck, it is important to follow legal regulations regarding how far a load can extend over the rear of the vehicle to ensure safety on the roads. In many places, the legal limit for how far a load can extend beyond the back of a truck is no more than five feet. It is crucial for truck drivers and hauling companies to adhere to these regulations to prevent accidents and to avoid penalties. An overextended load can pose significant risks to other drivers, as it can obstruct visibility or interact with other vehicles in dangerous ways.
According to vehicle safety regulations and guidelines, the load on a truck should not extend over the rear of the vehicle more than four feet. This restriction ensures that the load does not pose a hazard to other vehicles or pedestrians, and maintains proper balance and stability for the truck. Exceeding this limit can result in accidents, damage to the truck, or violation of traffic laws.
