Final answer:
In driving regulations, there are specific limits on the front and rear extensions of loads on vehicles.
Step-by-step explanation:
In driving regulations, a load must not extend more than a certain distance for safety reasons. Specifically, a load must not extend more than 3 feet to the front of the vehicle or more than 4 feet beyond the poles or any protruding objects. However, in some cases, where it's necessary, the load can project 4 feet beyond the rearmost part of the trailer.
