Total side removal involves removing which parts of the vehicle?

Total side removal refers to a specific technique used in vehicle extrication during rescue operations, aiming to create a clear passage for accessing trapped individuals. The correct option highlights the removal of the front door, back door, and B post, which are essential components for effectively accessing the interior of the vehicle.

By removing both doors and the B post, emergency responders can create a wider opening that allows them to reach occupants safely and efficiently, especially in situations where they might be pinned inside. This technique can significantly improve the speed and effectiveness of rescue efforts, ensuring that those injured are removed from the vehicle quickly and without additional harm.

Additionally, the other options present elements of the vehicle that might be involved in different types of extrications or vehicle modifications, but they do not serve the same purpose as total side removal. Removing the windshield and hood or the roof and rear window does not provide the necessary access to the interior, while front bumpers and truck beds may not be relevant in a typical rescue scenario focused on extracting individuals from the passenger compartment.
