Do Front air bags are not designed to offer protection from crashes from the rear and side?

Correct, front airbags are specifically designed to protect occupants during frontal collisions by deploying from the steering wheel and dashboard. They do not provide protection in rear or side impacts, as their primary function is to reduce injury risk in head-on crashes. For side impacts, vehicles may have side airbags that deploy from the door or seat area, and rear collisions generally rely on other safety features such as seat design and seatbelts.
