Why do commercial trucks not have SRS Airbags?

Commercial trucks typically do not have SRS (Supplemental Restraint System) airbags primarily due to their design and intended use. These vehicles often have a different safety structure, relying on robust construction and larger crumple zones to absorb impact forces. Additionally, the risk of injury from airbags deploying in a larger vehicle can outweigh their benefits, as commercial trucks are generally driven in a professional context where seatbelt use and driver training are emphasized. Moreover, regulations and standards for commercial vehicles differ from those for passenger cars, leading to variations in safety features.
