Why are undeployed airbags considered a safety hazard?

Undeployed airbags are considered a safety hazard primarily because they may deploy if the sensors are further disturbed. In a vehicle that has been involved in a crash, undeployed airbags are in a state where they could potentially deploy during further movement or jostling of the vehicle, particularly during a thorough investigation or when other interventions like towing are taking place. This unpredictability poses a significant risk to those working in or around the vehicle, as the airbags are designed to deploy with considerable force in a collision, which can cause injury.

The other options, while they may present concerns in certain contexts, do not encompass the primary reason for classifying undeployed airbags as hazardous. The potential for unintended deployment makes it crucial for investigators and technicians to handle vehicles with undeployed airbags cautiously and with appropriate safety measures.
