What percentage of ambulance occupants injured during a crash are typically not wearing seat belts?

The correct answer reflects a concerning trend regarding seat belt usage among ambulance occupants involved in crashes. Evidence shows that a significant majority of ambulance occupants, particularly patients, often do not wear seat belts during transport. This lack of restraint increases the risk of injury in the event of a collision.

Ambulance design and the nature of patient care can lead to circumstances where seat belts are not applied. For instance, patients in critical conditions may not be secured due to the urgent need for medical intervention, or because of the necessity to provide care during transit. This trend of not securing occupants can lead to a higher rate of injury during an accident, illustrating the importance of promoting and implementing safety measures to enhance occupant protection in ambulances.

In contrast, the other options present a more optimistic view of seat belt usage that does not align with the available data regarding ambulance occupants, thus emphasizing the need for better compliance with safety protocols.
