At which impact speed must you reckon with serious or deadly injuries when no safety belt is worn?

In the context of traffic safety and injury risk in a vehicle, without a safety belt, the likelihood of serious or fatal injuries increases significantly with speed. According to German traffic regulations, serious injuries can occur from impact speeds as low as 30 km/h, and the risk escalates at higher speeds, particularly from 50 km/h and onwards.

This cumulative perspective emphasizes that even at lower speeds like 30 km/h, if a safety belt is not worn, the consequences of a collision can still be devastating. Therefore, it's crucial to recognize that both speeds of 30 km/h and 50 km/h are associated with serious injury risks when not wearing a seatbelt. The correct approach often involves acknowledging multiple thresholds for risk, which is important for understanding the full scope of safety measures in vehicle operation.

Always wearing a safety belt is a fundamental precaution that significantly lowers the risk of injury or fatality in the event of an accident, regardless of the speed.
