The speed at which airbags deploy can vary depending on the specific vehicle and the design of its airbag system. Generally, airbags are designed to deploy when a significant deceleration or impact is detected, rather than being based solely on a specific speed threshold.
Airbag deployment is triggered by sensors that monitor various factors, such as the rate of deceleration, the angle of impact, and sometimes the location of impact on the vehicle. When the sensors detect a collision or impact that meets the predetermined criteria, the airbags are deployed.
While there is no fixed speed at which airbags deploy universally, they are typically designed to deploy in severe accidents where the vehicle's speed is relatively high. This can include situations such as head-on collisions, high-speed side impacts, or rollover accidents.
It's important to note that the deployment of airbags is a complex safety system that involves multiple factors, and it is always best to consult the specific vehicle's manufacturer and refer to the owner's manual for detailed information on airbag deployment in a particular make and model of vehicle.
