What speed do airbags deploy on a Chevy Yukon?

Answer 1

virtually any speed. airbags are not deployed based on speed (this is a common misconception). They are based on the vehicles detection of a sudden stop or reduction of inertia. Example: going 30 mph and hitting a brick wall. Thus, stopping your vehicle instantly.

Example 2 : Going 70mph and hitting the back of a car that is going only 30 mph. This is a reduction of inertia based on the fact that your vehicle didnt stop but did have enough of a reduction in inertial forces to cause the deployment of an air bag.

vehicles equipped with airbags have multiple sensors and modules to detect whether an accident warrants the deployment of airbags. They analyze and interpret this info as the event is occurring. it is a very fast and reliable system.
