the air bag system is triggered off acceleration/deceleration sensors. it takes a pretty good impact to trigger the system though. it looks like alot of damage but it probably didnt jarr the truck too much beacuse that pole is a pretty small diameter. basically the air bag system has a see a specific amount is g-force to trigger. its hard to tell by the photos but the bags may have deployed, or atlest the drivers did and the pass may have been turned off too.
