What MPH for the airbags to go off?
Rear ended someone who decided to drive 10 mph on the freeway while driving by a parked car that was all the way on the shoulder. It was on a merging/exiting lane and I had no where to go. Anyway everyone is safe but my airbags didn't blow. I was probably still going 30-40 mph at the time after slowing down as much as I could. A little unsettling especially when the estimator pointed out little round marks on the bumper where the sensors almost poked through.

@BayX5 , Glad you are ok.
Not sure how fast that you need to be before impact, but it seems like the impact doesn't produce enough to trigger the airbag.

I'd rather not have an airbag blow in my face to be honest but it's a little unsettling to hear that it probably should have from several people. It's my wife and kids daily. |

Glad everyone is ok. Surprised they didn't blow. Probably a case by case basis and that both cars were moving same direction. Who knows. These cars have more computing power than the apollo moon missions.

Special field tech is going to check it out. Was just hoping to get a mph impact rating to expect it at. I'm sure they'll have an explanation for it... just need it to make sense. It was a good hit. Radiator busted and everything.

"Everyone is safe" That tells you everything you need to know. Airbags are meant to prevent serious injury and death. They do that by imparting injury to your face and/or arms and hands (if they happen to be in the way) that is hopefully less serious than the injury that would otherwise happen. If there were no serious injuries, you should be glad that the airbags did not deploy. It's not a pleasant experience. The research that has gone into airbag deployment has advanced considerably over the years. It has less to do with any perceived damage or your speed, and more to do with accelerometers. Apparently, the impact was not hard enough to cause serious injury, therefore it wasn't hard enough to deploy the bags, rightly so. Consider yourself lucky the impact wasn't harder. Consider yourself lucky the bags didn't deploy. Consider yourself lucky nobody was hurt.

I often see cars with significant front end damage where the airbags haven't deployed because the cars front end dives with hard breaking so the solenoids aren't contacted.

I hit a deer at 85 mph, my airbags didn't deploy either.
I don't think deployment has any relevance to speed.

Hitting a deer at 85 might not set them off, but hitting something solid like a cement bridge abutment at 30 might. Hitting another vehicle would be somewhere in between, depending on the speed differential between the two vehicles and how large the other vehicle is. Hit a body on frame pickup square on the rear bumper and it probably would have deployed. Hit a small car and it's a totally different impact. It's all determined by deceleration forces. Lots of variables, but the main ones would be how much mass (how big is it) and how solid is the point of impact, and the angle of impact. All the things that determine actual deceleration forces.

It may feel like you were going 30-40mph at the time of impact but I imagine the damage would be far worse. Your front end looks like the front of my M3 after I was rear ended by a truck and got pushed into the car ahead of me. I was at a standstill and maybe hit the car ahead of me at 10mph
I think I read somewhere that the airbags are disabled at speeds below 15 or 20 mph |
