I'm off to the Dodge dealer today for some warranty work. They're replacing the passenger side airbag as part of the Takata recall. They replaced the driver side bag about a year ago, and are just now replacing the one on the other side.
On the truck we owned before this one, the passenger side bag could be disabled by a switch operated with the ignition key, but this truck does not have that option.
For years before that, the driver acted as a safety device, throwing his arm across anyone in the passenger seat in an emergency. I don't know if it worked, but it was probably as effective as a Takata air bag.
