Theres no argument that seatbelts DO save lives. My car, or whatever motor vechicle I am riding in (firetruck, ambulance or a car) I always have my seatbelt on before that vechicle is in "D". I have (as im sure a lot of you have) seen countless RMA's and many minor injuries from MVA's from people wearing their seatbelts, and just say they didnt chose to, im sure a lot of them would have been airlifted.
I do think that is should be a Department policy to wear seatbelts when responding to calls/going back to quarters, however if someone doesnt I dont think they should be give a fine for it. Especially a volunteer fireman. These peoploe risk their lives for no other reason other than they want to help, and I think its nothing short of bullshit that this guy or any guy gets imprisoned for not wearing a seatbelt.
