Take a look at this Pierce website entitled "Certified Crash Testing." They show a Quantum cab undergoing a frontal crash test. The only problem is, the cab fails! In order to pass, all crew compartment doors have to remain closed and latched after the impact. At about the 4 second mark in the video, you can plainly see that the officer's door pops open. Why would Pierce place a video on their website that shows a truck failing a crash test?
