Concrete Barrier Sloped End Section

Question
State UT
Description Text

What are your thoughts on this design passing a TL-2 test?  My thoughts are, the vehicle will most likely rollover and crush the passenger compartment resulting in a failure.

Crash testing under an old NCHRP study revealed that these sloped end treatments up to full PCB height will result in vehicle instabilities and rollover at speeds similar to TL-2.

The only MASH TL-2 evaluation of a similar end treatment was a shorter option for a TL-2 PCB.
