Response (active)	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. https://www.roadsidepooledfund.org/wp-content/uploads/2016/10/9-1002-12-7.pdf
