What will it take to get UNDERRIDE on DOT Regulatory Agenda?

After numerous petitions, comprehensive underride rulemaking still has not made it the onto the DOT Unified Regulatory Agenda.

A public commitment to Vision ZERO is lip service when it does not result in substantive action. What would constitute tangible progress?

1977 IIHS Appeal for Federal Action on Underride
1989 IIHS Status Report on Front Underride Protection

According to Fisher, Kayla Marie Troutman, 32, of Lexington, was traveling east when her vehicle crossed the center line and collided head-on with a tractor trailer. She was wearing a seat belt when the collision occurred. Troutman was pronounced dead on-scene due to her injuries. Lexington woman killed in head-on tractor trailer collision, coroner identifies

Because the bottom of a truck is higher than the bumper of passenger vehicles, when there is a collision the smaller vehicle easily slides under the truck and the first point of impact is the windshield. Seatbelts, airbags, and car crumple zones do not function as intended in underride crashes —frontside, and rear — leaving passenger vehicle occupants vulnerable to life-threatening injuries.
