Alabama State Troopers identified the fatality victim as Kimberly D. Mahaffey. She was 50 and lived in Warrior. . .

Mahaffey was driving a Toyota Rav 4 when she struck a Kenworth tractor-trailer driven by a Tennessee man. 1 killed in crash with tractor-trailer on I-65 in north Jefferson County

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 —front, side, and rear — leaving passenger vehicle occupants vulnerable to life-threatening injuries.

Kimberly Mahaffey, Precious One Gone Too Soon

Note: In order to raise awareness and preserve the memories of underride victims — precious ones gone too soon — I have been writing memorial posts on what could potentially be underride crashes. I am not a crash reconstructionist, and I do not have all the facts on these crashes; but underride should be investigated as a potential factor in truck crash injuries and deaths.

We are asking that people send us crash reports for collisions with trucks which they suspect involved underride. Send them to marianne@annaleahmary.com. We will submit these as complaints to USDOT. Read more here: Launching a Campaign To Flood NHTSA With Underride Complaint Reports.
