This partnership has been very useful to us over the years.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"680\" src=\"https:\/\/newsroom.carleton.ca\/wp-content\/uploads\/crash-test-aftermath-1200x680.jpg\" alt=\"\" class=\"wp-image-55155\" srcset=\"https:\/\/carleton.ca\/news\/wp-content\/uploads\/sites\/162\/crash-test-aftermath-1200x680.jpg 1200w, https:\/\/carleton.ca\/news\/wp-content\/uploads\/sites\/162\/crash-test-aftermath-1200x680-300x170.jpg 300w, https:\/\/carleton.ca\/news\/wp-content\/uploads\/sites\/162\/crash-test-aftermath-1200x680-400x227.jpg 400w, https:\/\/carleton.ca\/news\/wp-content\/uploads\/sites\/162\/crash-test-aftermath-1200x680-768x435.jpg 768w, https:\/\/carleton.ca\/news\/wp-content\/uploads\/sites\/162\/crash-test-aftermath-1200x680-700x397.jpg 700w, https:\/\/carleton.ca\/news\/wp-content\/uploads\/sites\/162\/crash-test-aftermath-1200x680-200x113.jpg 200w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p>The 170-cm, 76-kg dummy named James was hit twice by a pickup truck driven by a member of the OPS.
