When a car and a truck collide, the car is at a serious disadvantage. One particularly devastating type of crash is when the car slides underneath the back of a heavy tractor-trailer. The federal government requires that most heavy truck trailers be equipped with underride guards, which are steel bars that hang down from the backs of trailers. These are designed to prevent the front of passenger vehicles from moving underneath in a crash to the back. Most do a good job, thus increasing survival chances during a crash, as shown by a recent test by the Insurance Institute for Highway Safety (IIHS). However, in crashes involving only a small portion of the truck’s rear, most trailers fail to prevent potentially deadly underride accidents from occurring.

Crash Test Results

The Institute tested trailers to see how well guards prevented underride in a 35 mph crash. Trailers were tested from eight different manufacturers, which together account for 80% of the heavy truck trailer market. Each trailer, which met U.S. and Canadian standards, was tested up to three times; in a full overlap crash test, a 50% overlap crash test and a narrow overlap crash test.

All trailers prevented underride in the full overlap crash test at 35 mph. All but one prevented underride in the 50% overlap scenario. And, only one, manufactured by Manac, prevented underride in all three-overlap tests.

Underride Guard Requirements are Inadequate

Modern cars are equipped with a crush zone at the front that is designed to minimize injury to occupants, but this crush zone only works in a collision with a trailer if the trailer’s underride guard stays in place.

Research shows that minimum strength and dimension requirements for underride guards are inadequate, prompting the Institute to petition the National Highway Traffic Safety Administration (NHTSA) for more stringent requirements. Already, though, trailer manufacturers have responded by installing guards that are significantly stronger that the agency mandates.

A likely reason for this is that trailers in Canada have had to meet tougher guard standards since 2007.

Underride Guard Improvements

In their successful underride guard, Manac engineers have moved the vertical supports further from the center of the trailer, which makes the ends of the guard stronger. With this guard, not only did the test car and dummy fare better, but the trailer sustained less damage and was less expensive to repair. The IIHS test indicates that the tougher Canadian requirements are a good first step, but that design improvements are necessary to make underride guards even more effective.

Crash Image From IIHS TestingIf you are considering a minicar as your next automobile purchase, you may want to think again. While smaller cars are becoming popular, they do not stand up to overall crash testing nearly as well as larger vehicles. The Insurance Institute for Highway Safety’s small overlap front crash test found that only 1 minicar out of 11 that were tested achieved an acceptable rating. The rest—FAILED.

Among those tested, only the Chevrolet Spark received an acceptable rating and good ratings in the Institute’s four other crashworthiness evaluations. This was enough to earn the Spark the 2014 Top Safety Pick award. No other minicar passed the test.

According to the Insurance Institute for Highway Safety, “The small overlap front crash test replicates that happens when the front corner of a vehicle collides with another vehicle or object, such as a tree or utility pole”. When they perform the test, 25% of the minicar’s front end on the driver’s side must strike a rigid barrier—at 40 mph. This effectively bypasses the front-end crush zone and makes this test more difficult than other head-on crash tests.

While car manufacturers have found a way to improve vehicle structures on larger automobiles to achieve safety in these tests, minicars are at a disadvantage. Small cars are also at a disadvantage, but as a group, they performed better than minicars. 10 out of 17 small cars tested were able to achieve at least acceptable ratings.

When an automobile doesn’t perform well on the overlap front crash test, it means that vehicle structure is compromised. This can knock airbags out of place and collapse the driver compartment drastically causing serious and fatal injuries.

Of all the minicars evaluated, the Honda Fit and the Fiat 500 fared the worst with serious issues. The Fiat 500 even had its driver door torn off at the hinges. The crash test dummy also hit his head on the instrument panel because the airbag was compromised. He also sustained serious leg injuries as the steering components were pushed back into the dummy model.
