Simply put, guardrails are supposed to protect cars, drivers, and passengers. At the very least, they can prevent a bad situation, such as a car or truck wreck, from turning even worse. On highways and interstates, they can prevent cars from running off the road, falling down an embankment, or veering into oncoming traffic. When not functioning properly, bad things can happen. Drivers in many states have been having serious problems with guardrails recently, and at least seven people have died as a result of deadly guardrails in Tennessee, Virginia, and Missouri.
One such incident occurred near Knoxville, Tennessee, when a 17-year-old girl was killed in a car accident caused by a defective guardrail. The driver veered off the road, drove into the median, and hit the end of a guardrail. While the guardrail was supposed to help absorb the impact with the vehicle, the end actually pierced through the vehicle, hitting the driver in the head.
The type of guardrail in question is X-LITE, which is manufactured by Lindsay Transportation Solutions. There are currently 1,700 of them on Tennessee roads, interstates, and highways. TDOT conducted its own investigation into this type of guardrail and found that they did not always work when cars hit them traveling at speeds 62 mph or higher. Usually, 62 mph is the standard crash test speed for guardrail ends. TDOT also found issues with the installation instructions, which, according to TDOT, “could result in the terminal performing differently from the original tested conditions.” Right now, Tennessee is accepting bids to replace all of these guardrails. Once complete, the final cost could end up being $3.5 million or more.
