The X-LITE end terminal has saved lives and reduced the number and severity of injuries sustained from automobile accidents. Publicly available performance data that is reported monthly to the Federal Highway Administration (FHWA) demonstrates that the X-LITE performs as well as or better than similar products on the market and numerous states that use the X-LITE on their roads have confirmed that they’ve had no negative experiences.
In 2011, the FHWA issued a Safety Eligibility Letter reporting that the X-LITE passed all applicable standards and criteria. In 2017, the FHWA re-confirmed that finding in response to a request that the agency reexamine the X-LITE.
It is important to note that guardrail end terminals are designed to mitigate the risk of hitting fixed objects such as utility poles, steep embankments, concrete barriers, and other unyielding objects when a driver fails to stay on the road, but they cannot eliminate all the risks involved with an unintended exit. A variety of factors contribute to the potential for injury when this happens, such as speed, the angle at which a vehicle makes impact, and whether road safety equipment is installed and maintained properly.
