The document also provides examples of acceptable models from different manufacturers, indicating that there are multiple options available in the market. However, it emphasizes that any equipment delivered must meet all the detailed specification requirements. Furthermore, it states that units from manufacturers with documented performance issues may be disqualified, highlighting the importance of reliable and high-quality equipment.
Additionally, the document mentions that all units must meet the crash worthiness requirements set by the National Cooperative Highway Research Program (NCHRP) 350. This requirement ensures that the arrow board sign is designed and constructed to withstand impacts and protect both the equipment and the individuals in the vicinity in the event of a crash.
Overall, the document provides detailed specifications and requirements for a solar and battery-powered trailer-mounted arrow board sign, ensuring that the equipment meets safety standards, utilizes the latest LED technology, and complies with crash worthiness regulations.
