What is a requirement for emergency responders working in highway operations as of 2009?

Emergency responders working in highway operations are required to wear ANSI safety vests, as this meets the established safety standards for visibility. The American National Standards Institute (ANSI) specifies requirements for high-visibility apparel to ensure that responders can be seen by motorists, especially in low-light conditions or during adverse weather. This requirement is vital for protecting responders from accidents, as they often work close to moving vehicles in potentially dangerous situations.

The focus on ANSI safety vests emphasizes the importance of visibility in enhancing safety on highways, where traffic poses a constant risk. It ensures that responders are equipped with gear that stands out against varying backgrounds, thus reducing the likelihood of vehicle-related accidents while they perform their duties.
