When should high visibility vests be worn at roadway crash scenes?

High visibility vests should be worn at all times during roadway crash scenes to enhance the safety of personnel and bystanders. These vests are designed to improve visibility to approaching traffic, regardless of the time of day or traffic conditions. Wearing high visibility clothing is a precautionary measure that significantly reduces the risk of accidents involving emergency responders.

The need for consistent visibility becomes critical in low light conditions or poor weather, situations where visibility may be compromised. Additionally, wearing these vests during times of calm traffic can help ensure that responders are always protected, as conditions can change rapidly. This practice aligns with safety protocols designed to minimize the risk of injury while working in environments shared with moving vehicles.
