On a roadway, under which condition should a DOT-approved vest not be worn?

• A. Once an accident has been cleared
• B. If the incident has been moved more than 25 ft from travel lanes
• C. While actively fighting a vehicle fire
• D. If barriers have been erected that halt the flow of traffic

Answer: (C)

High-visibility vests help you be seen in traffic, but protection in a fire zone comes from gear designed for heat and flame. While actively fighting a vehicle fire, you need flame-resistant turnout gear and other PPE that shields you from radiant heat and flames. A DOT-approved vest offers limited protection and can interfere with your protective ensemble or mobility, so it should not be worn during active firefighting. Once you’re out of the hot zone or out of the firefighting phase, the vest can be used again to maintain visibility in traffic.
