Folding reflective triangle warning signs Folding and portability: Folding reflective triangle warning signs can be folded together when not in use, making them convenient to carry. When in use, they can be opened and placed behind a car, serving as safety articles for driving out. Overview: When a car stops at the roadside in an emergency, this device is useful. Whether during the day, at night, or in bad weather, just place it a few meters behind the car. Because it is reflective, the light warning board is bright and eyecatching at night and can be seen from a distance. How to use and care: When stopping use, withdraw the left and right reflector plates and supporting feet in the reverse of the opening, and then put them into the packaging box. Pay attention to protect the red reflective surface and fluorescent surface when collecting signs, and avoid scratches. When connecting and disconnecting the left and right reflector plates, push or pull them along the direction of the groove to avoid damaging the sign plate. Placement guidance and orientation: The reflective surface of the open fault warning sign is placed in the direction of the vehicle behind the faulty vehicle. The vertical angle of the sign is 5' to the left of the vertical plane of the vehicle, and on common roads it is placed 30 to 100 meters behind the faulty vehicle. On highways it is placed 100 meters behind the faulty car. Use scenarios Scenario 1: Vehicle breakdown on a highway or road in day, night, or bad weather. Deploy the sign a few meters behind the car to warn following traffic and improve safety. Scenario 2: Parked stop on common roads. Place the sign 30 to 100 meters behind the faulty vehicle to provide advance warning to approaching drivers; on highways place it 100 meters behind the faulty vehicle. Scenario 3: After use, fold and store the signs in their packaging box, protecting the red reflective surface and fluorescent surface to avoid scratches and ensure readiness for next use.
