What does the two red triangle signs mean?

[DiMargaret]

Two red triangle signs indicate the hazard warning flashers. When a motor vehicle breaks down on the road and cannot move forward, the driver needs to exit the vehicle to inspect the issue. Immediately activate the hazard warning flashers and move the vehicle to a location where it does not obstruct traffic for inspection. If a vehicle breaks down on the highway, it should be parked in the emergency stopping lane. Promptly turn on the hazard warning flashers, place a hazard warning sign at least 150 meters behind the disabled vehicle, and quickly call for emergency assistance. The driver and passengers should wait for rescue outside the front guardrail of the disabled vehicle. In the event of a sudden vehicle breakdown while driving on the road and being unable to move to a safe area promptly, immediately activate the hazard warning flashers to alert passing vehicles and pedestrians for safety, call for emergency assistance, and wait for rescue.
