Warning tripods play a particularly important role in traffic, while traditional tripods have many
shortcomings and cannot convey information to the rear vehicles in a timely and better manner.
This tripod uses compressed gas to inflate the balloon into the air, and project the warning area
at high places. Use new methods to remind vehicles behind you to take detours faster and more
conspicuously. It is usually placed in the car, and can be attached to the roof when in use.
