Suspended warning triangle

There are provisions in the traffic laws of various countries. In case of vehicle failure, a triangle warning frame must be placed at the rear of the vehicle to remind the vehicles coming from behind to pay attention to the bad vehicles ahead and need to reduce or detour. And how many traffic accidents were caused by serious traffic accidents because the warning triangle was not noticed. The correct way to use the traditional triangle warning frame is to place it 50-100 meters behind the vehicle. But on a highway with a speed of more than 100 per hour, if you are not careful, there will be danger. ATWS is designed to make it easier for drivers to detect broken cars in front of them. Equipped with balloon device, so that drivers can know the road ahead earlier, coupled with Bluetooth device, can be the first time to inform the network world.
