safe sign / warning sign

safe sign

When my car broke down on the highway,it was dangerous to leave the car to put the warning sign about 20m behind the car. The safe warning sign makes people operate it near the car safely. You can push the warning sign which has four wheels to the place you want to put. And you can rotate the handle to get back the warning sign through the belt.
