This small railroad crossing can do everything a big one can: It automatically switches to red, raises the movable barrier, or closes it with appropriate light and sound effects, thus teaching even the youngest children to follow the rules. Good to know for educators and parents: The railroad crossing can also be operated manually if they want to teach little ones to wait patiently until the crossing is clear again. This children's traffic education sign is inherently stable: The base, reminiscent of real mobile road signs, can even be weighted down to make it even more stable. Simply fill it with water, and the traffic light can withstand small bicycles, scooters, and tricycles.
