This a futuristic model of a construction barrier. It has a screen in the front where any words can be lit up and seen at night time just like during the day. Its portable, but once placed down, it will lock on to the ground with such a strong magnetic strength that it can stop an oncoming truck. The blinking red light shows that the barrier is active. Plus on the front of the screen, behind it are solar panels that recharge the sign, making it run 24/7.
