‘Routine control’, is a self-propelled replica of the German standard construction site beacon type “K1”. According to official estimates, there are currently as many K1s on German roads as there are German citizens driving on streets and motorways. As all citizens are well trained to follow the simple instructions of the K1, it can be assumed that a self-propelled version of this highly popular warning beacon will lead the country into a bright future. Caution, danger from oncoming traffic.
