When big vehicles make slow turns, sometimes the process can be dangerous.
The diagram shows the area between the dotted and solid curved lines which is swept out by an articulated lorry.
Today’s invention is to equip these vehicles with a number of roof-mounted spotlights which shine eg red light onto the ground. These are directed, by data on of the current steering wheel position, to illuminate the road area which is about to be swept through.
If people or other vehicles find themselves located in this brightly coloured light, it’s time to pull back to safety.
This system might also be useful to learner drivers, for whom every vehicle feels like a behemoth.
