This crash occurred in circumstances that met all these conditions: the road is a divided highway, straight and flat. The surrounding landscape is almost featureless, and there are no overhead light gantries or signs. The crash occurred two minutes before the start of civil twilight, but the weather was dry and clear - in other words, almost the perfect conditions for spotting a truck right in front, so there are problems with its performance even in its natural environment.
