Foto de stock - 23 November 2018, Lower Saxony, Garbsen: Ulf-Birger Franz, Head of the Department of Economics, Transport and Education in the Hannover Region, presents the new ""Bike-Flash"" warning system in an industrial park at an intersection. The system uses heat sensors to monitor the blind spot of vehicles up to a distance of 40 meters. If a cyclist or pedestrian is detected by the system, four lights flash at different heights and warn the truck driver. Cyclists are also warned if they are in the blind spot.
