Driving in the night time course is mandatory for getting a primary driving license.
Driving in the night time is especially dangerous for safety, due to road reference points that drivers use in the day time are less or not visible in the dark. There is a danger of mixing right and oncoming drive lanes for example. Due to low traffic intensity drivers might think that night roads are good for driving fast, but this is far from being true.
Low visibility, tired drivers, wild animals on road, worse concentration and ability to assess speed and distance in the night time. All these factors influence driving safety.
