When exiting a motorway, it can be difficult to accurately assess your own speed.

This is because it is easy to become a bit speed blind after driving on the highway for a while. Speed blind is when one underestimates their speed and typically occurs on large, monotonous roads, with high speed.

Without sufficient lighting, it becomes more difficult to perceive details and distance, complicating the assessment of speed. The same applies when evaluating smaller road users, such as mopeds and motorcycles.
