Answer
In general, a fatigue-related crash has some of the following characteristics [12] [15]:
- The vehicle ran off the road or bumped into a (stationary) car in front/object.
- The crash occurred on a road with a high speed limit.
- The crash occurred between midnight and dawn.
- There were no skid marks.
- The driver had a clear view of the road.
- There were no passengers in the vehicle.
- There are no other plausible explanations (such as alcohol use or indisposition).
In general, the outcome of a fatigue-related crash is serious, in particular because the impact speed is high as brakes are not used.
