what occurs when a driver

begins operating a vehicle in an extremely drowsy, trance-like state. This typically occurs while driving on highways for an extended amount of time, and it can make the driver less aware of sudden changes in roadway conditions:
Velocitation
Carbon monoxide poisoning
Highway hypnosis
Stress

Highway hypnosis occurs when a driver enters a trance-like state while driving for an extended period of time. This can lead to decreased awareness of sudden changes in roadway conditions, increasing the risk of accidents. It is important for drivers to take breaks, stay alert, and avoid driving when excessively fatigued to reduce the risk of highway hypnosis. Carbon monoxide poisoning and stress can also negatively affect a driver's ability to operate a vehicle safely, but they are not directly related to highway hypnosis.
