Falling asleep or not paying attention when you are handling any kind of motorized vehicle can be dangerous, but doing so on a scooter bike and not wearing a protective helmet on your head can prove deadly.
The young woman featured in this dashcam video, reportedly from Russia, appears to have dozed off for a second or two on the bike and veered off her lane.
Luckily for her, the driver of the oncoming truck from the other lane saw her and made a quick maneuver at the last second avoiding a deadly head-on collision.
The woman hit her head on the side of the lorry and fell down from the motorcycle, but all told, she should feel extremely fortunate for living another day to tell the tale.
