Reverse driving is an act of driving on the roadway opposite to the specified vehicle traffic direction, and driving in the opposite direction rather than the normal direction. Reverse driving refers to all situations in which the vehicle travels on a road in a direction different from the direction of the designated driving lane, so the cases are diverse. The most common is center line violation, which can range from inability to maintain a normal lane, such as drowsy driving or drunk driving, to crossing the lane trying to avoid an obstacle or accident. If there is a designated overtaking section on a round-trip two-lane road, crossing the lane for the purpose of overtaking there is not reverse driving.

Over the past three years ('18~'20), there have been about 97 confirmed reverse driving accidents in Gangwon-do, and 9 traffic accidents, resulting in 3 fatalities and 7 injuries. Traffic accidents caused by reverse driving are very serious. Specifically, the fatality rate from reverse driving is 14 times higher than for forward driving. For this reason, social interest in reverse running issue and reverse running prevention is increasing, and it is very necessary to supplement and strengthen safety facilities to prevent reverse running.
