The invention provides a road traffic accident in-situ warning unit with a distance reminding function, comprising a front early warning device and a rear warning device. The front early warning device is used for being disposed on a front warning line of a warning area. The rear warning device is used for being distributed an accident site in the warning area. Both the front early warning device and the rear warning device are provided with satellite positioning modules and interact with each other for their satellite positioning data in a wireless communication manner. At least one of the front early warning device and the rear warning device can calculate their distance parameter according to the satellite positioning data and makes a corresponding distance reminder through a distance reminding module. The road traffic accident in-situ warning unit is capable of quickly and conveniently measuring a distance between the front warning lien set on a traffic site and rear staff and reminding of whether the warning area set by the staff on the road meets the specified requirements, thus causalities caused by insufficiency of the distance set in the warning area are decreased.
