The invention relates to a vehicle electronic warning board system, a road condition early-warning system and a working method thereof. The vehicle electronic warning board system comprises a laser emitting device used for projecting a warning pattern on the road behind a vehicle; an orientation adjustment device used for adjusting the location of the laser projection pattern; and a control unit connected with the laser emitting device and the orientation adjustment device. The control unit is used for controlling the on/off state of the vehicle electronic warning board system and is used for controlling the orientation adjustment device and the laser emitting device to project the warning pattern at an appropriate distance from the parked vehicle on the road behind the vehicle. According to the technical scheme of the invention, based on the vehicle electronic warning board system and the working method thereof, after the occurrence of a vehicle fault, no warning board needs to be manually placed. Meanwhile, the warning pattern and the voice warning are projected on the road behind the vehicle at a fixed distance from the vehicle. Therefore, the occurrence of secondary traffic accidents is avoided.
