The invention provides a road condition monitoring and safety protection method which is applicable to a safety belt and an electric retractor used for retraction of the safety belt. The method includes the steps: detecting the distances of vehicles by range radars arranged on front and rear bumpers and side door posts of the vehicles, and outputting ranging signals; converting the ranging signals into digital signals; comparing the ranging signals with a reference value, and outputting comparison results; starting and stopping a vibrator mounted below a driver seat according to the comparison results, and enabling the vibrator to generate high-frequency low-amplitude vibrations when the ranging signals are smaller than the reference value; subjecting the ranging signals to acceleration detection by the aid of a virtual timer arranged in a controller, and controlling the electric retractor to retract the safety belt when the acceleration reaches a preset value.
