The invention relates to a pre-warning type road height limiting frame with a pressure spring. The pre-warning type road height limiting frame consists of a road height limiting frame and a set of warning devices which are combined, wherein a door opening of the road height limiting frame is 20cm higher than a door opening of a conventional road height limiting frame; and the warning device is a seesaw type component and is assembled to the top of a crossbeam of the height limiting frame, a spring loop bar is mounted on the lower side surface of the tail end of the component located at a vehicle conveying end, a through hole for the spring loop bar to move is formed in the tail end of a support plate corresponding to the spring loop bar, and the spring loop bar is sleeved with the pressure spring. The height from the lower bottom surface of a vertical plate body in a vehicle driving direction to the ground is equal to the height of the door frame of the conventional road height limiting frame, so that when a vehicle with a vehicle body not 20cm higher than the door opening of the height limiting frame intrudes into the region of the height limiting frame accidently, the vehicle can be warned, so that the series of traffic accidents of damage of the vehicle, falling of the frame, even road paralysis and the like can be avoided.
