In order to rule overload and oversize transportation, regulate the produce of vehicles, mandatory standard GB 1589-2004 "Limits of dimensions, axle load and masses for road vehicles" was promulgated and implemented in China. With the implement of standard GB 1589-2004, it achieved the expected result. However, with the improvement of vehicle technology, road and the facilities, related technical regulations should more closely conform to international regulations. Besides, some factors which didn't meet actual situations were found after the implement of this standard. A comparative analysis was discussed in this paper about the dimensions, axle load and masses of vehicle in order to make the standard more suitable for road transport's actual needs, road facilities' requirements at home and abroad. Finally, this paper puts forward opinions and suggestions which will be useful for the revision of the standard.
