Children in surrounding towns and villages like to squat and play together at intersections and roadsides, which easily leads to rampage, sudden acceleration, U-turn in the middle and accidents with passing vehicles. Due to the poor lighting conditions when some national highways and provincial highways pass through villages and towns, the driver's vision at night becomes very narrow, and the sight distance is greatly shortened, which is prone to traffic accidents. When driving through grade crossing, we should adhere to the principle of "slow down, watch and pass", that is, we should slow down, carefully observe the surrounding situation, stop to watch when necessary, and honk the horn to ensure safety before driving through.
