What is a U-turn vehicle?
2 Answers
U-turn vehicles refer to ordinary vehicles that, during highway travel, have an entry toll station recorded on their pass that matches the current toll station. Such vehicles are termed U-turn vehicles. Correspondingly, there is also J-turn driving. Both of these behaviors are illegal, and highways in various regions impose different levels of penalties for them. More details are as follows: 1. Highway positioning: Highways are a type of road classified by technical grade, ranking above Class I, Class II, Class III, Class IV, and unclassified roads. Highways intersect with national or provincial highways in the road network hierarchy classification, meaning highways are part of the national or provincial highway network. 2. Highway driving precautions: When driving normally on a highway, vehicles in the same lane must maintain a sufficient safe distance based on speed, weather, and road conditions. Under normal conditions, when the speed is 100 km/h, the safe distance should be more than 100 meters; when the speed is below 100 km/h, the safe distance can be appropriately reduced, but the minimum distance should not be less than 50 meters.
U-shaped vehicles refer to models with a U-shaped body design, typically used in the commercial truck or engineering vehicle sector. I've seen many such vehicles busy at construction sites, where the U-shaped frame leaves the top of the cargo compartment wide open, allowing easy loading and unloading of goods from the sides or top, making them particularly suitable for transporting large equipment. The advantage lies in high space utilization, reducing the number of trips and saving time; however, the downside is a high drag coefficient, leading to significantly increased fuel consumption during high-speed cruising. Maintenance requires attention to whether the U-shaped chassis is balanced to avoid uneven force distribution causing component deformation. Related topics discuss practicality—compared to box trucks, U-shaped vehicles are less flexible in turning but offer stronger overall stability, especially performing well on rough terrain. Overall, this design is quite popular in the logistics industry, but daily driving requires attention to maintenance points.
