What kind of intersections allow U-turns without being controlled by red lights?

Intersections where U-turns are not controlled by red lights include: Straight-through intersections: Straight-through intersections only use one set of traffic lights. When the red light is on, straight-through traffic stops, and when the green light is on, straight-through traffic proceeds. For intersections that allow U-turns, U-turns can be made under both red and green lights. However, some places may specifically mark "U-turn on red" for safety reasons, in which case U-turns can only be made when the red light is on. It is important to note that if you see a "No U-turn" sign before the intersection, it means U-turns are prohibited at that intersection, and you must be careful not to violate traffic regulations. Cross intersections: Cross intersections are equipped with at least two sets of traffic lights, usually arrow-type. U-turning vehicles do not depend on the traffic light status (but at many intersections, straight-through vehicles need to cross the stop line, so they must follow the left-turn signal). When making a left turn, ensure safety; straight-through vehicles proceed according to the traffic lights (stop at red, go at green); right-turning vehicles do not depend on the traffic lights but must yield to straight-through vehicles.

Over the years of driving, I've encountered many intersections where you can safely make a U-turn without worrying about red lights. Usually, these places have dedicated U-turn zones, such as some T-intersections or wide road sections, with clear markings on the ground or signs allowing U-turns. Sometimes, there are even separate traffic lights specifically for U-turns—once the light turns green, you can go straight. There are also some simple intersections without any traffic lights, where you can make a U-turn freely, but you need to pay attention to oncoming traffic to ensure safety. I remember last time on a main road in the suburbs, there was an opening allowing drivers to make a U-turn anytime, unrestricted by regular traffic lights, which saved a lot of time. In short, it's a good habit to observe traffic signs more often, slow down before making a U-turn, and check the surroundings to avoid accidents. After all, rules vary by location, and safety comes first.

As a parent who often drives to pick up and drop off my kids, I pay special attention to intersection safety. Situations where U-turns can be made without waiting for a red light mainly occur at locations with clear signage, such as intersections with dedicated U-turn lanes or installed indicator signs. Sometimes, these are located near expressway entrances and exits. I've also noticed that some commercial areas or newly built roads have smarter designs, with U-turn points positioned away from main signal controls. It's essential to develop the habit of checking for no-U-turn signs or special instructions while driving, rather than relying on intuition, especially during nighttime when visibility is poor. From chatting with neighbors, I learned that traffic police in some areas may set up temporary U-turn points, but it's crucial to follow on-site instructions. Remember, safety is always the top priority—never rush or take risks.

As a young commuter, I have a basic understanding of these rules. U-turns without regard to traffic lights typically occur at intersections not covered by signals, such as simple crossings without traffic lights or roadside openings. Some road sections allow U-turns during a green light for straight traffic, provided there are markings or signs clearly indicating it. This design is commonly seen on urban expressway service roads to facilitate flexible turns for drivers. Just make it a habit to observe before acting to avoid fines for violations.

I'm quite obsessed with car culture and often discuss traffic details. U-turns not controlled by red lights are mostly at specially designed locations, such as some main road side openings with independent signals or even no-light zones. Engineers considered traffic efficiency during planning, not relying on main intersection signals. This is common near highway exits or large roundabouts, using buffer zones for isolation to reduce interference. Always check official signs while driving to ensure legality and avoid mistakenly running red lights and getting caught. Reasonable U-turns can save fuel and time, but keep up with the traffic flow. Learn traffic rules to improve driving skills, avoid risks, and make trips smoother.
