This situation constitutes a traffic violation, categorized as 'failing to enter the guiding lane in the required direction of travel.' Traffic police can impose a fine and deduct 2 points from the driver's license. If an intersection only has a U-turn lane and no left-turn lane, it may be because the road intended for left turns is a one-way street or prohibited from entry, making a left turn a violation. Situations where vehicles cannot make a U-turn: 1. Presence of a 'No U-Turn' sign: U-turns are strictly prohibited at intersections with this sign, and violations captured by cameras will result in point deductions and fines. 2. Presence of a 'No Left Turn' sign: Since U-turns generally require the use of the left-turn lane, a 'No Left Turn' sign also implies that U-turns are not allowed. However, if an intersection has both a 'No Left Turn' sign and a clear 'U-Turn Allowed' sign, then U-turns are permitted. 3. The leftmost lane has a straight arrow: Some intersections may not have signs prohibiting U-turns, but if the lane is marked with a straight arrow, it means the lane is for straight-through traffic only, and U-turns are not allowed at such intersections.

I've been driving for 20 years, and encountering intersections where you can only make a U-turn or left turn is actually quite common. The key is to anticipate the road conditions in advance, slow down as you approach the intersection, and observe the ground arrow markings and signs. Once you confirm that only a left turn or U-turn is allowed, immediately turn on your left turn signal and check the rearview mirror for vehicles behind you. It's especially important to note that some intersections require you to cross the pedestrian crossing to make a U-turn, so remember to check the pedestrian signal in advance. If you happen to be in the wrong lane, never force your way straight; it's better to make a left turn first and then find a safe place to turn around. Developing the habit of checking lane prompts when using navigation is crucial, as it can help you avoid many awkward situations.

Last night when I was driving my kid to tutoring class, I encountered this exact situation - the T-intersection at the downtown commercial street suddenly became left-turn only for U-turns. Here's what I did: First, ensure safety by slowing down to about 20 km/h, checking that no electric bikes would suddenly dart out from the left. After turning on the left signal, I found it more stable to steer slightly right before making the left turn. When making the U-turn, remember to take a wide arc rather than cutting it short - if you need to turn the steering wheel fully, it's best to keep it within 90 degrees. During rush hour when there's heavy traffic and long queues, don't rush to change lanes or cut in line; the safest approach is to follow the car ahead patiently.

Novice drivers often panic when encountering such road sections, but the principle is actually quite simple. Being only allowed to make a U-turn or left turn indicates that this section has been designated by traffic authorities as a specific flow lane, possibly due to a one-way street or construction ahead. There are three key points to remember when operating: check the signs 50 meters in advance and merge into the correct lane before the solid line; pay special attention to the blind spot of the inner A-pillar when making a left turn or U-turn; if it's an intersection with traffic lights, ensure that a U-turn on red does not affect vehicles going straight. Keeping the turning speed below 15 mph is safer.

Last time I went to the suburbs, I encountered this kind of road section. The navigation clearly showed to go straight, but the on-site signs only allowed a left turn. My coping experience is to first drive slowly in the leftmost lane, turn on the hazard lights to alert the vehicles behind. Make sure to stop and observe at the dashed line when it's safe, and never change lanes at the solid line. When making a U-turn, it's recommended to turn the steering wheel 180 degrees to leave enough turning radius for the rear wheels. If visibility is poor at night, it's best to get out of the car to check the road conditions ahead, especially paying attention to potholes on unfamiliar roads.
