Do You Need to Wait for a Traffic Light When Making a U-Turn?

If there is a U-turn signal light and it is red, you must wait to make a U-turn. Otherwise, it will be considered running a red light, and according to the "Road Traffic Safety Law," you will be penalized with 6 points deducted and a fine of 200 yuan. If there is no U-turn signal light, and the gap is marked with a dashed line, the U-turn is not affected by the traffic signal and does not require crossing the pedestrian crossing. However, if the gap is marked with a solid line, the U-turn must cross the pedestrian crossing and is subject to the left-turn signal. Making a U-turn directly under such circumstances may result in being photographed or penalized by on-site traffic police. When making a U-turn that requires crossing the pedestrian crossing, you must yield to pedestrians: If pedestrians are walking on the right side of the crosswalk and have not reached the centerline of the road, vehicles on the left side of the road should slow down and allow them to pass safely. If pedestrians are waiting outside the boundary line of the motorized and non-motorized lanes and have not entered the road, vehicles should slow down and allow them to pass safely. If pedestrians cross the boundary line between the motorized and non-motorized lanes, vehicles that do not stop and yield are committing a violation and should be penalized. If pedestrians enter the motorized lane (Lane A) via the crosswalk, vehicles in Lane B should slow down and allow them to pass safely. If vehicles in Lane A do not stop and yield, it is a violation and should be penalized. If pedestrians are waiting at the centerline of the road without entering the motorized lane, vehicles that do not stop and yield are committing a violation and should be penalized. If pedestrians cross the centerline and enter the motorized lane, vehicles that do not stop and yield are committing a violation and should be penalized. If the road is divided by a green belt and pedestrians are waiting in the central stopping area, vehicles must slow down and allow them to pass safely. Cases where U-turns are allowed: If there is a U-turn sign at the intersection, you can make a U-turn. If there is a U-turn signal light, follow its instructions. If there is no signal light, make the U-turn without obstructing other vehicles or pedestrians. If the intersection does not explicitly prohibit U-turns or left turns, you can make a U-turn. "No explicit prohibition" means there are no "No U-turn" or "No Left Turn" signs, and the centerline is not solid. U-turns are also allowed on yellow grid lines. Yellow grid lines are no-parking zones at intersections prone to congestion. While stopping on them is prohibited, U-turns are allowed unless there is a central barrier. If there is a U-turn signal light, follow it—only make a U-turn when it is green. If "No Left Turn" and "U-turn Allowed" signs appear together, U-turns are allowed, but left turns are prohibited. Note that "No U-turn" is not the same as "No Left Turn." Precautions when making a U-turn at an intersection: Check the road markings. If they are solid lines, U-turns are prohibited under any circumstances. Continue driving to find a suitable spot. If there is a "No Left Turn" sign, U-turns are also prohibited at that intersection, as U-turns inherently involve a left turn. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, U-turns are not allowed. Always yield to straight-moving vehicles. If you interfere with their right of way, you will bear full responsibility for any accident. Near the stop line, lanes often have guiding arrows. The leftmost lane may not always have a left-turn arrow—if it has a straight arrow, U-turns are prohibited even if there are no explicit signs.

How to Repair a Cracked Windshield?

Windshield crack repair method: 1. First, attach a small mirror to the inside of the glass to better reflect the condition of the crack; 2. Place a triangular suction cup on the glass, aligning the center of the suction cup with the impact point of the crack. Then, slowly position and align the vacuum injector with the damaged point on the glass. Use the vacuum function of the tool to first extract any residual air inside the damaged point, then apply pressure to inject the resin from the repair tool into the damaged point of the glass; 3. Pull up the lever of the vacuum injector and wait for 5 to 10 minutes, closely observing the small mirror for any bubbles. If no more bubbles appear, it indicates that the air inside the crack has been completely extracted. If bubbles continue to appear, wait longer; 4. Lower the lever. At this point, observe from the inside of the glass to clearly see the flow of the repair resin gradually covering the damaged point; 5. After the adhesive fully enters the crack, remove the repair tool. Then, cover the repaired area with a transparent plastic film and use a UV lamp to quickly cure the repair resin; 6. Once the resin has solidified, remove the UV lamp and peel off the transparent plastic film. Use a wallpaper scraper to gently remove any excess resin remaining on the glass, leveling it out to complete the windshield repair process.

How to Use Car Lights Safely?

Methods for safely using car lights: 1. Position lights: Also known as clearance lights, position lights are used during evening driving to allow other drivers to judge the size and width of the vehicle ahead; 2. Low beam: The low beam and high beam of a vehicle are collectively referred to as headlights. The original vehicle's low and high beams cannot be turned on simultaneously. According to requirements, the vehicle's lights should be turned on along with the street lights, meaning that when street lights are on, the low beam must be turned on. The low beam has an illumination distance of about 30 to 40 meters; 3. High beam: The high beam has a higher angle of illumination, thus covering a longer distance, with more concentrated and brighter light. In principle, high beams should only be used when there are no lighting facilities and no oncoming vehicles. Otherwise, it can severely interfere with the vision of other drivers and even cause traffic accidents; 4. Turn signals: Turn signals are used to indicate that the vehicle needs to turn. When turning, the turn signal must be activated in advance, and the turn should only be made after confirming there are no vehicles approaching from behind. Never turn immediately after signaling without checking the rear situation. When overtaking, activate the left turn signal in advance and only overtake after confirming it is safe. If a vehicle behind intends to overtake, you can indicate by activating the right turn signal to allow it to pass.

What is the situation when there is abnormal noise in the rear axle of the car?

The situations when there is abnormal noise in the rear axle of the car are: 1. Insufficient gear oil or decreased viscosity: If caused by such reasons, it can be improved by changing the oil, adding sufficient oil quantity, or switching from multi-grade oil to single-grade oil, or using oil with a higher viscosity grade; 2. Abnormal noise caused by improper bearing clearance: If the bearing clearance is too small, there will be a relatively uniform continuous sound, while if the clearance is too large, there will be chaotic abnormal noise, which increases with the speed of the car; 3. Abnormal noise caused by gear tooth surface damage: If the tooth surface of the bevel gear is severely damaged, the wear exceeds the limit, or the clearance is too large, there will be abnormal noise during driving, along with metal friction sounds. The noise increases with the speed of the car, and when coasting in neutral, the noise significantly weakens or disappears, indicating severe tooth surface damage or broken teeth.

What Does Tire Cupping Mean?

Tire cupping refers to the abnormal and severe wear on the inner or outer edges of one or more tires. The primary cause of tire cupping is incorrect wheel alignment data, which requires a four-wheel alignment adjustment. Otherwise, it will affect the tire's lifespan and compromise safe driving. The reasons for tire cupping include: 1. Inaccurate four-wheel alignment, leading to cupping when wheels on the same side operate or front and rear wheels are misaligned, causing abnormal friction and accelerated wear on specific tire areas due to vehicle self-correction; 2. Incorrect toe adjustment can also cause cupping—front wheels are slightly tilted inward at a toe-in angle, which is optimal for high-speed stability. All vehicles have their own toe angle, and improper adjustment can result in cupping; 3. Steering gear failure may also lead to cupping or pulling; 4. Uneven or deformed chassis can cause abnormal tire wear; 5. Mixing tires of different specifications or having significantly uneven tire pressure can result in cupping.
