It is not allowed to cross the solid line when making a left-turn U-turn. Generally, on major traffic routes, double yellow solid lines are painted in the middle of the lanes, and vehicles crossing these double yellow lines will be fined and penalized with points. This is because at such road intersections, there is a high volume of traffic, and failing to strictly adhere to traffic rules can easily lead to accidents and cause road congestion. The relevant details are as follows: Conditions under which U-turns are allowed: Presence of U-turn signal or sign: At intersections with U-turn signals, a U-turn is permitted when the U-turn signal is green; if there is a U-turn sign or a lane marking indicating U-turns is present, a U-turn can be made ensuring the safety of oneself and others. No U-turn sign but left turns are allowed (no prohibition of U-turn signs or markings): Vehicles can make a U-turn at intersections where left turns are permitted and there are no signs or markings prohibiting U-turns. It is important to note that the vehicle must proceed according to the left-turn lane signal without affecting the normal flow of other vehicles. If making a U-turn at an intersection with a left-turn waiting area, the vehicle can first enter the waiting area when the straight signal is green and wait until the left-turn signal turns green to make the U-turn. U-turns are allowed at dashed lines: Whether it is a white or yellow dashed line, U-turns are permitted. If it is a double yellow line with one solid and one dashed, check if your side is the dashed line; if so, a U-turn is allowed safely; if it is a solid line, U-turns are not permitted. At intersections with double yellow lines (one solid and one dashed), U-turns can be made on the dashed line side, but the vehicle must not cross the stop line ahead. U-turns are allowed at yellow grid lines: Parking is prohibited in yellow grid line areas, but as long as there is no central barrier, a U-turn can be made here after yielding to normally moving vehicles.

You must never cross the solid line when making a U-turn by turning left, as this is a fundamental traffic rule. Solid lines indicate no lane changes or crossing, and violating this can easily lead to accidents. If you cross the solid line while turning left for a U-turn, you may disrupt the path of oncoming straight-moving vehicles, increasing the risk of sideswipes or rear-end collisions. Especially on urban main roads during peak hours with heavy traffic, crossing solid lines may also be caught by surveillance cameras, resulting in fines. With years of driving experience, I emphasize safety first: always observe road markings before making a U-turn and only perform the maneuver in dashed-line areas or zones where U-turns are permitted. If you can't find a suitable spot, detour or use an intersection with traffic signals. Developing good habits can prevent accidents and ensure every trip is safe and smooth. Don’t take risks just to save time! Remember: road safety depends on attention to every detail.

How long after the vehicle inspection can it be checked on 12123?

It can be checked on 12123 72 hours after the vehicle inspection. Introduction to vehicle inspection: The traffic police department conducts an annual inspection of the vehicle's condition and performance, also known as the annual inspection. New vehicles are inspected every two years. Contents of the vehicle inspection: Check whether the engine, chassis, body, and auxiliary equipment are clean, complete, and effective, whether the paint surface is uniform and aesthetically pleasing, and whether the main assemblies have been replaced. Verify whether it matches the initial inspection record; Check whether the vehicle's braking performance, steering control, lighting, exhaust, and other safety performance meet the technical requirements for safe operation of motor vehicles; Check whether the vehicle has been modified, remodeled, or transformed, whether the driving license, license plate, and vehicle file records match the current vehicle condition, whether there are any changes, whether approval and modification procedures have been completed, and whether the license plate, driving license, and enlarged license plate markings on the vehicle are damaged, altered, or unclear, and whether they need to be replaced.

What is the HOLD light?

HOLD light is the gear lock indicator light. When the HOLD light is on, it indicates that the gear is locked in a specific position. When driving uphill or on icy/snowy roads that require low-gear operation, you can activate HOLD to lock the transmission in second gear. The button for this switch is located in the middle of the gear lever. Pressing it again will deactivate the function. Normally, it's not recommended to use this feature as it may harm the transmission. Automatic gear lock is a forced downshift key, used when gears get stuck or during towing. When HOLD is activated, the parking brake system will automatically engage each time the vehicle comes to a complete stop after braking. You'll feel a release of pressure on the brake pedal, at which point you can release the pedal without worrying about the vehicle rolling. Working principle of gear lock indicator light: The transmission control unit uses this sensor to detect the gear selected by the driver and performs corresponding control actions. Relationship between neutral switch and gear position switch: In older vehicles, the P (Park) and N (Neutral) switches were connected in series with the starter motor switch, meaning the engine could only be started in these two positions. In newer vehicles, the control unit identifies the neutral signal first, then decides whether to engage the starter motor.

What Causes Engine Shaking When Warm?

Here are the specific reasons for engine shaking during warm idle: 1. Fuel system issues: Typically caused by fuel line blockages leading to poor fuel supply, manifested as engine shaking, unstable idle, or stalling while driving. Fuel pump failure can also cause engine shaking. To diagnose fuel pump problems, disconnect the fuel line and check fuel flow rate and volume. 2. Electrical system issues: Check whether spark plugs are worn, if gaps are uniform, or if gaps have changed. Additionally, malfunctioning distributors can cause engine shaking. 3. Mechanical reasons: Inspect engine operation for abnormal sounds or valve noise. Check belt condition for looseness.

What Causes Difficulty in Removing the Car Key?

Car key difficulty in removal can be attributed to the following reasons: 1. P gear not properly engaged: When exiting the vehicle, the gear was not shifted to P or the P gear did not fully engage, possibly obstructed by an object, thus failing to trigger the electronic sensor. 2. Steering wheel locked: The steering wheel was not returned to its proper position when parking, causing an abnormal lock. The solution is to insert the key, attempt to turn the steering wheel left and right while twisting the key, which will release the steering wheel lock. 3. Obstruction in the key slot: The solution involves removing the obstruction, starting the car, shifting the gear again to ensure it is fully engaged, after which the key can be removed.
