Can You Make a U-Turn at a Red Light?

If the U-turn signal is red, you must wait; otherwise, it will be considered running a red light. According to the Road Traffic Safety Law, this offense carries a penalty of 6 demerit points and a fine of 200 yuan. If there is no dedicated U-turn signal, and the gap in the lane is marked with a dashed line, the U-turn is not affected by traffic signals 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 without following these rules may result in being photographed by traffic cameras or penalized by on-site traffic police. When making a U-turn that requires crossing a pedestrian crossing, pedestrians must be given the right of way: 1. Pedestrians walking on the right side of the crosswalk who have not reached the centerline of the road: Vehicles on the left side must slow down and proceed only when it is safe to do so. 2. Pedestrians waiting outside the boundary of the motorized and non-motorized lanes, not yet entering the roadway: Vehicles should slow down and proceed only when safe. 3. Pedestrians crossing the boundary between motorized and non-motorized lanes: Failing to stop for them is a violation and punishable. 4. Pedestrians entering the motorized lane (Lane A) from the crosswalk: Vehicles in Lane B must slow down and proceed only when safe. Failing to yield is a violation. 5. Pedestrians waiting at the centerline of the road without entering the motorized lane: Failing to stop for them is a violation. 6. Pedestrians crossing the centerline into the motorized lane: Failing to yield is a violation. 7. Pedestrians separated by a median strip and waiting in the middle of the road: Vehicles must slow down and proceed only when safe. Permissible U-turn scenarios: 1. Intersections with U-turn signs: If there is a clear U-turn sign, you may proceed. If there is a U-turn signal, follow it. Without a signal, make the U-turn only if it does not interfere with other vehicles or pedestrians. 2. Intersections without explicit "No U-turn" or "No Left Turn" signs: U-turns are allowed unless prohibited by signs or solid centerlines. 3. Yellow grid lines: These indicate no-stopping zones, but U-turns are permitted unless there is a center divider. 4. Intersections with U-turn signals: Follow the signal—green means go. 5. When "No Left Turn" and "U-turn Allowed" signs coexist: U-turns are permitted, but left turns are not. Note that "No U-turn" does not necessarily mean "No Left Turn." Key considerations when making a U-turn: 1. Observe road markings: Never U-turn over solid lines; continue driving to find a suitable spot. 2. "No Left Turn" signs: Even if "No U-turn" is not explicitly stated, U-turns are prohibited because they involve a left turn. 3. U-turns must be made from the innermost left-turn lane. U-turns from the second left-turn lane are not allowed. 4. Always yield to oncoming traffic. Failing to do so makes you fully liable for any accidents. 5. Pay attention to lane arrows: The leftmost lane may not always be for left turns. If marked for straight traffic, U-turns are prohibited even without explicit signs.

What Does Original Equipment Manufacturer (OEM) Oil Mean?

Original Equipment Manufacturer (OEM) oil refers to lubricant products that are certified and authorized by the vehicle manufacturer, categorized into two types: "rebranded" and "exclusive supply". Here's an introduction: OEM oil is not actually produced by the "original factory", as most automobile manufacturers do not produce engine oil themselves, nor do they participate in its development process. Therefore, OEM oil is essentially lubricant supplied by the vehicle manufacturer for their cars, typically customized and manufactured by major oil companies on their behalf. Automakers do not produce their own engine oil. Here are some details about OEM oil: In terms of product composition, OEM oil can be classified into mineral oil, semi-synthetic, and full-synthetic oils. Different vehicle brands and series will have different OEM oils. However, fundamentally, there is little difference between OEM oil and commercial brand oils available in the market—they use the same base oils and additives, without any superior qualities.

At what RPM should the tachometer reach for starting on a slope?

Start the engine when the tachometer reaches around 1000 RPM during a slope start. If the engine stalls during a slope start, immediately press the brake to prevent the car from rolling backward, which could lead to failing the test or causing an accident. Remember to shift to neutral before restarting the engine. Tips for slope starts: During the slope start in the driving test (Subject 2), quickly press the brake and clutch when reaching the stop line. The slope start is part of the driving test (Subject 2), where the vehicle must start uphill from a steep slope. When learning manual transmission slope starts, follow these steps: first, pull the handbrake, press the accelerator to at least 2000 RPM, then release the clutch until it drops to around 1000 RPM, release the handbrake, slightly release the clutch while adding a bit of gas, and the car will naturally move uphill. Slope start mnemonic: Boarding mnemonic: Report, turn counterclockwise, report again, look around, board the car, hand over the ID, and perform five actions, start the car, and ask the examiner. Specific steps: "Report!" Walk around the car counterclockwise, then "Report!" Observe front and back, open the door, hand over the ID: "Report, teacher, here is my ID." Starting mnemonic: Left foot on, right hand shifts, turn signal, honk, observe left and right, release handbrake, slowly lift clutch and add gas. Specific steps: Left foot on the clutch, right hand shifts to first gear, turn the signal left (down) (at night: flash lights three times), honk 1-2 times, check mirrors left and right, release the handbrake, slowly lift the clutch and press the accelerator. (At night: When overtaking or meeting, flash lights twice).

Where Can You Find the Engine Manufacturing Date?

For most household cars, the engine nameplate can be found on the lower part of the passenger door. Simply open the door to locate it. If not found there, you can search around the engine area for the nameplate, which clearly displays the manufacturing date of the engine. In addition to the manufacturing date, the vehicle nameplate also provides information such as the engine model, power, torque, etc. The engine model refers to the identity assigned by the platform where the engine was developed. It can generally be divided into four parts: the prefix, middle section, suffix, and tail section, each with specific meanings: Prefix: Includes the product series code, generation symbol, and regional or manufacturer code. Manufacturers may choose corresponding letters as needed, but these must be approved and recorded by the industry standardization authority. Middle Section: Consists of symbols representing the number of cylinders, cylinder arrangement type, stroke, and cylinder diameter. Suffix: Comprises symbols indicating structural features and usage characteristics. Tail Section: A distinguishing symbol. When differentiation is required due to improvements or other reasons within the same series, manufacturers may select appropriate symbols. The suffix and tail section can be separated by a "-". Engine Power: Indicates the maximum power of the engine. Torque: Represents the maximum torque of the engine.

What principle does the reversing radar utilize?

The principle utilized by the reversing radar is: Based on the principle that bats can fly at high speeds in the dark without colliding with any obstacles, the reversing radar was designed and developed. The display of the reversing radar is installed on the rearview mirror, continuously reminding the driver of the distance to objects behind the vehicle. When reaching a dangerous distance, the buzzer starts to sound, alerting the driver to the proximity of obstacles and prompting timely stopping. Here is a brief introduction about the reversing radar: (1) The full name of the reversing radar is "Reverse Anti-Collision Radar," also known as "Parking Assistance Device," or referred to as the reverse computer warning system. (2) It is a safety assistance device for parking or reversing vehicles, consisting of ultrasonic sensors (commonly known as probes), a controller, and a display (or buzzer), among other components. (3) It can inform the driver about surrounding obstacles through sound or more intuitive displays, eliminating the troubles caused by the driver's need to look around when parking, reversing, or starting the vehicle. It also helps the driver overcome the shortcomings of blind spots and blurred vision, enhancing driving safety.
