Turn signals should be used as follows: 1. When overtaking, first activate the left turn signal, then use the right turn signal after completing the overtake. 2. Use the left turn signal when entering a highway. When exiting a highway, always turn right. No signal is needed when entering a roundabout, but the right turn signal must be used when exiting. 3. Use the right turn signal when pulling over to park. When leaving the roadside, always turn left, so use the left turn signal. 4. For U-turns, which are generally made to the left, use the left turn signal. Use the left signal for lane changes to the left, and the right signal for lane changes to the right. 5. Always activate the turn signal in advance when preparing to turn, giving following drivers adequate reaction time.

Can I switch to C2 after failing C1 Subject 2 four times?

C1 Subject 2 failing 4 times cannot be switched to C2 test, and the test content cannot be changed at will during the test; but after failing 5 times, you need to retake the Subject 1 test, at which time you can switch to the C2 test. The C1 test subjects include four items: traffic regulations and related knowledge, field driving, road driving, and safe and civilized driving knowledge. C1 driver's license test passing standards: Traffic regulations and related knowledge (Subject 1) - written test, full score is 100, 90 or above is passing. Field driving (Subject 2) - on-site, actual vehicle. The minimum requirement is 80 points, less than 80 points is failing. Road driving (Subject 3) - highway or simulated site, actual vehicle. Full score is 100, must reach 90 or above to pass. Safe and civilized driving knowledge - written test, questions are mainly in the form of cases, pictures, animations, etc., question types are judgment, single choice and multiple choice, a total of 50 questions, full score is 100, 90 is passing.

Can I directly add 95 gasoline when 98 gasoline is not completely used up?

It is possible to add 95 gasoline when 98 gasoline is not completely used up. Occasionally mixing them is acceptable, but it is not recommended to mix them frequently. You should choose between 98 and 95 gasoline based on the suitable gasoline grade for your vehicle. Here are the specific details: Gasoline grades represent the fuel's anti-knock performance. The higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 95 gasoline contains 95% isooctane and 5% n-heptane, while 98 gasoline contains 98% isooctane and 2% n-heptane. Anti-knock performance refers to the ability of gasoline to resist knocking when burning in the engine. It is the primary indicator of gasoline's combustion function. Knocking is caused by abnormal combustion of gasoline in the engine. The octane number is the target for gasoline's anti-knock performance. The higher the octane number, the stronger the anti-knock performance. Higher compression ratios and higher combustion chamber pressures make gasoline with lower anti-knock performance more prone to knocking. Occasionally using the wrong gasoline grade only requires switching back to the correct grade after use. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles that require lower-grade gasoline, using higher-grade gasoline will not cause damage, but the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This means the engine's power output and thermal efficiency will decrease, resulting in poorer performance. For vehicles that require higher-grade gasoline, using lower-grade gasoline can cause engine knocking. Because the octane number is too low, the fuel's ignition point decreases, causing premature ignition during the compression stroke. If the fuel ignites before the spark plug fires during the compression stroke, resistance will occur during the upward stroke. This resistance can make the engine run very unstable. If the knocking is imperceptible, it only increases noise and does not cause significant damage to the engine. However, if the knocking is noticeable, it indicates severe engine conditions. The vibration not only affects driving stability but also causes abnormal wear on the pistons and cylinders, and in severe cases, can lead to cylinder scoring.

What size photo is required for a driver's license?

Driver's license requires a 1-inch photo. Here is some information about driver's license photos: Source: The origin of photos used on driver's licenses varies from place to place. Some locations take the photo during the physical examination, some require it to be provided at the time of application, while others require applicants to submit it themselves after passing the subject four exam. Requirements: The photo must be a recent (within the last six months), bareheaded, color front-facing photo with a white background. White clothing and uniforms are not allowed. The photo does not need to include an ID number. The size must be 1 inch. Those who require vision correction must wear glasses. The head should occupy about two-thirds of the photo length. The photo must be clear and recognizable.

Will points be deducted for voluntarily changing lanes in Subject 3?

In Subject 3, you can voluntarily change lanes without point deductions, but the operation must comply with lane-changing regulations. Here are the details: Point Deductions: Normal lane changes will not result in point deductions. However, if you cross two consecutive motor vehicle lanes during a lane change, points will be deducted. When neither the examiner nor the driving computer issues an instruction, you can drive the vehicle based on road conditions. Note: When changing lanes, the driver should carefully observe traffic conditions. Lane changes should be performed decisively. Keeping the turn signal on for too long without changing lanes can lead to dangerous situations.

What is the difference between 5054a and 5054b?

Automotive diagnostic tools 5053 and 5054 are both specialized diagnostic devices for Volkswagen vehicles, offering powerful functionality in diagnosing Volkswagen cars. Here are the specific differences between the two: Different versions: 5053 is the older diagnostic tool; 5054 is the upgraded version of 5053 and 5053A, representing a more technologically advanced diagnostic tool in Volkswagen's specialized diagnostic lineup (with 5054A being even higher-end). Different diagnostic capabilities: 5053 can handle fault detection, fault reading, data analysis, component testing, and adjustment matching for newer Volkswagen vehicles with CANbus systems, but it does not support functions like immobilizer key matching or reading security codes; 5054 can diagnose (including matching) all issues currently present in Volkswagen vehicle models.

What does LIN bus mean in automobiles?

LIN bus is a low-cost serial communication network defined for automotive distributed electronic systems. Below is an introduction to LIN bus: 1. Definition: LIN bus is a low-cost serial communication network defined for automotive distributed electronic systems. It serves as a supplement to other automotive multiplex networks such as Controller Area Network (CAN) and is suitable for applications that do not require high bandwidth, performance, or fault tolerance. The LIN bus is based on the SCI (UART) data format and adopts a single-master/multi-slave mode, which is a special case of UART. 2. Working Principle of LIN Bus: The control units controlled by the LIN bus are generally distributed in a relatively close space. Data transmission is single-wire, and the maximum length of the data line can reach 40m. In the master node, a 1kΩ resistor is configured to terminate the 12V power supply, while in the slave nodes, a 30kΩ resistor is configured to terminate the 12V power supply. Each node supplies power to the bus through a resistor connected to the positive terminal of the battery, and each node can pull down the bus voltage through its internal transmitter.
