What are the gear and speed standards for Subject 3?

Subject 3 gear and speed standards: 1st gear: 0-20km/h; 2nd gear: 5-30km/h; 3rd gear: 15-40km/h; 4th gear: 30-55km/h; The highest gear required in Subject 3 is fourth gear, which is shifted during straight-line driving. Below is an introduction to the content of the Subject 3 test: 1. The road driving skills test for Subject 3 generally includes: preparation for getting on the vehicle, simulated lighting test, starting, straight-line driving, gear shifting operations, lane changing, pulling over, passing through intersections straight, turning left at intersections, turning right at intersections, passing through pedestrian crossings, passing through school zones, passing through bus stops, meeting vehicles, overtaking, making U-turns, and night driving. 2. The safe and civilized driving knowledge test generally includes: requirements for safe and civilized driving operations, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations such as tire blowouts, and post-traffic accident handling knowledge.

What is a China 5 Vehicle?

China 5 vehicles refer to cars that meet the National Phase 5 Motor Vehicle Pollutant Emission Standards. Below are methods to check a vehicle's emission standard: Check the Vehicle Qualification Certificate: The emission standard of the vehicle is clearly stated in the vehicle qualification certificate. Check the Conformity Certificate: Provided when purchasing a new car, it includes exhaust emissions and indicates the corresponding emission standard. For example, if it shows GB18352.5-2013, GB18352 is the national standard for vehicle emissions, and the number 5 indicates that it meets the fifth phase, i.e., the China 5 emission standard. Inspect the Vehicle Environmental Protection Label: The vehicle emission standard is written on the back of the environmental protection label on the car's front windshield. You can also take the vehicle registration certificate to the vehicle management office to inquire about the vehicle's emission standard. Query on the Motor Vehicle Environmental Protection Website: Visit the official website of motor vehicle environmental protection, find the public query platform at the bottom of the homepage, enter the corresponding vehicle VIN code (chassis number), and the last 6 digits of the engine number to check. It's important to note that while relevant information can usually be found on the vehicle license, the license does not specify whether the vehicle is a China 5 or other standard.

What are the restrictions for out-of-town license plates in Shanghai?

Small passenger cars with license plates issued by other provinces or cities are prohibited from driving, including those with temporary license plates, unoccupied taxis, and cars driven by drivers in their probationary period (except on Saturdays, Sundays, and national holidays). The restricted hours for out-of-town license plates are from Monday to Friday, 7:00 AM–10:00 AM and 3:00 PM–8:00 PM. There are no restrictions on Saturdays, Sundays, or national holidays. Additional information: 1. Check tire surfaces before driving: Tire blowouts at high speeds are the most frequent and dangerous cause of traffic accidents. Therefore, before driving, be sure to inspect the wear on the tire surface, checking for bulges, cracks, or damage caused by sharp objects. If such issues exist, repair or maintenance should be performed before driving. 2. Replace problematic tires: If possible, remove the tires to inspect the inner side for damage, as hidden internal damage is often the main cause of accidents. If there’s no time for a thorough tire inspection and replacement, at least move problematic tires to the rear wheels to minimize the risk of accidents.

Can I travel without carrying a driver's license now that I have an electronic one?

With an electronic driver's license, you can travel without carrying a physical one, but this doesn't apply universally, as the electronic driver's license is currently only being piloted in certain cities and has not been implemented nationwide. In cities where the electronic driver's license has been implemented, you naturally don't need to carry a paper version, which is indeed good news for forgetful car owners. Relevant information about the driver's license is as follows: 1. Introduction: The People's Republic of China Motor Vehicle Driver's License, referred to as the driver's license or 'driving license,' is a certificate required by law for motor vehicle drivers in China. 2. Examination Content: The test subjects include traffic regulations and related knowledge, field driving, and road driving (including safe and civilized driving), totaling three items.

Do You Need to Press the Brake When Shifting to S Gear?

Automatic transmission does not require pressing the brake when shifting to S gear. The usage of S gear includes: during short-distance competitive races; when driving uphill, overtaking, or on rough roads; and when stronger traction is needed. Below are some tips on shifting gears: 1. Upshifting Techniques: Before upshifting, ensure the road ahead is clear. The throttle and clutch operate like a seesaw—do not press them simultaneously. Shift gently; generally, shifting up to fourth gear is sufficient, and fifth gear can be used if conditions allow. Upshifting must be done one gear at a time—skipping gears is not recommended. 2. Downshifting Techniques: To downshift, first reduce speed; to reduce speed, first apply the brakes. There is no need to downshift to first gear when stopping—stop in the current gear. Always start in first gear, but stopping does not require downshifting. For turns, use second gear; for U-turns, use first gear; for traffic lights, use third gear; and for pedestrian crossings, pass at around 30 km/h in third gear.

What is the measurement method for a two-wire crankshaft position sensor?

The measurement method for a two-wire crankshaft position sensor is as follows: 1. The engine speed signal comes from the crankshaft position sensor. If the sensor does not output a signal, the engine tachometer will not move. 2. Connect the two probes of a multimeter to the two signal wires of the crankshaft position sensor. Set the multimeter to the 20V range at idle speed. A higher measured voltage indicates a higher engine speed. 3. Adjust the oscilloscope voltage to 14V and the time to 10ms, then start the vehicle to observe the AC signal waveform. 4. Use a diagnostic scanner to read the engine speed data stream. The functions of the crankshaft position sensor include: 1. Detecting engine speed; 2. Detecting the top dead center position of the pistons; 3. Detecting and controlling the top dead center signals for each cylinder's ignition.
