Should I Shift to Neutral at Traffic Lights?

Do You Need to Turn on A/C for Car Air Conditioning Cooling?

To cool the car air conditioning, you must turn on the A/C switch; otherwise, only the blower will be working, and the air from the vents will be at normal temperature. The A/C switch in the car is the air conditioning control switch, which essentially controls the compressor. Its function is to activate the car's air conditioning cooling system. Steps for cooling with car air conditioning: First, press the A/C switch—the A/C light will turn on, indicating the cooling system is working. Next, press the recirculation button to cut off the exchange of air between the cabin and the outside. Then, adjust the temperature control knob to the desired cabin temperature. Improving cooling efficiency: Before driving, open all car doors. Start the engine, turn on the air conditioning, and switch to external air circulation with the fan at maximum speed (but do not turn on the A/C switch). Allow the airflow to replace the stale air inside the car for 2-3 minutes before getting in and closing the doors and windows. Then, activate recirculation and turn on the A/C switch for cooling. Additionally, you can use certain physical principles to enhance cooling efficiency. For example, based on the principle of air convection—hot air rises while cold air sinks—adjust the air vents to face slightly upward. This way, the rising hot air and descending cold air will help cool the cabin more quickly. Also, avoid placing decorations near the air vents, as they may obstruct airflow and reduce cooling effectiveness.

What does it mean when the EPC light comes on in a car?

The EPC indicator light can illuminate in two scenarios: during the power-on self-test and under other conditions. The power-on self-test is an indication that the vehicle is checking the status of all sensors before driving. Generally, if the engine is not started after powering on, the light will turn off by itself after about 3 seconds. However, if the EPC light remains on after the vehicle starts or illuminates under other circumstances, the possible causes include faults in the engine intake system, throttle issues, fuel system problems, engine malfunctions, ECU control unit failures, brake light issues, or anti-theft system faults. Below is a detailed explanation of the reasons for the EPC light coming on under other conditions and their solutions: Engine intake system fault: The EPC light may illuminate if the engine intake is obstructed or insufficient. Solution: Open the intake manifold switch valve cover, place a listening rod against the switch valve, and repeatedly press the accelerator pedal while starting the engine to clear any blockages. Throttle fault: Carbon buildup is a common issue with the throttle, and dirt accumulation can also affect intake, triggering the indicator light. Solution: Remove the throttle position sensor and install a new one on the throttle. Fuel system fault: Issues such as substandard fuel, fuel deterioration, or poor fuel atomization can cause the EPC light to come on. Solution: Use the appropriate fuel grade for the vehicle. Engine fault: Insufficient engine pressure or problems with components like the intake valve can also trigger the EPC light. Solution: Clean carbon deposits from the affected areas. ECU control unit fault: Interference with the vehicle's computer signals or false alarms from the computer can cause the EPC light to illuminate. Solution: Reprogram the ECU with the correct data. Brake light fault: If the brake lights fail, the brake switch malfunctions, or there is a wiring issue, the EPC light may come on. Solution: Visit a repair shop or dealership to replace the brake lights. Anti-theft system fault: If the electronic anti-theft system malfunctions or the anti-theft controller does not match the engine electronic controller, the EPC light may illuminate. Solution: Seek professional assistance at a repair shop, as this issue cannot be fixed individually. If the EPC light comes on, the driver can first try turning off the engine and restarting it to see if the light remains on. If it does not, the issue may have been temporary. However, if the light stays on or frequently illuminates, the vehicle should be taken to the nearest repair facility for professional diagnosis and timely resolution of potential safety hazards. The full English name of EPC is Electronic-Power-Control, which translates to electronic power control. Most people refer to it as the engine electronic stability system. The EPC system primarily includes controllers and sensors related to the powertrain. When sensor data is abnormal, the EPC system takes predefined actions to address the issue. Common EPC indicator lights are typically displayed in two colors: yellow and red. A yellow EPC light indicates a fault, but the vehicle can still be driven slowly to a repair shop. A red EPC light signifies a more serious issue, requiring immediate stopping of the vehicle and contacting a professional for repairs. Continuing to drive with a red EPC light can severely damage the vehicle's core components or compromise safety.

Can I Transfer to Another Driving School in a Different Location?

It is possible to transfer to another driving school in a different location, but specific regulations may vary depending on local traffic laws. For example, in Shenzhen, the "One-Certificate Nationwide Exam" policy is implemented, allowing mainland Chinese residents to apply for a small car driver's license with just their ID card at any location nationwide, without needing to submit a residence permit. Transferring to a new driving school requires additional payment: Since the new driving school is not affiliated with the original one, you will need to pay new training/registration fees. Enrolling in a new driving school means using their resources, such as vehicles and instructors, so fees are naturally incurred. However, it is worth noting that any subjects already passed at the original driving school will remain valid after the transfer and do not need to be retaken. Points to note when applying for a refund from the original driving school: Be sure to keep the original invoices and the contract signed during registration. If these documents are lost, the driving school will generally not issue a refund. You can first try negotiating with the school. If negotiations fail, you can call 12328 to file a complaint or report the issue to the local transportation authority's management office.

Can You Drive When the Small Sailboat Indicator Light Is On?

When the small sailboat light is red, you cannot drive; when it is blue, you can drive. The small sailboat indicator light is used to monitor the temperature of the engine coolant. If the red light is on, it indicates that the engine coolant temperature is too high, and continuing to drive could be dangerous. Reasons why the small sailboat indicator light may turn on: There is a leak in the engine area, causing a shortage of antifreeze in the engine cooling system. This situation occurs due to pipe damage or water pump leakage. A malfunction in the engine thermostat prevents the coolant from circulating properly inside the engine, leading to excessively high coolant temperature. A faulty engine cooling fan prevents the coolant from dissipating heat normally, causing the temperature to rise and the small sailboat light to turn on. If the engine water pump is not rotating smoothly, the coolant cannot flow properly, resulting in high coolant temperature and the water temperature light turning on. Small sailboat light is blue: This is normal. Blue indicates that the current coolant temperature is too low. After driving for a while, the water temperature will return to normal, and the small sailboat indicator light will turn off automatically. Higher chance of the red light turning on in summer: Due to the high temperatures in summer, the car's surface absorbs a lot of heat, and the temperature inside the engine system also rises. As a result, the coolant temperature tends to be higher, increasing the likelihood of the small sailboat indicator light turning on. However, the small sailboat light turning on is not only related to external temperature; wear and tear on the car itself can also cause abnormal coolant flow in the engine, leading to the small sailboat indicator light turning on.

Can a Motorcycle License and a Car License Not Be Combined?

Motorcycle licenses and car licenses must be combined. The training department will actively request the driver's license, and once the exams are passed, the two licenses can be merged. For those who already have a car driver's license and want to obtain a motorcycle license: First, the car driver's license must have passed the probationary period, and there should be no record of accumulating 12 penalty points in the previous and current scoring cycles before applying for the additional license. Then, an application for an additional license must be submitted to the local vehicle management office where the driver's license was issued, requesting to add the motorcycle driving category. After passing all the motorcycle license exams, the vehicle management office will revoke the original license and issue a new combined license. Process for applying for an additional license: The applicant submits a locally valid motor vehicle driver's license and other required documents to the driving school, fills out the application form, and passes a medical examination. After reviewing the documents submitted by the driving school, the vehicle management office will accept the additional license application and issue an appointment notice for the first written test. The applicant attends the first written test at the designated time. The applicant then undergoes driving skill training at the driving school. The driving school will coordinate the scheduling for the second and third practical tests and organize applicants to attend these tests at the vehicle management office. Within two working days after passing the exams, the vehicle management office will issue the motor vehicle driver's license, which can be collected at the driving school or delivered via express mail.

Is it acceptable if the rearview mirror crosses the line during reverse parking?

Generally, crossing the line with the rearview mirror during the reverse parking test in the driving exam does not result in a deduction, but this depends on the specific markings at each test site. According to the "Motor Vehicle Driver Training and Examination Syllabus," as long as the vehicle body does not exceed the ground markings during reverse parking, no points will be deducted. Since rearview mirrors are protruding, whether they are considered part of the vehicle body depends on how each test site identifies them. Failing the test occurs if the vehicle body crosses the line, fails to enter the parking space, stops midway, does not follow the prescribed route or sequence, or exceeds the allotted time. The full score for the test is 100 points, with evaluation criteria set for failing, deducting 20 points, 10 points, or 5 points. The rules for the second subject of the motor vehicle driving license exam state that any of the following will result in failure: stopping midway, rolling back, not following voice instructions, or having wheels or the vehicle body cross the line. Many students encounter line-crossing issues during the second subject test, with "crossing the line" being the most common reason for failure. The main cause of wheel line-crossing is students not mastering the correct timing for steering. Besides missing the right moment to steer, another reason could be the steering speed not matching the vehicle's speed. Subject 2 Deduction Standards: Not wearing a seatbelt: deduct 100 points. Starting the engine without the gear in neutral: deduct 100 points. Not using turn signals (including when starting, changing lanes, overtaking, turning, or parking); using turn signals for less than three seconds (this is easily overlooked!); forgetting to turn off turn signals or using them incorrectly: deduct 10 points. Stalling once: deduct 10 points. Reverse Parking: Not following the prescribed route sequence: deduct 100 points. Vehicle body crossing the line: deduct 100 points. Failing to enter the parking space: deduct 100 points. Before reversing, if both front wheels do not pass the control line: deduct 100 points. Exceeding the 210-second time limit: deduct 100 points. Stopping for more than 2 seconds: deduct 5 points each time. Slope Parking and Starting: After stopping, if the front bumper is not aligned with the pole line and exceeds 50 cm forward or backward: deduct 100 points. After stopping, if the front bumper is not aligned with the pole line but does not exceed 50 cm forward or backward: deduct 10 points. After stopping, if starting takes more than 30 seconds: deduct 100 points. Wheels crossing the road edge line while driving: deduct 100 points. Rolling back more than 30 cm when starting: deduct 100 points. After stopping, if the vehicle body is more than 50 cm from the road edge line: deduct 100 points. Not engaging the parking brake after stopping: deduct 10 points per occurrence. After stopping, if the vehicle body is more than 30 cm but less than 50 cm from the road edge line: deduct 10 points per occurrence. Rolling back more than 10 cm but less than 30 cm when starting: deduct 5 points per occurrence. Parallel Parking: After parking, if the vehicle body crosses the line: deduct 100 points. Not using or incorrectly using turn signals when entering the parking space: deduct 10 points. Exceeding the 90-second time limit: deduct 100 points. Touching the parking space edge line while driving: deduct 10 points per occurrence. Wheels touching the lane edge line while driving: deduct 10 points per occurrence. Stopping for more than 2 seconds: deduct 5 points per occurrence. 90-Degree Turn: Wheels crossing the road edge line: deduct 100 points. Not using or incorrectly using turn signals during the turn or not turning them off afterward: deduct 10 points. Stopping for more than 2 seconds: deduct 5 points per occurrence. Curve Driving: Wheels crossing the road edge line: deduct 100 points. Stopping for more than 2 seconds: deduct 100 points. Driving without shifting to second gear or higher: deduct 5 points.
