What Do You Need to Prepare for Riding a Motorcycle on the Highway?

To ride a motorcycle on the highway, you need to prepare a driver's license and a helmet, and the speed must not exceed 80 kilometers per hour. Wearing a Helmet: When riding on the highway, you must wear a helmet. This is a mandatory requirement under traffic safety laws. If you are caught riding without a helmet, you will be stopped and fined by traffic police. Additionally, carrying passengers on the highway is strictly prohibited. Speed Must Not Exceed 80 km/h: The speed of the motorcycle must not exceed 80 kilometers per hour, and you must ride on the right side of the road, maintaining a speed between 70 and 80 kilometers per hour. Exceeding this limit will result in penalties from traffic police. Possessing a Motorcycle Driver's License: You must have a valid motorcycle driver's license to ride on the highway. Although many people may not choose to obtain a motorcycle license, it is mandatory for highway riding. Using other types of motor vehicle licenses is not permitted. If caught driving without the proper license, you will face penalties, and in severe cases, may even have 12 points deducted from your license.

Do I Need to Drive the Car for New Vehicle Annual Inspection?

New vehicles need to be driven for annual inspection. Vehicle annual inspection refers to a mandatory test for every vehicle that has obtained an official license plate and registration certificate, equivalent to an annual physical examination for the vehicle according to the "Technical Conditions for Motor Vehicle Operation Safety." Inspection time requirements: Small and micro non-operational passenger vehicles are exempt from inspection for the first 6 years. After 6 years but less than 10 years, they must be inspected every two years; after 10 years but less than 15 years, they must be inspected annually; after 15 years, they must be inspected every 6 months. Operational passenger vehicles must be inspected annually within the first 5 years; after 5 years, they must be inspected every 6 months. Trucks and large and medium-sized non-operational passenger vehicles must be inspected annually within the first 10 years; after 10 years, they must be inspected every 6 months. Imported vehicles, like other vehicle types, can undergo regular inspections at any inspection station. Inspection precautions: Vehicles that fail the inspection must be repaired within a specified period. If they still fail after the deadline, the vehicle management office will confiscate their license plates and registration certificates, prohibiting further use. Vehicles that do not undergo inspection without reason or fail the inspection are not allowed to drive on the road or transfer ownership. Vehicles that meet the scrapping conditions or exceed the prescribed service life will not be inspected, and their license plates and registration certificates will be revoked, with their files canceled and the vehicles scrapped.

How to Display the Tire Pressure Monitoring in Nissan Qashqai?

Nissan Qashqai's tire pressure monitoring display requires a period of normal driving before it appears. Press the menu button on the left side of the steering wheel to switch to the tire pressure page, and it will be displayed on the trip computer. There are three common methods of tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire's air pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data for each tire is displayed. When the tire pressure is too low or there is a leak, the system will automatically alert. Indirect Tire Pressure Monitoring: When the air pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors the tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor air pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of the two systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and a 4-wheel indirect system is also equipped. Compared to using only a direct system, this hybrid system can reduce costs and overcome the defect of indirect systems not being able to detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data on the actual pressure in all four tires like a direct system.

How to Know When Spark Plugs Need Replacement?

Methods to determine if spark plugs need replacement: Remove the spark plugs and observe them. Judge the condition of the spark plugs based on the following appearance colors. Normal spark plugs have a skirt insulator and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a skirt insulator that is reddish-brown, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plug is covered in oil or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, with signs such as blistering at the top, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates the wrong heat range was chosen or the air-fuel mixture is too rich, with oil creeping up. If the spark plug is damaged, it can directly cause issues such as leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most importantly, difficulty in ignition, affecting the normal use of the vehicle. Severe erosion of the spark plug, blistering at the top, damage, or melted and eroded electrodes all indicate that the spark plug is ruined and should be replaced.

Does a Car's Front Wheels Crossing the Line Count as Running a Red Light?

A car's front wheels crossing the line does not count as running a red light. If the front wheels of the vehicle just cross the stop line when the light is red, and the vehicle stops immediately without moving further, it will not be considered as running a red light. According to Article 10 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," continuing to proceed in violation of the rules constitutes running a red light, which results in a 6-point penalty. Article 11 states that if a vehicle completes crossing the line and continues to move until it fully crosses the line before stopping, thereby affecting the passage of other vehicles and pedestrians, it will be penalized for stopping beyond the line, typically resulting in a 2-point deduction on the driver's license and a fine. Article 38 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" specifies the meanings of motor vehicle and non-motor vehicle traffic signals: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of straight-moving vehicles and pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. When the red light is on, vehicles are prohibited from proceeding. When the red light is on, right-turning vehicles may proceed if they do not obstruct the passage of other vehicles and pedestrians. At intersections without non-motor vehicle or pedestrian crossing signals, non-motor vehicles and pedestrians should follow the motor vehicle traffic signals. The new traffic regulations clearly define three necessary conditions for a vehicle to be considered running a red light: The vehicle illegally crosses the stop line. The vehicle illegally enters the intersection. The vehicle illegally crosses the opposite stop line. Electronic police (traffic cameras) capture three complete video images to constitute evidence of running a red light: a snapshot of the vehicle's violation; a vehicle license plate recognition image; and a panoramic image. According to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," there are two scenarios regarding whether a vehicle running a red light is considered a violation: Article 11: If the front wheels of the vehicle cross the stop line, or if both the front and rear wheels cross the stop line but the rear of the vehicle has not yet crossed the stop line, and the vehicle stops immediately, traffic police will not penalize it as running a red light. However, the driver may be penalized for improper stopping, resulting in a 2-point deduction. Article 10: If the front wheels of the vehicle cross the stop line, regardless of whether the entire vehicle has fully crossed the stop line, and the vehicle stops and then reverses back, being captured by traffic cameras with two complete movement images processed as evidence, it will be penalized as running a red light, resulting in a 6-point deduction and a fine.

How Many Reasons Are There for the Engine Fault Light?

There are mainly 7 reasons for the engine fault light to illuminate: Sensor malfunction: The sensors mentioned here include coolant temperature, crankshaft position, air flow, intake temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the car's ECU cannot accurately obtain engine data, which will cause the engine fault light to illuminate. Fuel quality issues: If fuel and engine oil are not added as required by the manufacturer, it may cause engine wear and trigger the fault light. Poor combustion of the air-fuel mixture: Poor combustion can lead to engine carbon deposits or knocking. When detected by the oxygen sensor and reported to the ECU, the fault light will illuminate as a warning. Issues such as faulty spark plugs, ignition coils, fuel pump, or clogged fuel lines can cause poor combustion of the air-fuel mixture. Turbocharging problems: The intake turbocharging pipeline or turbocharger can also cause the engine fault light to illuminate. The most common issue is turbocharger damage, accompanied by symptoms like oil leakage, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake problems: If the car's intake system malfunctions, it may lead to clogged engine pipelines, and in severe cases, the engine fault light will illuminate. A dirty or uncleaned air filter can cause intake issues. Exhaust problems: Exhaust faults can also trigger the engine fault light. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings, with the catalytic converter being the most frequent issue. Using leaded gasoline, lead- or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can easily cause catalytic converter failure. Anti-theft system malfunction: If the car's electronic anti-theft system fails or the anti-theft controller does not match the engine ECU, the anti-theft system can prevent the engine from operating normally and illuminate the fault light. If the engine fault light is on, follow these steps: First, check if the engine is running normally. Look for issues like shaking or black smoke. If present, avoid restarting the engine. Note: Do not restart if the red light is on. If the engine can start, turn it off for 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'ON' position (without depressing the clutch). The car will perform a self-check after powering on. Wait 5-10 seconds to see if the fault light turns off. If the light remains on, visit a service station as soon as possible. Technicians can use a portable diagnostic tool to read fault codes, identify the issue, and perform targeted repairs.
