What lights to use when turning at an intersection?

Turn on the left turn signal. When a vehicle going straight is about to enter the turning intersection, it should start signaling and then make the turn. The left turn signal should be activated in advance when turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn. The right turn signal should be activated in advance when turning right, changing lanes to the right, returning to the original lane after overtaking, or parking by the roadside. The turn signal can be turned off after completing the turn and driving straight for a short distance. Generally, the turn signal will automatically turn off after the turn is completed. Below is relevant information: Night driving: When driving at night and turning at an intersection controlled by traffic lights, use the low beam. When passing through an intersection without traffic lights, alternately use the high and low beams to signal. No directional signal lights: At intersections without directional signal lights, turning vehicles must yield to vehicles going straight and pedestrians. Right-turning vehicles from the opposite direction must yield to left-turning vehicles.

How many points are deducted for driving in the wrong lane and going against traffic at an intersection?

For the illegal act of driving against traffic, 3 points are deducted for driving against traffic on urban roads, and 12 points are deducted for driving against traffic on highways. There is no penalty of deducting 6 points for driving against traffic. If a driver is deducted 6 points for driving against traffic, it is likely that the driver committed two illegal acts, such as making a U-turn from a side road to the main road and driving against traffic, in which case these two illegal acts result in a deduction of 6 points. Below is relevant information according to the "Road Traffic Safety Law": Article 90: If a motor vehicle driver violates the road traffic safety laws and regulations regarding road traffic rules, a warning or a fine shall be imposed. If this Law provides otherwise, the penalty shall be imposed in accordance with the relevant provisions. Avoid driving in the wrong lane: Slow down before entering an intersection, observe the nearby signs or markings, and clearly understand the direction of each lane at the upcoming intersection in advance. If using a navigation system, pay attention to the navigation instructions when approaching the intersection.

How many kilometers can a scooter motorcycle run continuously?

Motorcycle continuous driving mileage varies depending on the engine type and the vehicle's displacement. Motorcycles with a displacement of more than 150 milliliters and a water-cooled engine can run continuously for about 200 kilometers; for underbone motorcycles with a displacement of about 110 milliliters or cross motorcycles with a displacement of about 125 milliliters, due to heat attenuation issues, it is recommended not to exceed 100 kilometers of continuous driving; due to poor heat dissipation, it is not recommended for scooter motorcycles to run continuously for more than 50 kilometers. The following is relevant information: Motorcycle service life: The service life and continuous running mileage of a motorcycle are closely related to its design. Relevant data show that the service life of a brand-new motorcycle tire is about 50,000 kilometers, while the service life of the engine is about 100,000 kilometers. Safety precautions: During the use of the motorcycle, vehicle maintenance should be done well to minimize high-intensity continuous operation and avoid excessive wear and tear on the vehicle. When driving continuously for a long time, it is also necessary to consider the body's endurance, which is not only responsible for oneself but also for others.

What Happens If the Valve Clearance of a Scooter is Too Large or Too Small?

The intake and exhaust valve clearance of a motorcycle is approximately 0.05 millimeters. When the engine is running, the valves will expand due to the increase in temperature. If there is no gap or the gap is too small between the valve and its transmission components in a cold state, the thermal expansion of the valve and its transmission components in a hot state will inevitably cause the valve to close improperly, resulting in air leakage during the compression and power strokes of the engine. This leads to a decrease in power and, in severe cases, even difficulty in starting. The valve will expand due to the increase in temperature. If there is no gap or the gap is too small between the valve and its transmission components in a cold state, the thermal expansion of the valve and its transmission components in a hot state will inevitably cause the valve to close improperly, resulting in air leakage during the compression and power strokes of the engine. This leads to a decrease in power and, in severe cases, even difficulty in starting. To eliminate this phenomenon, a certain gap is usually left in the valve and its transmission mechanism during cold assembly of the engine to compensate for the expansion of the valve after heating. This gap is called the valve clearance. Here is additional information about the intake and exhaust valve clearance of a motorcycle: The standard for the intake and exhaust valve clearance of a motorcycle is not fixed, as it varies from one motorcycle to another. The size of the intake and exhaust valve clearance may be the same or different. Since the valve train operates at high speed and high temperature, components such as the valve tappet and valve stem will elongate when heated, automatically pushing the valve open. This causes the valve and valve seat to close improperly, resulting in air leakage.

What do C and H on the car dashboard represent?

The C on the car dashboard is the abbreviation of the English word COOL, meaning cold, while H is the abbreviation of HOT, meaning heat. C and H are used to display the car's water temperature, referred to as the water temperature gauge on the dashboard, indicating the temperature of the coolant inside the car engine. The temperature of the car engine's coolant should be maintained within the normal range. The red H on the water temperature gauge indicates that the water temperature is too high, the blue C indicates that the water temperature is too low, and no light on the water temperature gauge means the water temperature is normal. When the car engine is working, fuel combustion generates a large amount of heat. Some of the heat is expelled outside the car through the exhaust pipe, while some remains inside the car's body. Excessive heat can cause the body temperature to rise too high, leading to body expansion and damage. At this time, coolant is needed to maintain the normal temperature of the engine. The hazards of excessively high car water temperature: damage to the vehicle's cooling system fan, damage to the engine thermostat, damage to the engine cylinder gasket; premature deterioration of engine oil, rendering it unable to lubricate. When the vehicle's water temperature is too high, the vehicle needs to be turned off, and the antifreeze usage should be checked. Excessively high water temperature in motor vehicles can cause malfunctions, and in severe cases, render the vehicle unusable. If the driver notices the vehicle's water temperature gradually rising too high during operation, the vehicle must be stopped immediately, and the engine cooling system should be inspected. After identifying the problem, appropriate repairs should be made, and the vehicle can only continue to be driven after ensuring there are no issues. The effects of excessively low car water temperature: increased fuel consumption. Excessively low car water temperature can lead to poor gasoline atomization, incomplete combustion, reduced power, increased fuel consumption, and more carbon deposits. Impact on engine performance: The normal operating temperature of a car engine is generally around 90 degrees. Excessively low water temperature can have a certain impact on engine performance. First, there is the issue of the clearance between moving parts. Low water temperature means less expansion of parts, resulting in excessive clearance and reduced power. The temperature of the engine oil also decreases, increasing its viscosity, which raises the engine's operating resistance and affects power output.

What does the triangle exclamation mark mean in the Volkswagen Lamando?

A triangle with an exclamation mark indicates a malfunction in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. Solution: Visit a 4S shop for inspection to identify the source of the fault. The exclamation mark is a common fault indicator in vehicles. Besides the triangle with an exclamation mark, there are four other forms of exclamation mark warnings: a yellow gear with an exclamation mark, a red circle with parentheses and an exclamation mark in the middle, a yellow parentheses with a horizontal line and an exclamation mark in the middle, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four scenarios: Automatic Transmission Fault: A yellow gear with an exclamation mark indicates an automatic transmission fault warning, signaling a transmission issue or low transmission fluid. The transmission fluid should be replaced promptly. Brake System Fault: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, typically indicating a brake system malfunction or low brake fluid. Immediate inspection of the brake system is required to avoid accidents. Tire Pressure Anomaly: A parentheses with a horizontal line and an exclamation mark in the middle indicates a tire pressure monitoring warning light, which illuminates when tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is a lighting fault indicator, signaling a malfunction in the vehicle's lights. Solution: Visit a 4S shop for inspection as soon as possible, or perform a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.
