What is the maximum speed limit on urban roads with center lines?

The maximum speed limit on urban roads with center lines cannot exceed 40 kilometers per hour. The speed of motor vehicles on the road must not exceed the speed indicated by speed limit signs or markings. Other speed limit regulations: Roads without center lines: For roads without center lines, the speed limit is 30 kilometers per hour for urban roads and 40 kilometers per hour for highways. For roads with only one lane in each direction, the speed limit is 50 kilometers per hour for urban roads and 70 kilometers per hour for highways. Urban roads include ordinary city roads and expressways, with the former generally limited to 40-60 kilometers per hour, while expressways may have a maximum speed limit of 80 kilometers per hour. Tunnels and ETC lanes: Tunnels and tunnel groups generally have a speed limit of 80 kilometers per hour. Accident-prone sections usually have a speed limit 20 kilometers per hour lower than the main highway. Sharp curves and interchange ramps are speed-limited according to their design speed. ETC lanes have a speed limit of 20 kilometers per hour, while truck weigh-in-motion lanes have a speed limit of 5 kilometers per hour.

What is a Coupe?

A coupe (Coupe) specifically refers to a two-door, two-seat sedan with a closed body and a streamlined rear. It is generally a sporty variant of a regular sedan, with an appearance very similar to that of a standard sedan. Some coupe models are as follows: BMW 2 Series: The BMW 2 Series is a fully imported two-door coupe with a not particularly high price. This car focuses on design, and its sporty appearance has won the favor of many consumers. The BMW 2 Series also offers relatively ample space. Subaru BRZ: The Subaru BRZ is an affordable sports car and the only Subaru model without four-wheel drive. The BRZ's handling is relatively rational and not prone to losing control, making it suitable for both daily driving and track use. Mazda MX-5: The Mazda MX-5 has fulfilled many people's sports car dreams. A joyful driving experience is the MX-5's biggest feature, and its convertible design is also loved by many. The power delivery is relatively smooth.

What is Considered a Normal Average Fuel Consumption?

The average fuel consumption of motor vehicles is considered normal if it matches the official fuel consumption per 100 kilometers published by the Ministry of Industry and Information Technology, or is 3 to 5 points higher. Tire Impact on Fuel Consumption: The relationship between tires and fuel consumption varies depending on the type of tread pattern. Tires with zigzag patterns are more fuel-efficient compared to standard treads. Fuel-saving tires can reduce fuel consumption. Compared to products of the same specification, fuel-saving tires have lower rolling resistance values under the same load. Reducing rolling resistance leads to lower fuel consumption. If a vehicle is equipped with four fuel-saving tires, it can significantly reduce fuel usage. Drag Coefficient Impact on Fuel Consumption: The design of a car also plays a crucial role in fuel economy, especially at higher speeds, which is referred to as "aerodynamic drag." Reducing air resistance is mainly achieved by minimizing the vehicle's frontal area and drag coefficient. The frontal area depends on the vehicle's size, while the drag coefficient is influenced by the body design. Compact and streamlined car bodies are effective ways to improve fuel efficiency.

When a car is not used for a long time, should the positive or negative terminal of the battery be disconnected?

When a car is not used for a long time, the negative terminal of the battery should be disconnected. Disconnecting the negative terminal cuts off most of the standby power consumption in the vehicle, allowing the battery to discharge naturally. Removing the negative terminal can help the car stay parked for a longer period and better protect the battery. The reason for disconnecting the negative terminal first is that the negative terminal of the car battery is connected to the car body, which is made of metal, meaning the entire body is connected to the negative terminal. If the positive terminal is disconnected first, it may easily lead to electrical conduction. Generally speaking, disconnecting the negative terminal of the car battery will not cause any problems for one to two months. However, long-term parking can still affect the car battery and other components. For example, prolonged parking can cause tire deformation leading to premature tire failure, oxidation and deterioration of engine oil, and paint peeling.

Is 90 points a passing score for C1 Subject 2?

The passing score for the C1 driver's license Subject 2 test is 80 points, so 90 points is a pass. The C1 Subject 2 test mainly consists of five items: reversing into a garage, parallel parking, curve driving, right-angle turning, and stopping and starting on a slope. For automatic transmission (C2) Subject 2, the stopping and starting on a slope is not tested, and in some regions, there is an additional high-speed card retrieval item. The C1 driver's license allows driving small and micro passenger vehicles, among others. Subject 2 test introduction and tips: Before driving during the Subject 2 test, be sure to adjust the seat height and rearview mirrors to ensure a wide field of vision, and fasten your seatbelt. During the test, do not stop unless the voice prompt indicates a failure. Parallel parking: Park the car into the designated space without crossing or touching the lines. Tips: Remember to find the correct angle, turn the steering wheel quickly, react promptly, and coordinate with the car's speed. Slope stopping and starting: Drive slowly up the slope and stop within the designated area. Tips: Remember to engage the handbrake, turn on the left turn signal when starting, release the handbrake, stabilize the clutch, and press the accelerator while releasing the clutch to avoid stalling or rolling back. Right-angle turning: Prepare to turn 90 degrees while driving straight without crossing or touching the lines. Tips: Find the reference point before turning and coordinate with the car's speed. Curve driving (S-curve): Drive slowly through the S-curve without crossing or touching the lines. Tips: Control the speed, slow down, and coordinate the timing of turning the front of the car. Reversing into a garage: Reverse the car into the garage without stalling or crossing/touching the lines. Tips: Control the speed, find the reference point, and make minor adjustments when observing deviations in the rearview mirror. C1 driver's license test passing standards: Traffic laws and related knowledge—90 points to pass. Field driving—80 points to pass. Road driving—80 points to pass. Safe and civilized driving knowledge—90 points to pass. Subject 2 deduction items: Reversing into a garage: Vehicle body crossing the line—deduct 100 points, failing the test; failing to reverse into the garage—deduct 100 points, failing the test; stopping midway—deduct 5 points each time; failing to complete the test within the specified time—deduct 100 points, failing the test. Parallel parking: Vehicle body crossing the line after parking—deduct 100 points, failing the test; stopping midway—deduct 5 points each time; tires or body touching the curb while driving—deduct 10 points; failing to complete the test within the specified time—deduct 100 points, failing the test. Curve driving: Wheels crossing the road edge line—failing the test; stopping midway—failing the test; driving gear not in second or above—deduct 5 points. Right-angle turning: Wheels crossing the road edge line—failing the test; stopping midway—deduct 5 points each time. Slope stopping and starting: After stopping, the front bumper of the car or the front axle of the motorcycle is not aligned with the pole line and exceeds 50 cm—failing the test. Starting time exceeding the specified time—failing the test. After stopping, the front bumper of the car or the front axle of the motorcycle is not aligned with the pole line but does not exceed 50 cm—deduct 10 points. After stopping, the distance between the vehicle body and the road edge line exceeds 30 cm but not 50 cm—deduct 10 points. Failing to engage the parking brake after stopping—deduct 10 points.

What is the function of automatic steering correction?

Steering wheel automatic return is a function where the steering wheel automatically returns to the center after turning, whether the steering is fully turned or partially turned. In normal vehicles, the steering wheel will automatically return to the center when released. Steering wheel automatic return is a basic function of a car, and its main role is to enhance the driving control feel of the vehicle, as well as being an important indicator of the car's handling performance. Additional information: 1. Steering wheel return during turns: The steering wheel can return to the center during turns because the tires tend to move in the direction of least resistance when the car continues to move forward, which is the straight direction. When the vehicle is moving, the steering resistance is higher than the straight-line resistance, so the steering naturally avoids high resistance and automatically returns to the center without external force. 2. Front wheel return: Viewed from the side of the car, the kingpin axis and the ground do not form a right angle but are slightly tilted backward, creating an angle known as the caster angle. This causes the intersection point of the kingpin axis and the ground to create a distance from the wheel. During steering, the lateral force from the ground on the wheel generates a torque on the kingpin, which helps the front wheels return to the center.
