What is the maximum speed limit in tunnels?

Tunnel speed is limited to a maximum of 40 kilometers per hour. During severe weather conditions and in special sections such as bridges and tunnels, the speed limit is subject to the on-site speed limit signs. Speed calculation formula: The calculation method for speed is V=S/t, which represents the distance traveled per unit of time. The speedometer uses data monitored by sensors, calculating the actual speed of the vehicle based on the number of wheel rotations, diameter, and time. Precautions for driving into tunnels: Reduce speed and turn on lights before entering the tunnel, avoid using high beams, strictly adhere to speed limits, do not honk inside the tunnel, do not exit the vehicle for repairs, maintain a safe distance, do not change lanes, accelerate promptly after exiting the tunnel, place warning signs quickly if the vehicle breaks down in the tunnel, and evacuate all passengers.

How Long After Car Paint Repair Can It Be Exposed to Rain?

It is recommended to wait at least 24 hours after car paint repair before exposing the vehicle to rain or washing it. If the paint has been baked, it can be exposed to rain or washed after 2 hours. Reasons why freshly painted cars should avoid rain: Newly applied paint is still soft, and exposure to rain can affect its smoothness. Additionally, rain before the paint fully cures may compromise the protective film formed after curing, potentially leading to paint cracking in severe cases. Solutions if rain occurs after painting: If the paint was applied at a 4S dealership, there's usually minimal impact, though the paint's glossiness might be slightly reduced. Regular maintenance and waxing can restore its shine. For vehicles painted at general repair shops or without baking, wait about a week for the paint to fully cure before inspection. If water marks appear, use 1500-grit sandpaper with a sanding block and water to polish them out, followed by washing and polishing. This method typically removes water marks; if unsuccessful, repainting may be necessary.

What is the average fuel consumption of a sedan?

Generally, the fuel consumption for a sedan with a 1.0-liter engine is around 5 liters per 100 kilometers, while a 1.5-1.6-liter engine consumes approximately 7 liters per 100 kilometers. Starting slowly can save fuel: Many drivers tend to accelerate aggressively when starting, which significantly increases fuel consumption. Therefore, it is advisable to start the car gently to save fuel and create a smoother driving environment. Maintaining a steady speed can save fuel: Most vehicles achieve lower fuel consumption at speeds between 60-90 km/h, known as the economical speed range. Keeping the vehicle within this speed range when possible can save fuel. Fuel consumption increases when driving too fast or too slow. Driving too slowly prevents complete fuel combustion, while driving too fast increases air resistance, leading to higher fuel consumption. Light acceleration can save fuel: Accelerate gradually and avoid flooring the accelerator, as this wastes fuel and causes additional wear on the engine.

Can Enlarged Rims Be Registered Through Unauthorized Agents?

Enlarged rims cannot be registered through unauthorized agents, as the management of motor vehicles is handled by the traffic management departments of public security authorities, not by unauthorized agents. There are no benefits to changing rim sizes: In fact, while increasing rim size may make the car slightly more eye-catching, it poses safety hazards. Choosing larger rims without altering the wheel diameter inevitably requires thinner tires, which are prone to bulging and result in higher maintenance costs later on. Additionally, thinner tires, although they may improve vehicle handling, can negatively impact ride comfort. Scope of illegal vehicle modifications: Any changes to the color, model, performance, purpose, or structure of a licensed motor vehicle, including replacing the chassis, body, or engine, must be reported to the vehicle management office for modification registration. Modifications such as changing rims, adding wide body kits, or altering exhaust systems are generally not permitted.

Can You Still Drive When the Engine Emission Control System is Detected?

Can You Still Drive When the Engine Emission Control System is Detected? Causes of Exhaust System Failure: The illumination of the engine exhaust system fault light is mostly caused by damage to the oxygen sensor in the three-way catalytic system or poisoning of the three-way catalytic converter due to poor fuel quality in the domestic market. If this light comes on while driving, immediately reduce speed and proceed to the nearest service station for inspection and repair. Methods to Determine Exhaust Gas Quality: The exhaust emission control system indicator light will illuminate when the ignition switch is turned on and must go off after the engine is started. If the indicator light does not go off after starting the engine or comes on or flashes while driving, it indicates that there may be unstable operation in the emission control system and the exhaust gas quality exceeds the standard.

How many points are deducted for stopping during Subject 2 of the driving test?

Stopping during Subject 2 of the driving test results in a deduction of 5 points. The evaluation criteria define stopping as when the vehicle pauses for 2 seconds or more. Techniques to avoid stopping midway are as follows: Drive slightly faster: When encountering road boundaries or uneven surfaces, maintain a slightly higher speed. Ease off the clutch: When performing maneuvers that require full steering lock, release the clutch slightly to prevent the vehicle from stalling due to insufficient power. Coordinate clutch and brake: At slower speeds, ease off the clutch more or avoid pressing the brake too hard. If necessary, apply a bit of throttle. As long as you don't stop within the designated test area, it won't be considered stopping midway.
