Modifying a car spoiler is not legally compliant. Currently, the "Motor Vehicle Inspection Work Regulations" have relaxed some restrictions on car modifications, but policies do not support spoiler modifications. Altering a car spoiler is considered a change to the vehicle's exterior appearance and is classified as a violation, hence it is not recommended. Below is more information about car spoilers: 1. Car spoilers are part of aerodynamic design. Generally, factory-installed spoilers on civilian vehicles are not overly exaggerated, and some even feature retractable spoilers. 2. When a car is traveling at high speeds, air passing over the spoiler can increase the vehicle's downforce (typically adding several dozen kilograms, with some even exceeding 100 kilograms), enhancing driving stability. 3. A well-designed spoiler can reduce air resistance, contributing to fuel efficiency to some extent.

How many days does it take to check the traffic violation record on October 1st?

It takes 7-10 days to check the traffic violation record on October 1st. Methods for determining traffic violations: Traffic violations are determined through electronic monitoring. Behaviors captured by electronic surveillance require manual review, which typically takes about 72 hours to upload the record. After that, it will be synchronized to the Traffic Management 12123 platform, and it takes 3-7 working days to query the violation record. Non-on-site violations: Non-on-site violations (violations captured by cameras) take about 15 days to be checked. The time varies in different regions. Therefore, if car owners are worried about potential violations, they can check online for relevant information about a week after they suspect a violation.

Do I need to keep pressing the brake when in N gear?

You don't need to keep pressing the brake when in N gear. N gear is neutral gear: In this gear, the transmission is also in a no-load state, but the vehicle can move. Unlike P gear, the transmission is not locked. Therefore, if you want to use the air conditioning while in N gear, you must engage the parking brake (handbrake) to prevent the vehicle from rolling. Definition of car braking: Braking, also known as stopping, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transport tools, or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install a corresponding brake shoe, band, or disc on the machine base, which generates braking torque under external force.

Why is the car air conditioner not heating?

If the car air conditioner is not heating, common causes include insufficient antifreeze. It is advisable to promptly replenish the coolant or check if the heater core is clogged. Introduction to Car Air Conditioning: The car air conditioning device (air-conditioning-device), commonly referred to as car air conditioning. Functions of Car Air Conditioning: It is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to an optimal state, providing a comfortable riding environment for passengers and reducing travel fatigue; it also creates favorable working conditions for the driver, serving as an important ventilation device for ensuring safe driving.

What Causes the Red Oil Light to Illuminate?

Reasons for the red oil light illuminating: insufficient oil level, faulty pressure sensor, or oil pump malfunction. Insufficient oil level: The oil pump's output decreases, leading to a drop in oil pressure and the illumination of the oil pressure light. In this case, it is necessary to check if there are any leaks in the engine or if there is a fault causing oil consumption. Faulty pressure sensor: The oil pressure sensor itself may be faulty, causing the vehicle's computer to receive incorrect oil pressure data, thus triggering the oil pressure light. Alternatively, the wiring harness of the oil pressure sensor may have a fault, such as an open circuit or short circuit, leading to the illumination of the oil pressure light. Oil pump malfunction: The oil pump may be internally worn, causing the oil pump itself to malfunction and resulting in the illumination of the oil pressure light.

What are the speed limits for two lanes?

If it is a highway with two lanes in the same direction, the speed limit for the left lane is 100 to 120 kilometers per hour, and the speed limit for the right lane is 60 to 80 kilometers per hour. If it is an urban road, the speed limit for both lanes is 30 to 40 kilometers per hour. Introduction to speed limits: Speed limits generally refer to the regulation of vehicle speeds within a certain numerical range over a specified distance of road. Purpose of speed limits: The main purpose is to preemptively remind drivers to reasonably control their speed in subsequent sections of the road ahead, prevent the dangers of speeding, and ensure driving safety. Speed limits are an indispensable and most important part of road transportation safety.
