Whether a car with a modified exhaust valve can pass the annual inspection depends on the specific circumstances. If the modification does not alter the vehicle's parameters, it can pass the inspection; however, if it changes the vehicle's parameters, it will not pass. Modifications such as altering the intake and exhaust systems, widening the body, lowering the chassis, changing braking components, or blindly upgrading high-beam headlights—all of which change the vehicle's technical parameters—will fail the annual inspection. Vehicle annual inspection is a mandatory test for all vehicles that have obtained official license plates and registration certificates, equivalent to an annual physical examination for the vehicle based on the safety technical conditions for motor vehicle operation. The annual inspection helps to promptly eliminate potential safety hazards, encourages better vehicle maintenance, and reduces the occurrence of traffic accidents.

What Do the Three Turns of the Car Key Represent?

The first turn is the ACC position: powers the radio, CD, DVD, and other electrical devices. The second turn is the ON position: activates the entire vehicle's electrical circuit, allowing all electrical equipment to function at this position. The third turn is the start position: engages the engine without starting the car. The first two positions will consume battery power, differing only in the rate of consumption. Below are some driving precautions: 1. Check the rearview mirrors: Always use turn signals and slow down when turning or changing lanes; check the rearview mirrors before turning. Left turns primarily require checking the left rearview mirror, right turns the right rearview mirror, and both turns require checking the interior rearview mirror. 2. Avoid staring directly ahead: When driving on open roads, focus your gaze about 100 meters ahead rather than fixating on the immediate front of the car. 3. Depress the clutch: Generally, when decelerating above 40 km/h, there's no need to press the clutch immediately; wait until the speed drops to around 20 km/h before depressing it. 4. Steering: Turn the wheel slowly at high speeds and quickly at low speeds.

What Lights to Use When Parking on the Roadside at Night?

When parking on the roadside at night, you should turn on the hazard warning lights. Below are the specific details: Introduction: The vehicle hazard warning lights, often referred to as "hazard lights" or "flashers," are signal lights that alert other vehicles and pedestrians to special circumstances involving your vehicle. Unlike other light switches that are integrated together, the hazard light switch is unique—it exists independently and has a very distinct identifier: a red triangle. Typically, the hazard light switch is located on the center console to the right of the steering wheel, though some models may have it positioned below the center console. When pressed, both sides' warning lights flash simultaneously. Usage of Hazard Lights: On the road, hazard lights are used in foggy conditions. The need for hazard lights in fog depends on the severity of the fog. If the fog is not too thick and visibility does not affect driving at the prescribed speed, then hazard lights are unnecessary. However, in heavy fog with very low visibility, hazard lights must be turned on. On highways, hazard lights should be used in conditions such as fog, rain, snow, dust, or hail when visibility drops below 100 meters.

What is the standard tire pressure for an Audi Q3?

The standard tire pressure for an Audi Q3 is around 2.5, with a fluctuation range of approximately 0.2. The tire pressure tends to be lower in summer and higher in winter. The role of car tire pressure: Tire pressure is an indicator of a vehicle's load capacity. The load capacity of a car depends on the level of tire pressure. According to the relationship between the tire's load index, tire pressure, and load capacity, higher tire pressure results in greater load capacity. Conversely, lower pressure reduces the load capacity. The warning sign for car tire pressure:
