Does a Rear-End Collision Count as an Accident Vehicle?

To determine whether a rear-end collision qualifies as an accident vehicle, the severity of the impact must be analyzed. Here is relevant information: Accident Vehicle: A vehicle is considered an accident vehicle if there is deformation, twisting, replacement, welding, or wrinkling in components such as the left and right symmetry of the body, left front longitudinal beam, left A-pillar, right front longitudinal beam, left B-pillar, left front shock absorber mounting area, left C-pillar, right front shock absorber mounting area, right A-pillar, left rear shock absorber mounting area, right B-pillar, right rear shock absorber mounting area, right C-pillar, etc. Rear-End Collision: A rear-end collision occurs when the front of a following vehicle impacts the rear of the leading vehicle while both are traveling in the same lane. This is primarily caused by the following distance being less than the minimum safe distance, delayed driver reaction, or poor braking system performance.

How many points are deducted for speed and gear mismatch?

In the Subject 3 driving test, a mismatch between speed and gear results in an immediate deduction of 100 points. Here are the relevant details: Test: During the Subject 3 exam, the gear and speed usage should be as follows: first gear for speeds of 0-15 km/h, second gear for 15-25 km/h, and third gear for 20-35 km/h. As long as the examinee switches between the specified speeds and gears appropriately, ensuring the gear matches the speed, it is acceptable. Light operation: Avoid quickly moving the control lever to prevent the system from failing to detect it. After activating the turn signal, hold it down to prevent it from turning off due to steering wheel movement. The light simulation test has a time limit; being too early or too late can affect the result. Do not fail on the simplest procedures. Speed and gear: Stay calm when shifting gears to avoid incorrect gear selection. Ensure the clutch is fully depressed when shifting; otherwise, gear engagement may be difficult, and nervousness could lead to stalling the engine.

How to Handle ETC for Mortgaged Vehicles?

Mortgaged vehicles can normally apply for ETC without any additional proof, just bring the vehicle registration certificate. Below are the specific details about ETC: 1. Principle of ETC: ETC (Electronic Toll Collection) utilizes microwave-dedicated short-range communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna at the ETC lane of toll stations. It employs computer networking technology to process backend settlements with banks, thereby achieving the purpose of paying tolls without stopping at highway or bridge toll stations. 2. Function of ETC: The ETC non-stop toll collection system is currently the most advanced highway and bridge toll collection method in the world. ETC dedicated lanes are designed for vehicles equipped with ETC onboard units, enabling fast and seamless passage through highway toll stations via electronic payment.

What is the recommended speed indicated by speed limit signs with yellow background and black numbers?

Rectangular signs with yellow background and black numbers indicate recommended driving speeds. Here is relevant information: Speed limit: Speed limits typically refer to the prescribed range of driving speeds for a certain length of road segment, primarily aimed at preemptively reminding drivers to reasonably control their speed in subsequent sections of the road ahead and to prevent the dangers of speeding. Speed limits are an indispensable and most critical aspect of road transportation safety. Zonal speed limits: Based on traffic laws and regulations or enterprise facility regulations, specific zones are delineated in practical situations, and the maximum driving speed for vehicles within these zones is standardized. Common applications of zonal speed limits include school zone speed limits, factory zone speed limits, and speed limits for external vehicles, among others. The ultimate goal of zonal speed limits is to reduce speeding accidents and create a safe and worry-free driving environment for people, vehicles, and objects in areas such as school campuses or factory zones.

Why is the car's reverse light always on?

That's because the reverse switch is constantly activated, possibly due to a malfunction. In this case, you should visit a 4S shop to check for wiring leaks. Reasons why the car's reverse light stays on: 1. Poor performance of the reverse radar itself: This is caused by the reverse radar control unit's own poor performance. 2. Abnormal connection of related wiring. 3. The menu key on the audio system was turned off: The menu key on the audio system was disabled in the central control computer, which includes an option for the reverse radar or parking assist. You can choose to turn it on or off, and it should be set to 'on'.

What Causes the Abnormal Noise in Baojun 510 on Bumpy Roads?

1. Engine Guard Plate: The most common source of abnormal noise is the self-installed engine guard plate, especially those made of iron. Minor underbody scraping often causes the plate to deform, bringing it too close or even in direct contact with the exhaust pipe. Since the exhaust pipe is suspended under the car, it vibrates when accelerating or driving on bumpy roads, leading to collisions and friction with the guard plate, which produces the noise. Therefore, if abnormal noise occurs only when crossing speed bumps, driving on rough roads, or accelerating, and you have installed a guard plate, this should be the first thing to check. 2. Tire Noise While Driving: There are generally two types of noises: a tapping sound and a humming sound. If you hear a tapping sound, carefully listen to identify which wheel is making the noise, or check all wheels if unsure. Possible causes include a large screw puncturing the tire or a big stone stuck in the tread. For a humming sound, it’s not something you can fix yourself—it might be due to uneven tire wear or a damaged wheel bearing, requiring immediate inspection at a repair shop. 3. Steering Wheel Noise: A humming sound when turning the steering wheel to its limit is normal, as it’s the power steering pump releasing pressure under high load. If there’s a squeaky friction noise near the steering wheel, it might be due to the airbag coil rubbing or contact with the plastic trim below the wheel, which can be adjusted.
