How long do I have to wait to retake the test if I fail Subject 2?

You need to wait at least 10 days to retake the test if you fail Subject 2. Here are some important notes for the Subject 2 test: 1. Seatbelt: Fasten your seatbelt as soon as you get in the car. Make sure not to buckle it incorrectly or buckle it to the passenger seat, otherwise the system will directly judge the test as failed. Do not unfasten the seatbelt during the entire test. 2. Adjustments: After getting in the car, adjust the seat, adjust the rearview mirror, fasten the seatbelt, turn on the left turn signal, shift to first gear, and release the handbrake. These six steps are essential. Make sure all preparations are complete before starting. 3. Reverse parking: There is no time limit for reverse parking, but it is important to note that you cannot stop during the process. If the wheels remain stationary for 3 seconds, the system will judge it as stopping midway. Therefore, controlling the speed is crucial.

How to distinguish between a hump bridge and bridge bump?

The sign for a hump bridge is a raised arched bridge, used to alert drivers to drive cautiously. It is placed at an appropriate position before a hump bridge with significant curvature that affects sight distance. On the other hand, bridge bump is a sign of uneven road surface, featuring two raised sections rather than an arched bridge. The causes of bridge bump are introduced as follows: 1. Cause 1: The main factors causing bridge bump include uneven settlement, abrupt changes in stiffness, vehicle speed, and the vehicle's own vibration resistance performance. 2. Cause 2: In terms of urban road conditions, it is primarily due to uneven settlement at the junction between flexible roads and rigid structures, resulting in step formation. 3. Cause 3: There are differences in the composition materials, stiffness, strength, and thermal expansion properties between bridges and roadbeds or pavements. Additionally, concentrated stress easily forms at bridge connections when subjected to force.

Will there be any consequences if I scratched someone else's car a little and drove away?

If the offending vehicle can be identified, the driver will be detained. Accidentally scratching someone else's car while driving is considered a minor traffic accident. The other party's losses will be fully compensated by the insurance company. If not reported to the insurance company, the individual will bear the cost, which is usually not substantial. Below is relevant information about scratch repair: 1. Minor scratches: Minor scratches on the vehicle can be repaired using a scratch repair agent. The repair agent can prevent the paint from oxidizing and rusting. 2. Moderate scratches: Moderate scratches can be repaired using a touch-up pen. During the repair process, ensure the color matches the vehicle's body color. Clean the scratched area before applying the primer. Once the primer is dry, smooth it with water sandpaper, and finally apply the touch-up pen for coloring. 3. Severe scratches: If the vehicle's scratches are very severe, completely exposing the primer and damaging the steel plate, it is recommended to go to a professional repair shop for paint repair.

Can stones in brake pads come out on their own?

Stones in brake pads can come out on their own. It is normal for small stones to get between the brake pads and brake discs of a car, and most stones will come out by themselves. If a stone gets stuck in the brake disc, you can first accelerate, then brake hard, and then reverse and brake hard again. Repeating this cycle a few times should solve the problem. If this method doesn't work, you will need to take the car to a repair shop or a 4S store for professional handling. Under normal driving conditions, the lifespan of front brake pads is typically 30,000 to 50,000 kilometers, while rear brake pads can last 120,000 to 150,000 kilometers. The exact replacement time depends on the wear condition. Different vehicle models may have varying manufacturer-recommended mileage intervals. When replacing brake pads, it is advisable to choose products from reputable manufacturers. Genuine brake pads usually have clear packaging with details such as the license number, specified friction coefficient, and execution standards. The packaging should also include a certificate of compliance, production batch number, and production date. It is recommended to have new brake pads installed by professionals at a certified repair shop to avoid mistakes that could lead to potential safety hazards.

6 Methods to Handle Angles in Reverse Parking

6 Methods to Handle Angles in Reverse Parking. 1 Steering too early, 2 Steering too late. Below are the details: 1. Steering too early: When turning the steering wheel fully to reverse, observe the distance between the right side of the car body and the parking spot corner through the right rearview mirror. You can adjust this distance by turning the steering wheel back. If the distance is too close, quickly straighten the steering wheel. After straightening, continue observing the corner position through the rearview mirror to ensure the rear wheels can enter the parking spot, then turn the steering wheel fully again. After turning fully, keep observing the parallel relationship between the car body and the parking spot lines through the left and right rearview mirrors. When they are almost parallel, straighten the steering wheel and stop by pressing the brake and clutch when the lower edge of the left rearview mirror aligns with the parking spot entrance line. 2. Steering too late: Similarly, when turning the steering wheel fully to reverse, if the car body is parallel to the parking spot lines, keep the steering wheel fully turned without straightening. Let the car body enter the parking spot at an angle to create distance from the nearby line, paying attention to the timing of straightening the steering wheel. Once sufficient distance is created, straighten the steering wheel to align the car body, then slowly reverse until reaching the stopping point.

What Causes the Jerking Sensation When Releasing the Accelerator in a Car?

There are several reasons why a car may jerk when releasing the accelerator, including transmission abnormalities, fuel supply issues, and a faulty clutch switch. The details are as follows: Transmission abnormalities: Persistent dirt and impurities inside the transmission can prevent effective regulation of oil pressure, leading to jerking, impact, or slippage. The solution is to first check the transmission fluid to see if it is low or has deteriorated. Fuel supply issues: Carbon buildup or minor blockages in the fuel injectors can cause inconsistent fuel delivery among the four injectors, leading to irregular fuel supply and resulting in a jerking sensation. The solution is to inspect the fuel injectors for blockages and clean them promptly. Faulty clutch switch: The clutch switch, located beneath the clutch pedal, works with the ECU to improve gear-shifting quality. For example, during upshifts, the ECU can moderately adjust the throttle and ignition to ensure smoother power transitions and seamless gear changes. When releasing the accelerator while driving, the engine does not immediately reduce fuel injection but does so gradually, allowing the engine speed to decrease smoothly and avoiding excessive engine braking, which can cause jerking. If the clutch switch malfunctions, these control functions fail, making jerking more likely to occur.
