Techniques for Curve Driving Points in Subject 2

There are many techniques for curve driving, and the following is a detailed introduction: 1. Pay attention to the position of the front of the car: When entering the S-curve entrance, pay attention to the position of the front of the car and try to drive in the middle of the road. When the car is about to enter, make sure the speed is not too fast; it's best to maintain a constant speed and advance in 1st gear with semi-linked clutch. When entering the curve, try to drive close to the right side of the curve, as the first turn is to the left, and remember to observe the left and right rearview mirrors. 2. Steering: When the left corner of the car coincides with the right sideline, immediately turn left one full circle, and during driving, always observe the left corner of the car pressing against the sideline to ensure the car does not cross or go out of the line. 3. Straighten the steering wheel: When the left corner of the car touches the left line of the second curve, straighten the steering wheel and then slowly move forward for a while.

What does 'sweeping the line' mean in Subject 2?

Sweeping the line refers to the vehicle body crossing the line. In the Subject 2 driving test, if the vehicle body crosses the line, 100 points will be deducted, resulting in a failed test. In addition to the vehicle body crossing the line, other actions that will deduct 100 points include failing to park properly in reverse, stopping midway, not following the prescribed route or sequence, and exceeding the allotted time. The Subject 2 test is scored out of 100 points, with criteria for failing, deducting 20 points, 10 points, or 5 points. The test is considered passed under the following conditions: ① For applicants of large buses, tractors, city buses, medium buses, or large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. If a candidate fails the Subject 2 test, they are allowed one retake on the spot. If they choose not to retake or fail the retake, the test is terminated, and the applicant must reschedule the test after ten days. Within the validity period of the driving test permit, candidates can schedule the Subject 2 and Subject 3 road tests no more than five times. If the fifth attempt is still unsuccessful, any previously passed subjects will be invalidated.

Will the Exam Fee Be Refunded If I Cancel the Subject 2 Test?

As long as the appointment is successfully made and the payment is completed, the exam fee will be refunded upon cancellation. Canceling the Subject 2 test during the processing stage generally has little impact, as 'processing' means the appointment has not yet been successfully confirmed, which falls within the normal scope of test cancellation. According to the 'Regulations on the Application and Use of Motor Vehicle Driving Licenses,' test appointments can be canceled a maximum of three times. Exceeding this limit will require cancellation in person at the vehicle management office, as online cancellation will no longer be available. If the appointment has already been successfully made, canceling the test will affect your ranking. When rescheduling the test, your appointment ranking will be placed behind candidates who did not secure a spot in the previous exam. If the number of local candidates is high, this will increase the difficulty of successfully securing an appointment. Subject 2, also known as the small road test, is part of the motor vehicle driving license assessment. It refers to the field driving skills test. For small vehicles (C1 and C2), the test items include five mandatory components: reverse parking, parallel parking, hill start, right-angle turn, and curve driving (commonly known as the S-turn). Some regions may include a sixth item: high-speed toll card collection.

Why is the ABS light always on?

When the car displays ABS, it means there is a malfunction in the vehicle's Anti-lock Braking System. During emergency braking, if the wheels lock up, the vehicle may lose control and skid, making it impossible for the driver to slow down or adjust the vehicle's trajectory, posing significant safety risks. There are several states in which the ABS light may illuminate, with different causes and solutions for each state, as detailed below: State 1: ABS warning light stays on continuously (most common). Cause 1: The ABS wheel speed sensor's sensing part is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle speed and the wheel's slip rate, thus failing to issue appropriate commands to adjust braking. Solution: Clean the dirt from the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal due to loose connections between system lines or poor contact in the ABS relay, leading to system failure. Solution: Check the connection points of the lines and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off when accelerating. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. As the engine speed increases, the voltage rises, and the ABS indicator light turns off. The ABS system's power supply voltage is too low, possibly due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; poor contact in the ABS hydraulic valve body's electrical connector; ABS computer malfunction. Solution: Loosen the grounding screw of the hydraulic valve body, then retighten it, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR computer. State 4: ABS warning light illuminates during high-speed driving. Cause: During high-speed driving, the ABS computer detects a significant discrepancy between the rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: Start the engine, press the brake pedal, push the brake switch linkage down fully with a finger, then release the brake pedal to complete the self-setting position; replace the brake light switch if necessary.

Do You Need to Use Turn Signals During Curve Driving in Subject 2?

During curve driving in Subject 2, it is not necessary to use turn signals. There are a total of 6 situations in Subject 2 where turn signals are required, which are: When starting the vehicle, turn on the left turn signal; When starting on a slope, turn on the left turn signal; During parallel parking, turn on the right turn signal when the vehicle passes the parking spot and stops 30 cm away from the curb, preparing to reverse; Before shifting into reverse gear during parallel parking, turn on the left turn signal because the steering wheel will be turned fully to the right during reversing, causing the front of the car to shift left; Before exiting the parking spot during parallel parking, shift into drive gear and turn on the left turn signal, then turn it off promptly after exiting; When entering the right-angle turn area, turn on the left turn signal and turn it off promptly after completing the turn. Penalties for incorrect use of turn signals are as follows: Failing to use or incorrectly using turn signals before starting, turning, changing lanes, overtaking, or parking will result in a 10-point deduction. Turning the steering wheel within 3 seconds of activating the turn signal before starting, turning, changing lanes, overtaking, or parking will result in a 10-point deduction. The full score for Subject 2 is 100 points, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed under the following conditions: ① For applicants of large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. The test items for small vehicles C1 and C2 include reversing into a parking space, parallel parking, slope parking and starting (canceled for C2), right-angle turns, and curve driving (commonly known as S-curves) as mandatory items (some regions also include a sixth item: highway toll card collection). The test items for large vehicles A1, A2, A3, B1, and B2 include pole test, slope parking and starting, parallel parking, single-plank bridge crossing, curve driving, right-angle turns, narrow gate crossing, continuous obstacle crossing, bumpy road driving, narrow road U-turns, as well as simulated highway driving, continuous sharp mountain road turns, tunnels, rainy (foggy) conditions, slippery roads, and emergency handling.

Is the Exhaust Tip Covered Under Warranty?

Exhaust Tip Covered Under Warranty. Introduction to Exhaust System: The automotive exhaust system primarily discharges waste gases produced by engine operation while reducing pollution and noise levels from the emitted exhaust. Vehicle exhaust systems are mainly used in light-duty vehicles, compact cars, buses, motorcycles, and other motor vehicles. Emission Reduction Methods: To reduce noise at its source, it is essential to first understand the mechanisms and patterns of noise generation. This can be achieved by improving machine design, adopting advanced manufacturing processes, minimizing excitation forces that cause noise, reducing the response of noise-producing components to these forces, and enhancing machining and assembly precision.
