How to Practice Driving Test Part 3 for People with Poor Sense of Direction

Here are specific tips for people with poor sense of direction to practice Driving Test Part 3: 1. Look far ahead and use peripheral references. Keep your gaze as far ahead as possible to better sense any deviation in direction and make adjustments early. Find suitable reference points, using the left side of the car hood as a peripheral reference to gauge its relative position to the road's white lines. Make slight adjustments when the position changes significantly. 2. Keep steering smooth and consistent. During normal driving and lane changes, make small, slow, and gentle steering adjustments, as if gradually aligning the direction. For turns or U-turns, follow two consistencies: 'steer as much as you return, and steer as fast as you return.' 3. Principles for steering. (1) Centering principle: return the steering wheel by the same amount and speed as you turned it, using the car emblem as a reference to check if it's centered; (2) Safety principle: at higher speeds, react quickly to turns with small adjustments, like a finger or half-finger's width; (3) Curve principle: steer proportionally to the curve—quickly for sharp turns (e.g., right-angle turns) and slowly for gentle curves (e.g., S-curves); (4) Remedial principle: if you steer too early, adjust less and slower; if too late, adjust more and faster. Minor oversteering requires small corrections, while understeering requires quick compensation.

Will a flooded new car be replaced with a new one?

No, it cannot be replaced with a new car, but compensation can be provided according to the terms of the auto damage insurance. According to the auto damage insurance clauses, compensation applies to vehicles submerged due to garage flooding or damaged by falling trees or rocks caused by heavy rain. In post-storm damage claims, as long as the engine is not flooded, all repairs and part replacements are covered under the auto damage insurance. Below is an introduction to insurance compensation for flooded new cars: 1. Vehicle submerged while parked: With auto damage insurance, full compensation is provided. If the vehicle is damaged while stationary due to flooding, as long as auto damage insurance is purchased, it falls within the insurance company's compensation scope. This includes vehicles submerged in garages—the resulting damage is covered by auto damage insurance, and the insurance company will provide full compensation. If the vehicle is submerged while stationary, do not move it; instead, report the incident immediately, take photos, and follow the claims process. 2. Vehicle submerged while driving: For car insurance purchased after September 19, 2020, with auto damage insurance, full compensation is provided. Additional coverages like theft insurance, glass insurance, and engine flooding insurance have been merged into auto damage insurance, eliminating the need for separate purchases to qualify for claims. For car insurance purchased before September 19, 2020, with auto damage insurance + flooding insurance, full compensation is provided. If the loss occurs due to unclear judgment of water depth while driving, and the policyholder has auto damage insurance + flooding insurance, the insurance company will provide full compensation; if only auto damage insurance is purchased without flooding insurance, compensation will only cover damages excluding the engine.

What are the symptoms of a damaged exhaust valve?

The symptoms of a damaged exhaust valve are: 1. Difficulty starting, engine shaking, unstable idle, and weak acceleration; 2. When the car burns oil, blue smoke comes out of the exhaust pipe; 3. The engine fault light on the dashboard illuminates. The reasons for exhaust valve damage are: 1. Poor quality of the exhaust valve; 2. Improper maintenance of the exhaust valve; 3. Aging of the exhaust valve; 4. Poor fuel quality. The exhaust valve, also known as the oil-gas separator or pressure control valve, is installed between the compressor outlet and the condenser inlet. It improves heat transfer efficiency in the condenser and evaporator by separating oil and gas. If the exhaust valve is damaged, it needs to be inspected or replaced at a repair shop.

What are the methods for determining reference points in car turning techniques?

When turning, try to avoid borrowing lanes for the turn. Instead, position the vehicle appropriately close to the left edge of the road, maintaining a distance of about 20cm. Below is an introduction to car turning techniques: Reference points for intersection turning techniques: When making a left turn at an intersection, try to choose a wide turn. Wide turns offer a larger field of vision, making it easier to observe surrounding road conditions. Position the vehicle at the starting point of a right-angle turn. Upon hearing the audio prompt, shift into first gear, release the handbrake, slowly lift the clutch while maintaining a semi-engaged state, and begin moving at a steady speed. Keep the vehicle moderately close to the left edge of the road, maintaining a distance of about 20 centimeters. Adjust this distance from the beginning and avoid making corrections when nearing the right-angle turn. Once the distance is set, focus your attention on the right-side door window glass. When the A-pillar aligns with the horizontal line of the inner corner of the right-angle turn, turn the steering wheel fully to the right. Precautions when turning: When turning, try to avoid borrowing lanes for the turn. For example, when turning left, first steer slightly to the right before turning the steering wheel to the left. Of course, if obstacles make this unavoidable, be sure to signal in advance and check if there are any vehicles closely following behind. High-speed turns have always been a leading cause of traffic accidents. Therefore, when turning at high-speed intersections, always stay close to the inner side of the turn, especially for large vehicles. When exiting the turn, drive close to the outer side.

What does the automatic clutch version mean?

Automatic clutch version refers to a car equipped with an automatic clutch transmission. The automatic clutch transmission, also known as the automatic clutch control system, is an intelligent clutch control system developed for manual transmission models. Without altering the original transmission and clutch, it adds an independent system controlled by a microcomputer to engage and disengage the clutch, achieving the effect of driving without stepping on the clutch. Automatic clutch transmissions are divided into: 1. Mechanical motor-type automatic clutch transmission, where the ECU collects signals from the throttle pedal, engine speed sensor, and vehicle speed sensor, processes them, and sends commands to drive the motor, mechanically operating the clutch; 2. Hydraulic automatic clutch transmission, where the ECU sends signals to drive the electro-hydraulic system, hydraulically operating the clutch.
