Before changing lanes at an intersection, drivers should enter the desired lane within the dashed line area following the guidance arrows. Below is an introduction to intersections: 1. Introduction: An intersection refers to a level crossing, where two or more roads intersect on the same plane. 2. Generalization: The term 'roads' here refers to all types of roads as defined in the supplementary provisions of the Road Traffic Safety Law, including urban roads, alleys, lanes, and highways. However, the intersection of alleys or lanes with pedestrian sidewalks along urban streets is not considered an intersection. 3. Regulations: Level crossings between highways and rural paths not classified as highways are also not considered intersections; similarly, level crossings between railways and roads are not regulated as intersections here. For motor vehicle passage at railway crossings, the Road Traffic Safety Law and its Implementation Regulations have specific provisions.

As a novice driver, I always prefer to plan ahead when changing lanes at intersections to avoid making maneuvers inside the junction and prevent accidents. About a hundred meters before reaching the intersection, I glance at the navigation or roadside signs to decide on the target lane. Then, I quickly turn on the indicator to give trailing vehicles ample warning. Checking blind spots is a must—there might be vehicles or pedestrians hidden in dead zones. Once safety is confirmed, I smoothly merge into the lane, never rushing when the light turns green. This habit has saved me a lot of trouble at urban intersections; especially when traffic lights change quickly, it’s crucial to patiently wait for a gap to proceed, avoiding getting stuck at a red light and wasting time. Practicing these steps more often makes driving safer and boosts confidence. I recommend new drivers start practicing at simple intersections to develop the good habit of early lane changes.

Having driven for over a decade, I always complete lane changes at intersections well in advance, never making last-second maneuvers. I plan my lane selection hundreds of meters ahead, aligning with turn indicators or destination directions. Remember to use turn signals for at least three seconds, giving others time to react. After checking mirrors, always do a shoulder check for blind spots—experience says never rely solely on electronic alerts; visual confirmation is most accurate. Complete lane changes before entering intersections to avoid traffic snarls or sudden signal changes. Speed control is crucial: maintain smooth driving, avoiding abrupt acceleration or braking. In urban driving, I account for hidden hazards like cyclists and pedestrians, yielding early for safer passage. This method saves hassle and time, ensuring smoother journeys.

The principles of safe driving teach me that changing lanes at intersections must be completed before entering. Start early, use turn signals clearly, and check blind spots to ensure zero blind spot threats. Avoid actions within the intersection to reduce accident risks. Obeying traffic signals is key; never change positions under a red light to affect passage. This habit can improve efficiency at urban intersections and help prevent rear-end collisions. Ensure smooth lane changes with buffer distances for more stable and reliable driving.

What are the reasons why vehicles are prone to skidding in tunnels?

It may be due to environmental factors that make tunnel surfaces prone to moisture and slipperiness; vehicle exhaust and oil deposits on the road surface form a layer of oil film. Here are some precautions to avoid vehicle skidding: Avoid sudden acceleration: When starting the car, do not accelerate too abruptly. Always apply the throttle moderately and slowly to prevent sudden forward movement, which can easily cause the car to skid if the steering wheel is not properly controlled. Avoid sudden braking: When stopping or slowing down, do not slam on the brakes. Instead, use a pumping motion by pressing and releasing the brake pedal gradually to bring the car to a slow stop. Maintain a steady speed: While driving, maintain a constant speed. If an emergency requires acceleration, do so gradually to prevent sudden acceleration, which can cause the car to skid sideways.

What are the causes of abnormal noise in diesel engines?

Diesel engine fuel injection pump connecting steel plate is damaged. The following is a relevant introduction about diesel engines: 1. Concept: A diesel engine is an engine that burns diesel fuel to obtain energy release. The advantages of diesel engines are high power and good economic performance. The working process of a diesel engine has many similarities with that of a gasoline engine, with each working cycle also going through four strokes: intake, compression, power, and exhaust. 2. Development prospects: Being bulky, noisy, and emitting black smoke has given many people a poor first impression of diesel engines. After years of research and the application of new technologies, the current state of modern diesel engines is incomparable to the past. Modern diesel engines generally use technologies such as electronic control injection, common rail, and turbocharged intercooling, achieving significant breakthroughs in weight, noise, and smoke levels, reaching the standards of gasoline engines.

What is the reason for slippery conditions in tunnels during Subject 4?

The reason vehicles tend to skid inside tunnels is due to slippery road surfaces. Since tunnels are not exposed to sunlight, they remain relatively dark, and combined with water dripping from the mountain walls, the ground becomes slippery. The Subject 4 exam consists of 50 questions, presented in the form of case studies, images, animations, etc., with a total score of 100 points, and a passing score of 90. Subject 4, also known as the Subject 4 theory test or driver's theory test, is part of the motor vehicle driver's license assessment. After the implementation of the Ministry of Public Security's Order No. 123, the Subject 3 test was divided into two parts: the road test and an additional safety and civics knowledge test, commonly referred to as "Subject 4," which evaluates "driving ethics." Because this test is conducted after Subject 3, it is colloquially called the Subject 4 exam. Officially, however, there is no "Subject 4." Failing Subject 4 does not require retaking previously passed subjects (Subject 1, Subject 2, Subject 3). Candidates can schedule a retake on their own, and no additional fees are required for the retake. There are no restrictions on the number of retakes, but the validity period of the driving skills test permit is three years. If the applicant does not complete the exam within this period, the results of any passed subjects will be invalidated.

Is the Volkswagen brake vacuum pump clip easy to remove?

Volkswagen brake vacuum pump clips are not easy to remove and require removal at a 4S shop. The following are specific symptoms of brake vacuum pump failure: 1. Brake feels too hard: When stepping on the brake, if the braking sensation is noticeably too hard, and each pedal stroke is very small, or even pushes the foot back, it is likely due to air leakage in the brake vacuum pump, causing the vacuum pump's assist function to fail. 2. Abnormal noise from the vacuum pump: Poor-quality vacuum pumps may produce noticeable abnormal noises, but this does not affect the car's braking performance. 3. Brake pedal does not return or returns slowly: If after stepping on the brake pedal, the pedal neither rises nor offers resistance, this is a sign of the brake not returning. It is necessary to check whether the brake vacuum pump, master cylinder, or sub-cylinder components are damaged.

What is the function of TCS in a car?

TCS stands for Traction Control System, also known as the Anti-Slip Regulation system. When a car is driving on slippery surfaces, a car without TCS is prone to wheel spin during acceleration, and if it's the rear wheels, it can cause the car to fishtail. Here is more related information: The role of TCS in a car: The traction control of a car can be achieved by reducing the throttle opening to decrease engine power or by controlling the brakes and preventing wheel spin. Cars equipped with ASR (Anti-Slip Regulation) use a combination of these two methods, known as ABS/ASR. The functions of TCS in a car: Its first function is to improve traction; the second is to maintain driving stability. During turns, if the drive wheels spin, it can cause the entire vehicle to drift to one side. With ASR, the vehicle will steer along the correct path. In cars equipped with ASR, the mechanical connection between the accelerator pedal and the throttle (or diesel injection pump lever) is replaced by an electronic throttle control system. Compared to other traction control systems, ESP (Electronic Stability Program) not only controls the drive wheels but also the non-drive wheels. For example, in rear-wheel-drive cars that often experience oversteer, where the rear wheels lose control and fishtail, ESP will brake the outer front wheel to stabilize the car. In cases of understeer, to correct the tracking direction, ESP will brake the inner rear wheel to adjust the driving direction.

Why Does the Car Make Abnormal Noises When the Speed Exceeds 120?

Check whether the front wheel alignment angles and toe-in meet the requirements. Here are some relevant introductions about vehicle driving: 1. Precautions: Strictly prevent speeding. Normally, when the speed reaches 72 kilometers per hour, the vision of a driver with normal eyesight of 5.1 will drop to 4.8, significantly reducing the driver's ability to discern the surrounding environment and pedestrians. Speeding disrupts the vehicle's performance indices under specific conditions, increases the vehicle's working intensity and load, and accelerates the wear and damage of mechanical parts. 2. Skills: To cope with the rapidly changing traffic conditions on the road, it is necessary to make quick judgments within 0.75 seconds and take appropriate technical measures to ensure traffic safety. When driving without alcohol consumption, the reaction time from visual perception to stepping on the brake pedal upon detecting a dangerous situation ahead is 0.75 seconds.
