Will the installation of an anti-lock braking system significantly reduce braking distance?

Installing an anti-lock braking system (ABS) can reduce braking distance. During vehicle braking, the system automatically controls the braking force to prevent wheel lock-up, maintaining a state of rolling and sliding (with a slip ratio around 20%), ensuring maximum adhesion between the wheels and the road surface. However, ABS systems have their limitations. In two scenarios, ABS may not provide the shortest braking distance: one is on smooth, dry roads when braking is performed by an experienced driver, and the other is on loose gravel, soft soil, or deep snow-covered surfaces. The anti-lock braking system enhances safety during emergency braking. Without ABS, emergency braking can easily lead to wheel lock-up, rendering the steering wheel unresponsive, thereby increasing the risk of severe consequences. Single-channel ABS typically controls both rear wheels based on the low-select principle. This type of ABS may not fully utilize the adhesion of both rear wheels, so the braking distance might not be noticeably reduced. Additionally, since the front wheels' braking is not controlled, they may still lock up during braking, leaving steering capability unimproved. However, single-channel ABS significantly enhances directional stability during braking by preventing lock-up of the rear wheels.

What is the probability of being photographed for crossing solid lines to change lanes at traffic light intersections?

There is no definitive probability, and drivers are expected to consciously comply with traffic rules. The following situations are not considered violations: Detouring to avoid emergencies: If an accident or natural disaster affects the road ahead, making it impassable for an extended period and forcing vehicles behind to cross solid lines to detour, this will not be treated as a traffic violation. Following traffic police instructions: According to the Road Traffic Safety Law, when traffic signals malfunction and a traffic officer is directing traffic on-site, drivers must follow the officer's instructions. Yielding to emergency vehicles: If running a red light or crossing solid lines occurs while giving way to emergency vehicles such as fire trucks or ambulances, it will not be considered a violation. If penalized due to being captured by traffic cameras, the penalty can be revoked through administrative reconsideration.

Is Braking Prohibited in Subject 2?

In the Subject 2 driving test, there are certain situations where braking is required, such as during the hill start and stop at a designated point, parallel parking, and stopping when reversing into a parking space. However, apart from these specific maneuvers, stopping midway is not allowed in other parts of the test, meaning the speed cannot drop to zero. Below is relevant information about Subject 2: Learning Objectives: Master the basic driving operation essentials and possess fundamental vehicle control capabilities; proficiently grasp basic methods for driving in confined spaces and on internal roads, with the ability to reasonably use vehicle controls and correctly manage the vehicle's spatial position, accurately controlling the vehicle's position, speed, and route. Test Scope: The C1 and C2 license tests include five mandatory items: reversing into a parking space, parallel parking, stopping and starting on a slope, turning at a right angle, and driving through curves (commonly known as S-turns). Some regions may also include a sixth item: highway toll card collection.

How much horsepower does the 4102 engine have?

4102 engine is 120 horsepower, 4 represents the number of engine cylinders, and 102 represents the cylinder diameter. The following is an introduction to engine-related content: Energy conversion: An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. Device: Engines can be used both as power generation devices and as entire machines including power devices (e.g., gasoline engines, aircraft engines). The engine was first born in the UK, so the concept of the engine also originates from English, and its original meaning refers to that kind of 'mechanical device that generates power'.
