How many times do you need to use the turn signal during the entire Subject 2 driving test?

Will reversing 2 meters at the ramp entrance be captured by cameras?

Reversing 2 meters at the ramp entrance will be captured by cameras. Reversing is not allowed on highways as it is extremely dangerous. Below are precautions for driving on highways: Stay informed about road conditions: Before driving, it is crucial to obtain road condition information in advance. If TV and radio updates are not timely enough, you can call the highway hotline for inquiries. Especially during foggy seasons, it is even more important to check road conditions beforehand to avoid unnecessary detours or exits after getting on the road. Avoid fatigue driving: The enclosed environment of highways tends to increase speed, requiring prolonged high concentration, fixed driving posture, and monotonous operations, which can easily lead to both psychological and physical fatigue. Coupled with bad weather, the risk of traffic accidents increases. Therefore, when driving on highways, it is recommended to take a break every 2 hours to relieve fatigue and maintain a good mental state.

What does 'No centerline urban 3 public 4, with centerline urban 5 public 7' mean?

'No centerline urban 3 public 4' means that the speed limit on urban roads without a centerline is 30 km/h, and the speed limit on highways is 40 km/h. 'With centerline urban 5 public 7' means that the speed limit on urban roads with a centerline is 50 km/h, and the speed limit on highways is 70 km/h. Speed regulations: The maximum legal driving speed for cars in China is 120 kilometers per hour, and this speed is only allowed on highways. In general urban roads, the speed limit is usually 50 or 60 kilometers per hour. Drivers must adhere to the speed limits when driving on roads. Precautions: Driving habits should be gentle, avoiding aggressive driving behaviors such as sudden acceleration, sudden braking, and sharp turns. Aggressive driving can cause the engine, brakes, throttle, steering, and chassis systems to react and move violently without proper break-in, potentially damaging components within these systems. These delicate components are often difficult to repair effectively.

What does the 'shaft' in axle mean?

Axis is one of the main components in machinery. Generally a metal round rod, wheels and other rotating parts revolve around it or rotate with it. Introduction to wheelbase: Wheelbase is the horizontal distance between the center lines of axles on a locomotive or vehicle. It is divided into: rigid wheelbase, bogie wheelbase and total wheelbase. Rigid wheelbase refers to the horizontal distance between the center lines of the front and rear axles within the main frame of a frame-type locomotive. Wheelbase should not be too long: To facilitate passing through curves, the rigid wheelbase should not be too long. Bogie wheelbase refers to the distance between the center lines of the two axles at both ends of a bogie. Total wheelbase refers to the horizontal distance between the center lines of the front and rear axles of a locomotive; rigid wheelbase is the distance from the foremost axle to the rearmost axle that remains parallel during train operation. If the rigid wheelbase is too long, it will increase pressure on the tracks when turning, and may even cause derailment.

What is an Axle?

An axle is a shaft that transmits power between the main reducer (differential) and the drive wheels, mostly solid. Its inner end is connected to the differential's side gear, while the outer end is connected to the drive wheel hub. The axle of a steering drive axle needs to be segmented and connected by constant velocity universal joints; the axle of a swing axle drive axle not only needs to be segmented and equipped with universal joints but also requires telescopic splines or telescopic constant velocity universal joints. Introduction to Wheelbase: Wheelbase is the horizontal distance between the centerlines of the axles of a locomotive or vehicle. It is divided into: rigid wheelbase, bogie wheelbase, and total wheelbase. The rigid wheelbase refers to the horizontal distance between the centerlines of the front and rear axles within the main frame of a frame-type locomotive. Wheelbase Should Not Be Too Long: To facilitate passage through curves, the rigid wheelbase should not be too long. The bogie wheelbase refers to the distance between the centerlines of the axles at both ends of a bogie. The total wheelbase refers to the horizontal distance between the centerlines of the front and rear axles of a locomotive; the rigid wheelbase, on the other hand, is the distance from the foremost axle to the rearmost axle that remains parallel during train operation. If the rigid wheelbase is too long, it increases the pressure on the tracks during turns and may even lead to derailment.

Is it true that new energy water can replace gasoline?

New energy synthetic hydrogen-powered water cannot replace gasoline. How to choose gasoline: The Jetta VS7 can use 92-octane gasoline, but using 95-octane gasoline provides better engine protection. Even high-compression engines can use lower-octane gasoline, but you should not blindly choose gasoline based on compression ratio alone. Simply follow the manufacturer's recommendations for refueling. Selection between 95-octane and 92-octane gasoline: 95-octane gasoline consists of 95% isooctane and 3% n-heptane. High-compression engines should use high-octane gasoline. Using low-octane gasoline in high-compression engines may cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving power. This type of gasoline is suitable for premium vehicles. 92-octane gasoline has an octane rating of 92 and contains 8% n-heptane, making it suitable for mid-range vehicles.

What are the features of an electronic driver's license?

Electronic driver's licenses have three features: uniformity, real-time capability, and security. The application of electronic driver's licenses will achieve 'three conveniences': First, convenient application: Drivers in three pilot cities can log in to their personal accounts on the 'Traffic Management 12123' App to obtain an electronic driver's license. When applying, the driver's license should be valid, and applicants must submit their electronic ID photo taken within the last six months. Second, convenient display: Electronic driver's licenses can be used in various scenarios such as law enforcement management and public services. Drivers can log in to the 'Traffic Management 12123' App to query and display their electronic driver's license in real-time. The generated electronic driver's license on the App can also be used offline. Third, convenient use: When handling traffic management affairs, driving, or renting vehicles, public security traffic management departments and related industries can verify the electronic driver's license online. During law enforcement inspections, for drivers presenting an electronic driver's license, public security traffic management departments will no longer check the paper driver's license, instead verifying the driver's license information online through law enforcement terminals.
