Which Gear to Use When Driving on City Roads?

When starting on city roads, use 1st gear, then shift to 2nd gear. Shift to 3rd gear when exceeding 40 mph, and you can use 4th and 5th gears when exceeding 60 mph. The specific gear depends on the vehicle speed, which in turn depends on road conditions and traffic signs. The Relationship Between Gears and Speed: Shifting gears on various roads cannot be generalized. Consider the engine and transmission indicators of the vehicle. Persistently driving at low speeds can also cause wear and tear on the vehicle. Additionally, account for road conditions, whether they are open or congested. Driving Tips: Appropriately reduce speed when encountering intersections, traffic signals, or congested areas (such as schools or markets). Maintain a reasonable distance from vehicles in front and behind. Also, drive at a reduced speed during adverse weather conditions.

Can the differential lock be engaged in high gear?

Differential lock cannot be engaged in high gear. The differential lock is used for extrication, and the four-wheel drive differential lock must use low gear when locked. Introduction to differential lock: It is the locking mechanism of the differential, used to lock the inter-wheel differential (between the left and right half shafts) or the inter-axle differential (between the front and rear drive axles), to deal with situations where one or more wheels lose traction and cannot be extricated. Function of differential lock: When a car is driving on a curve, the outer wheels travel a longer distance than the inner wheels, and the corresponding speed is also higher than that of the inner wheels. The differential lock can reasonably distribute torque between the left and right wheels when the vehicle is turning, to achieve better turning performance. It can also ensure that all wheels of the vehicle receive effective power in off-road conditions, helping the vehicle to extricate itself from difficult situations as quickly as possible.

What Causes the Idle Speed to Increase When Depressing the Clutch to Shift Gears?

The reason for the idle speed increasing when depressing the clutch to shift gears is that the throttle is not fully released. When driving, the engine has rotational inertia (momentum) during operation. However, because there is a load (before the clutch is depressed), releasing the throttle will cause the speed to decrease. But during the process of speed reduction, suddenly depressing the clutch all the way results in significant rotational inertia, yet the load is suddenly removed, causing the speed to slightly increase instead. Solution: After fully releasing the throttle, wait a moment before depressing the clutch to shift gears. Essentially, it's a matter of coordinating the timing between the throttle and the clutch. Idle Speed Overview: Idle speed is an operational state of a car, referring to the engine running in neutral. The engine speed during idle is called the idle speed. The idle speed can be adjusted by modifying the throttle opening size, among other methods. Idle speed means the engine is "producing power without doing work."

Is driving at 60 mph fast?

Driving at 60 mph is not fast. The concept of 60 mph: In China, whether it's 60 kilometers, 60 mph, or 60 miles, they all refer to 60 kilometers. However, the term '60 mph' generally evolved from '60 miles'. Abroad, speedometers are calibrated in miles. But there is a difference between miles and kilometers. 'Mile' is a transliteration of the English word 'mile', meaning a unit of distance. 1 mile = 1605 meters = 1.605 kilometers. Therefore, the actual speed of 60 miles is 96.3 kilometers per hour. '60 mph' refers to 60 kilometers per hour, which converts to 16.67 meters per second. Normal human reaction speed: The reaction speed of a normal person to sudden events is generally around 80 mph.

Should You Steer with Your Left Hand or Right Hand While Driving?

When driving, the steering wheel should be operated with both hands. Using only one hand is an incorrect driving method. The necessity of steering with both hands: In emergency situations, steering with one hand can easily cause the wheel to slip, which is very dangerous. Additionally, gripping the steering wheel firmly with both hands is a prerequisite for maintaining the correct driving posture. When seated in the driver's seat, the hips serve as one pivot point, while the hands gripping the steering wheel act as the other two pivot points. This three-point support is the most stable and ensures driving safety. Correct steering operation: Hold the wheel in the "9 and 3 o'clock" position. Do not release the wheel during turns; instead, move your hands along with the wheel's rotation, including when straightening it. Only in this way can steering and straightening actions be performed most accurately and quickly.

How many days does it usually take to learn reversing into the garage in Subject 2?

Generally, learning to reverse into the garage takes about 4 class hours per day, and it usually takes about a week to master, depending on individual circumstances. Criteria for reversing into the garage: Failing to follow the prescribed route or sequence results in disqualification; the vehicle going out of bounds, failing to enter the garage, or stopping midway results in disqualification; taking more than 4 minutes to complete the reversing into the garage results in disqualification. Standard garage dimensions: The standard dimensions for reversing into the garage in Subject 2 are a garage length of 5.25 meters and a width of 2.3 meters. No stopping during the test: There is no time limit for reversing into the garage, but it's important to note that stopping midway is not allowed. If the wheels remain stationary for 3 seconds, the system will judge it as stopping midway, so controlling the speed is crucial.
