Stopping distance does not include the starting distance. The following is an extended introduction: 1. Introduction to stopping sight distance: Stopping sight distance refers to the shortest driving distance required for a vehicle to stop when encountering an obstacle ahead while driving on the same lane. Stopping sight distance can be broken down into three parts for study: reaction distance, braking distance, and safety distance. Simply put, stopping sight distance is the shortest distance required for the driver to stop before discovering an obstacle. 2. Composition of stopping sight distance: Stopping sight distance consists of three parts: the distance S₁ traveled during the driver's reaction time, the distance S₂ traveled from the start of braking to the complete stop of the vehicle (braking distance), plus a safety distance S₀ (5~10m).

Which Gear to Use When Climbing a Slope?

When climbing a slope with a car, the gear selection depends on the steepness of the slope. Here is a detailed introduction to gear selection for car slope climbing: 1. Gear selection for small slopes: When going uphill, observe the car's climbing power. Each car has its own climbing power capacity. If fourth gear provides enough power for a small slope, use fourth gear to climb. 2. Gear selection for medium slopes: If third gear provides enough power for a medium slope, use third gear to climb. If third gear is insufficient, switch to second gear (this can be done either at the bottom or on the slope, but requires coordination between the clutch and accelerator). 3. Gear selection for large slopes: For large slopes, try to use second gear if it provides enough power. If second gear is insufficient, switch to first gear to climb.

Is there a voice prompt for independent lane changing in Subject 3?

There is no voice prompt for independent lane changing in Subject 3. Here are some tips for independent lane changing: 1. Turn on the turn signal in time: Before changing lanes, turn on the turn signal for more than 3 seconds to alert the vehicles behind and avoid rear-end collisions. 2. Observe the traffic conditions: After turning on the turn signal, don’t rush to the next step. First, observe the surrounding vehicles through the rearview mirror, and also look back to check the lane you are about to enter. Only proceed with the lane change after confirming it is safe. 3. Be decisive when changing lanes: After observing everything, proceed with the lane change quickly and avoid making large steering movements. Hesitation when changing lanes can cause trouble for the vehicles behind. 4. Turn off the turn signal after completion: After completing the lane change, remember to turn off the turn signal.

What is the maximum age requirement for obtaining a driver's license?

The maximum age limit for obtaining a driver's license is 70 years old. Below are some important considerations for taking the driving test: 1. Don't forget to release the handbrake when starting: When first learning to drive, always follow the correct sequence when starting the car. Regardless of whether the handbrake was engaged when parking previously, always check and release the handbrake when starting. 2. Always fasten your seatbelt: Good habits start with wearing a seatbelt. Although it may feel uncomfortable, this small belt can save your life in the event of a high-speed collision. 3. Don't forget to engage the handbrake when parking: This issue is similar to wearing a seatbelt. During practice sessions, the training area is usually flat, and instructors might not emphasize this enough as students take turns. However, failing to correct this bad habit can lead to serious problems in real driving situations. A moment of carelessness can result in the car rolling, potentially causing damage to your vehicle or even harm to others' property or lives. The mistake may seem minor, but the consequences can be severe. 4. Correct positioning of the right foot: Driving school cars often have higher idle speeds. Instructors usually discourage students from using the accelerator during initial training, sometimes even disconnecting the throttle cable. Since the car moves at idle speed, it's very slow, and pressing the clutch can stop it immediately. Over time, many students develop the habit of keeping their right foot idle. This habit can be dangerous when driving a manual transmission car in real situations, as it may lead to delayed or incorrect braking responses during emergencies, even causing accidents by mistakenly pressing the accelerator instead of the brake. 5. Don't forget to shift to neutral when exiting the car: Forgetting to shift back to neutral or Park after stopping can cause the engine to stall. If combined with forgetting to engage the handbrake, the car might lurch forward, potentially causing damage to yourself or others.

What are the techniques for identifying several types of traffic violations in Subject 4?

Subject 4 violation judgment techniques include: when counting violations in animations, pay attention to scene transitions; extend contextual clues from questions, and focus on daily knowledge accumulation. Below are judgment techniques for Subject 4 violations: 1. Match options with question stems and eliminate sequentially: Most violation judgment questions present a scenario in the stem, requiring candidates to select all violations committed by the driver from four options, appearing in both single-choice and multiple-choice formats. The approach is to cross-reference each option with the stem and eliminate incorrect choices. 2. Extend contextual clues from question stems and emphasize daily accumulation: Sometimes question stems provide indirect clues, requiring examinees to apply common sense for independent judgment.
