Braking is not allowed during straight-line driving in Subject 3. Below are the scoring standards for straight-line driving in Subject 3: 1. Failure to maintain straight-line driving: Inability to keep the vehicle moving straight due to unstable steering control results in disqualification; 2. No action taken when the vehicle ahead brakes: Failure to promptly decelerate when the vehicle ahead brakes results in disqualification; 3. Not observing traffic conditions: Not timely observing the rear traffic conditions through the interior and exterior rearview mirrors deducts 10 points; 4. Failure to detect obstacles: Not promptly detecting road obstacles or not taking timely deceleration measures upon detecting road obstacles deducts 10 points.

In the straight-line driving section of the road test (Subject 3), it is acceptable to brake, but only with valid justification. For instance, if a vehicle suddenly changes lanes ahead or a pedestrian crosses the road, you must slow down promptly to ensure safety. During the test, the examiner monitors speed stability closely. Unjustified braking may be penalized as improper speed control. With years of driving experience, I recommend cultivating the habit of maintaining steady speed on straightaways—focusing your gaze far ahead helps stabilize steering, reducing unnecessary braking. Even when braking is necessary, apply gentle pressure to avoid sudden vehicle sway that could disrupt balance. Regular practice of this technique helps prevent test errors while fostering safe driving instincts.

During the straight-line driving section of the driving test (Subject 3), you are indeed allowed to apply the brakes, primarily to respond to actual hazards. For example, slowing down when encountering a red traffic light ahead or obstacles blocking the path. However, avoid unnecessary braking as the examiner may deduct points for unstable speed control. I experienced a similar situation during my own test, and my instructor repeatedly emphasized that maintaining a steady speed is crucial—always consider the necessity before braking. For beginners, it's recommended to focus on controlling the accelerator to maintain a stable speed of 30-40 km/h. If deceleration is necessary, opt for gentle braking rather than sudden stomps to prevent vehicle sway. Additionally, remember to check the rearview mirror to monitor the distance of vehicles behind you. This approach ensures smoother operation and increases the chances of passing the . With experience, you'll naturally develop a better sense of judgment to avoid potential issues.

In the straight-line driving section of Subject 3, braking is allowed but only in emergency scenarios such as avoiding pedestrians or vehicle intrusion. Unnecessary operation will result in point deductions affecting the score. I always adhere to the principle of safety while driving, as unnecessary braking may disrupt straight-line balance and even cause rear-end collision risks. Maintaining a constant speed, focusing on the target line of sight, can ensure a smooth pass. Do not easily use the foot brake unless truly necessary. Developing good habits is very important.

Applying brakes during straight-line driving in Subject 3 is feasible, especially in collision avoidance scenarios, but unnecessary braking may lead to point deductions due to speed fluctuations as the system monitors vehicle dynamic stability. Having observed vehicle behavior, I note that braking alters power distribution, and slight deviations might be detected. It's advisable to minimize brake usage during practice, maintaining steady throttle control for higher test success rates and improved body coordination. Reserve decisive actions for critical moments to ensure safety and reliability.

In the straight-line driving section of the driving test (Subject 3), you can apply the brakes, but only in reasonable situations such as simulating emergency avoidance. Otherwise, the examiner may deem it improper operation and deduct points because it affects the smooth flow of constant speed. When I was first learning to drive, I once braked unnecessarily and was reminded of the mistake. Later, I focused on maintaining steady throttle to reduce the need for braking, which made it easier to keep the car straight. Developing this habit in daily practice helps avoid nervousness during critical moments and allows for automatic adaptation during actual driving, ensuring safety and smoothness.
