What are the standards and requirements for straight-line driving in Subject Three?

[Ronan]

The examination requirement for straight-line driving in Subject Three is that within the test driving distance, the deviation of the vehicle body from the distance to the side lines on both sides must not exceed 30 centimeters (meaning the vehicle body must remain almost perfectly parallel to the side lines during the drive), and the steering wheel swing must not exceed 5 degrees. Photos for the driver's license cannot be taken with white clothes. Below is some information about the driver's license test: 1. Subject One: Road traffic safety laws, regulations, and related knowledge test, a written test conducted on a computer, with a full score of 100, and a passing score of 90 or above (including 90). 2. Subject Two: Field driving skill test, conducted with an actual vehicle in a designated area, with results categorized only as pass or fail. It includes five mandatory and sequentially conducted tests: reversing into a garage, parallel parking, S-curve driving, right-angle turning, and hill start and stop. The full score is 100, with a passing score of 80 or above (including 80). 3. Subject Three: Road driving skill test, conducted with an actual vehicle on a road or simulated area, with a full score of 100. The passing scores are 90 or above for large buses, 80 or above for large trucks, and 70 or above for other vehicle types. 4. Subject Four: Knowledge of safe and civilized driving, a written test with a full score of 100, and a passing score of 90 or above (including 90).

Maintaining straight-line driving is quite important in the Category 3 driving test. I remember my instructor emphasizing several key points. The speed should be controlled between 30 to 40 kilometers per hour, avoiding sudden acceleration or deceleration. The steering wheel must be held steady with minimal movement—keep adjustments under 5 degrees to ensure the vehicle moves straight. Focus your gaze far ahead, such as on a target 50 meters in the distance, rather than constantly checking the dashboard or steering wheel. During the test, the examiner will ask you to drive a straight section while maintaining a position within 30 centimeters of the lane centerline for 10 to 20 meters. This evaluates basic control skills to prevent swerving and potential accidents on the road. When practicing, start in an open area and gradually increase the distance to adapt to the speed. Develop the habit of making small, slow corrections if you drift—avoid sharp turns. In short, the key is to stay relaxed, focused, and not let nerves ruin your performance.

I just passed the third driving test, and straight-line driving isn't actually that difficult, but the standards are quite specific. The speed must be steady between 20-35 km/h, and you need to hold the steering wheel lightly without excessive corrections, otherwise the examiner will deduct points. The test requires driving on a straight road for 15 to 20 seconds without the vehicle weaving or deviating from the lane. I recommend focusing on a fixed point ahead, like a distant tree or building, to naturally maintain a straight path. Also, pay attention to sitting upright and avoid hunching or twisting around. During practice, simulate real scenarios as much as possible, including coordinated actions like checking turn signals, to improve overall skills. Don’t underestimate this—it builds good driving habits, prevents high-speed loss of control, and prioritizes safety. The feeling after passing is amazing, like mastering the soul of driving!

As someone who has trained many students, the core of straight-line driving is maintaining steady direction and speed. The test criteria require minimal steering wheel movement and the vehicle to drive straight without exceeding specified deviation limits. Typically, you'll drive about 30 meters at a consistent speed of 25 km/h. It's essential to focus on a distant reference point while using peripheral vision to check the mirrors for safety. Avoid gripping the steering wheel too tightly; a light hold is sufficient. The key to practice is starting at low speeds and gradually increasing to develop instinctive control. These techniques help avoid unnecessary bumps in everyday driving.

During the driving test for Subject 3, the key point of straight-line driving is to avoid veering off course. The criteria are maintaining a constant speed and keeping the direction straight, without constantly adjusting the steering wheel. The examiner will designate a section of the road where you need to keep the car within the lane at a speed between 20-40 km/h. My advice is to relax and treat it like normal driving. Pick a distant target to focus on while driving, and you'll naturally go straight. Remember not to panic or let your hands shake. This helps develop control skills, making future driving smoother. Simply put, it tests basic skills—nothing too complicated.

My child just passed the driving test, and I'm very clear about the standards and requirements for straight-line driving. The speed should be controlled between 20-35 km/h, and the direction should be stable without swaying left or right with deviations exceeding 30 cm. During the test, you drive a straight section of road, usually more than 15 meters, with only minor adjustments to the steering wheel. The requirement is to focus your gaze 50 meters ahead and avoid looking down or around. This exercise cultivates good driving habits to prevent future accidents from sharp turns. For daily practice, it's recommended that parents accompany the learner, starting at low speeds and gradually increasing the challenge. Safety first, as developing good habits benefits you for life.
