What Are the Evaluation Criteria for Straight-Line Driving?

[DiEva]

There are 5 evaluation criteria for straight-line driving. Evaluation criteria for straight-line driving: There are a total of 5 evaluation criteria for straight-line driving. There are 2 situations that result in failure. During driving, if the steering wheel is not held steady, causing the vehicle to deviate significantly from a straight path, it is considered a failure. If the driver does not reduce speed when encountering a vehicle braking ahead, it is also considered a failure. There are 3 situations that result in a 10-point deduction. Not checking the rearview mirror for more than 20 seconds and failing to observe the situation of vehicles behind results in a 10-point deduction. Not being aware of the vehicle's speed results in a 10-point deduction. Failing to detect road obstacles in time and not taking timely measures to reduce speed results in a 10-point deduction. Techniques for straight-line driving: There are 4 techniques for straight-line driving: choosing a good reference point, holding the steering wheel steady, making minor adjustments to the direction, and controlling the speed properly.

As an experienced driving instructor, I emphasize three key scoring points for straight-line driving: steady steering wheel, correct direction, and straight vehicle alignment. During the test, the system automatically detects steering wheel movement, which must not exceed 5 degrees, or points will be deducted. The vehicle must strictly maintain center lane position—deviating more than 30 cm left or right results in failure. Within 100 meters of driving, frequent directional adjustments are prohibited; align with distant reference points in advance. Maintain a steady speed, ideally around 35 km/h, avoiding sudden acceleration or deceleration. A common mistake among students is fixating solely on the hood, causing increasing deviation. Remember: focus your gaze farther ahead, use peripheral vision to monitor lane markings, and lightly hold the steering wheel—these are crucial.

What annoys me the most when driving myself is encountering people who stubbornly maintain a straight line on uneven road surfaces. In fact, judging straight-line driving isn't just about technique but also safety awareness. When driving, pay attention to the centerline of the lane, and keep the vehicle's side-to-side sway within 30 centimeters. Don't grip the steering wheel too tightly; just hold it lightly and make minor adjustments. A speed of 30-40 km/h is most suitable—going too slow can actually make it harder to control. Especially in rain or snow, any slight deviation should be corrected immediately, but steering wheel movements must be smooth. On highways, be extra cautious—a deviation of just ten centimeters could lead to an accident. Develop the habit of regularly checking tire pressure, as good vehicle condition is essential for driving straight.

Accompanying my friend during the third driving test made me realize the intricacies of straight-line driving. The system uses GPS and gyroscopes to monitor the entire process, triggering an alarm if the steering wheel deviates by 3 degrees. The vehicle must stay in a fixed lane for about 100 meters, and swaying more than 30 centimeters left or right results in an immediate fail. What beginners should practice most is anticipation—aligning with distant road signs or tree shadows in advance. Don't stare at the dashboard; focus 300 meters ahead for stability. During the test, stay relaxed, just rest your hands on the steering wheel, and guide it gently with your fingertips. A speed of 35 km/h is recommended—too slow and the car may shake. If you feel off course, adjust by no more than 5 degrees at a time before straightening out.
