How many meters does the straight-line driving in Subject 3 end?

[StNaomi]

There is no fixed distance for straight-line driving in Subject 3, but it is approximately around 100 meters. The main challenge of this test item is to keep the vehicle moving in a straight line. Some people think that driving at a slower speed can ensure straight-line driving. However, it is important to note that there is also a speed requirement for straight-line driving, and the vehicle must reach the specified speed to pass. Below is relevant information: Straight-line driving test rules: If the direction control is unstable and the vehicle cannot maintain straight-line driving, the test is directly failed; if the specified speed is not maintained, 10 points are deducted; if the vehicle deviates more than 30 cm during driving, the test is directly failed. Subject 3 test content: preparation before starting, light simulation test, starting, straight-line driving, gear shifting operation, lane changing, pulling over, driving straight through intersections, left turns at intersections, right turns at intersections, passing through pedestrian crossings, passing through school zones, passing through bus stops, meeting vehicles, overtaking, making U-turns, and night driving.

I just finished the third subject test not long ago, and I remember the straight-line driving section particularly clearly. The test standard requires a distance of 100 meters, but in actual experience, since the speed is around 30km/h, it only takes about ten seconds. The key is to keep the vehicle in the center of the lane during this time, with steering wheel adjustments limited to no more than 5 degrees. Once during practice, my coach specifically measured it with a tape measure—from the moment the voice announced 'Please maintain straight-line driving' until the next prompt, it was exactly 100 meters. Many trainees tend to relax in the last few meters, resulting in wasted effort, so I recommend focusing on a fixed distant reference point throughout the entire section.

As a driving instructor, I often tell students that the straight-line driving distance is exactly 100 meters. This distance requires simultaneously accomplishing three things: maintaining a steady speed of around 35 km/h, steering wheel fluctuation less than 3 centimeters, and vehicle body deviation not exceeding 30 centimeters. The test vehicle is equipped with a GPS positioning system that precisely measures the distance from the moment the instruction is given. Once, I specifically brought a rangefinder for a student to confirm the start and end points, and the results proved that the electronic system is more accurate than human judgment. It's worth adding that this section feels longer during rainy-day tests.

The straight-line driving section in the Subject 3 test is indeed only 100 meters long, but don't underestimate this distance. Last month, I failed twice here: the first time due to gripping the steering wheel too tightly causing the car to wobble, and the second time because I ended the operation prematurely due to nervousness. Later, I realized the key is to glance at the lane markings with peripheral vision instead of staring rigidly at the front of the car. For students like us with less coordinated hands and feet, it's better to start adjusting the direction 200 meters in advance. Additionally, road conditions at different test sites can affect the difficulty; for example, sloped sections test control more.

When accompanying family members to practice for the Subject 3 driving test, I specifically researched the straight-line driving rules. The standard distance is 100 meters, equivalent to one lap in a standard swimming pool. Interestingly, the examination system is quite intelligent: it automatically passes the test when it detects the vehicle has traveled 100 meters continuously without deviating from the lane. I recommend beginners visualize this section as an airplane runway—maintaining a steady speed without unnecessary adjustments is key. By the way, veteran drivers mentioned they used to rely on cement utility poles as reference points, but now with clearer road signs, it's actually simpler.

The straight-line driving part during the driving test really gave me a hard time. Later, when I became a safety officer, I learned the detailed rules: from the moment the system issues the command, you must maintain a straight-line distance of 100 meters. In actual teaching, I found a common misconception—many people think the endpoint is the next road sign, but in reality, each test site has hidden markers. During training, it's best to have the instructor point out the specific start and end positions and measure them with your own steps. Another lesser-known fact: if the car in front suddenly slows down, forcing you to reduce speed, the distance measurement will pause until you resume the required speed.
