How to Interpret the Lines on a Reversing Camera?

Learning to interpret the lines on a reversing camera is an essential skill for driving. Here is a detailed introduction to the markings on a reversing camera: 1. Red line: This can be regarded as a warning line, with the bottom of the line located 30 centimeters from the rear of the vehicle, indicating that you should not reverse further. 2. Yellow line: This can be seen as a deceleration line, with the bottom of the line 60 centimeters from the rear of the vehicle, allowing you to slow down and continue reversing. 3. Green line: This can be considered a safety line, with the bottom of the line positioned at a distance far from the rear of the vehicle, indicating that you can continue reversing. If your reversing camera displays blue lines, there is no need for confusion, as their meanings are essentially the same as above—the line closest to the rear of the vehicle is the warning line, which will prompt you to stop reversing.

After driving for so many years, I use those lines on the reverse camera every day. The red one is the most eye-catching, indicating that the rear of the car is about to hit something, with a distance of less than half a meter—when you see it, you need to hit the brakes immediately. The yellow line is the warning zone, about 1-1.5 meters away, at which point you should slow down and reverse carefully. The green line is beyond 2 meters, representing the safe zone, where you can operate normally. These lines also curve to show the trajectory based on the steering wheel's turn, making the wheel direction clear at a glance. When reversing in a tight parking lot, I always keep an eye on the screen: if the obstacle is still on the green line, I continue; if it drops to the yellow line, I proceed with caution; if it touches the red line, I stop immediately. Combined with checking the rearview mirror, it’s efficient and safe. Sometimes, if the camera is dirty, the lines may shift—I just wipe it clean with a damp cloth. If they’re still off, I take it to the shop for calibration. Newbie friends often ask me how to read them, and I tell them to practice more and combine visual judgment, not just rely on electronic aids.

The guidelines on the reversing camera are crucial aids for safe driving. The red line indicates a very close distance, typically within 0.5 meters, signaling danger and requiring immediate stopping. The yellow line, positioned around 1.5 meters, serves as a warning distance. The green line, extending beyond 2 meters, indicates a safe zone for proceeding. I find these color-coded lines intuitive and easy to understand, enabling quick distance judgment during reversing and reducing the risk of collisions caused by blind spots. For instance, in a crowded parking garage, if an object is outside the green line, I can reverse with confidence; approaching the yellow line calls for caution; and touching the red line necessitates stopping to inspect. The lines also feature dynamic trajectory functionality—they curve as the steering wheel turns, helping me visualize the rear movement direction. Regular cleaning of the camera lens is essential, as dust can impair accuracy. It’s advisable to maintain the system periodically to ensure everything functions properly.

When I first got my driver's license, the reversing camera lines were a huge help. The red line is the warning point, indicating you should stop when very close; the yellow means be cautious; and green means you can continue reversing. Combined with the dynamic trajectory lines, they bend as you turn the steering wheel, showing the wheel direction. With more practice, you'll get used to it—don't just rely on the screen, use your mirrors too.
