How to Determine the Distance Between the Rear of the Car and Obstacles When Reversing?
2 Answers
When reversing, there are several methods to determine the distance between the rear of the car and obstacles: 1. Using the reversing radar: If the vehicle is equipped with a detection radar, when the radar sound starts, the distance is approximately 30 centimeters. If the sound is very rapid, the distance is only about 10 centimeters. 2. Using the reversing camera: If the vehicle has a reversing camera, reversing becomes very convenient as the rear situation is clear at a glance with no blind spots. 3. Using the rearview mirrors: When using the rearview mirrors to judge, combine the left and right rearview mirrors with the interior rearview mirror for observation, with the interior rearview mirror being the primary reference. When the driver can just see the rear windshield in the interior rearview mirror, the distance is approximately 0.5 meters.
As a beginner driver, I get a bit nervous when reversing, so I use some tricks to gauge the distance between the rear of my car and obstacles. First, I rely on the rearview mirror to observe the size changes of objects behind me—when an object appears large in the mirror, it means the distance is already very close. I usually stop and adjust my position when it fills about one-third of the mirror. I practice in an empty parking lot, using plastic bags or boxes as mock obstacles to get familiar with my car's dimensions, especially the length from the rear to the bumper. Beginners often overlook blind spots, so I frequently glance out the window to double-check and avoid scrapes. Additionally, I’ve installed a rearview camera that shows real-time distance, which is very helpful. With more practice, it gets easier—safety first, no rush to park.
