When the right starting sensor line appears and aligns with the lower edge of the left rearview mirror, turn the steering wheel fully to the right. Observe the right rearview mirror, and when the far right line becomes visible, if the distance between the vehicle body and the parking space corner is less than 30cm, turn the steering wheel back halfway.

I've been driving pickup trucks for many years, and the key to judging the 30cm distance when reversing into a garage is finding the right visual reference point in the rearview mirror. My usual method is observing the alignment between the rear wheels and the ground line—when the rear wheels just cover the front edge of the garage boundary line, that's approximately 30cm. Mastering this point requires practice since garage heights vary, and in low light, you should also pay attention to changes in the shadow at the rear of the vehicle for additional reference. Beginners can start practicing from 50cm and gradually move closer; with muscle memory developed over time, accuracy will come naturally. Always reverse slowly, listening to the engine sound and adjusting the angle to avoid scraping. Given the large body of a pickup truck, never rely on gut feeling—use actual reference points for safer maneuvering.

When I frequently make deliveries and reverse into parking spaces with my pickup truck, I personally find the most effortless method to gauge the 30cm point is by using the reversing camera system. The screen displays distance indicator bars, with the green line typically marking the 30cm position—simply stop there. If this equipment isn't available, I rely on checking the side mirrors to observe the distance between the truck's rear corner and the wall—when the corner vertically aligns with a ground marker, that's the accurate point. Always remember to clean your mirrors before parking to avoid blurred vision and misjudgment. Maintaining a snail's pace while reversing is safer, especially when combined with radar warning beeps for double assurance. Once accustomed, the pickup's high body actually makes judging distances easier.

As a car owner, I rely on fixed reference points when reversing into a parking space to gauge the 30cm distance. For example, observing the intersection point of the ground lines in the rearview mirror, and stopping when the line just disappears at the lower edge of the rear bumper. The wide tires of a pickup truck make for an easy reference, but it's important to pay attention to the garage floor's levelness and lighting conditions that may affect visibility. For first-time attempts, placing a small object as a target point aligned with the side of the vehicle can be helpful. Always reverse at a slow speed and make slight steering adjustments to optimize the viewing angle, ensuring safety.
