The principle of the reverse gear is to add an additional gear between the driving gear and the driven gear. In other words, gears 1 to 5 are forward gears driven by two gears, while the reverse gear is driven by a single gear. Below is an introduction to reversing: 1. Introduction: Reversing refers to the backward movement of a motor vehicle. It also refers to the act of "transferring" during travel, i.e., switching from one vehicle to another. Reversing is more challenging than driving forward, mainly due to limited visibility. 2. Four hazards to prevent: Collision prevention: When shifting in reverse, pay attention to the width of the target position and assess the obstacles behind and on both sides of the vehicle relative to the safe position of the rear wheels. To avoid collisions, scrapes, or falling into ditches, it may be necessary to have someone guide the vehicle from behind. Garage scrape prevention: When reversing into a garage, if visibility is good, you can directly observe and judge through the rear window. If visibility is poor and you cannot see clearly, open the door and assess the position of the vehicle in the garage from one side while also checking the other side through the rearview mirror to prevent scraping the garage or other vehicles. Side scrape prevention: When reversing around a corner, pay attention to the situation on the inside of the turn and behind the vehicle. Use the rearview mirror to monitor both sides of the vehicle and time the steering wheel correctly to avoid rear-end collisions or side scrapes. Ditch fall prevention: When reversing to turn around, if the road is wide enough, you can judge the position of the rear or wheels directly through the rearview mirror. If multiple forward and reverse movements are needed, step out to check the safe distance between the wheels and the road to prevent falling into a ditch.
