Driving with one missing rearview mirror is illegal. Article 21 of China's Road Traffic Safety Law stipulates that before driving a motor vehicle on the road, the driver must carefully inspect the vehicle's safety technical performance. It is prohibited to drive a motor vehicle with incomplete safety facilities or components that do not meet technical standards, as such vehicles pose safety hazards. How to use rearview mirrors: When parking, starting, overtaking, turning, or making a U-turn—essentially whenever the driving route is about to change—always signal accordingly and pay close attention to the rearview mirrors to stay informed about traffic conditions on both sides and behind. This helps avoid being caught off guard by sudden situations. Before driving, adjust the position and angle of the rearview mirrors. When passing through narrow roads or bridges with non-motorized vehicles or pedestrians on either side, slow down and check the rearview mirrors appropriately. Maintain necessary lateral spacing from non-motorized vehicles or pedestrians. Keep a safe distance from the vehicle ahead and use the rearview mirrors to observe and judge the following distance of vehicles behind you. This ensures you can handle situations confidently and prevent rear-end collisions. Before applying predictive braking, check the rearview mirrors to note the position and relative speed of vehicles behind you, then decide on the appropriate braking measures to avoid rear-end collisions. At intersections with high traffic conflicts, reduce speed, observe pedestrians and vehicles on both sides, and proceed safely. Functions of rearview mirrors: While driving, the driver can observe road conditions on both sides through the rearview mirrors to perform lane changes, overtaking, and other maneuvers. During parallel parking or reversing into a parking space, the rearview mirrors help align reference points. Pay special attention to the center rearview mirror, which helps judge the distance to the vehicle behind. When the rear vehicle's front wheels are just visible in the center rearview mirror, the distance is approximately 13 meters. When the grille is visible, the distance is about 6 meters. When the grille is just out of view, the distance is roughly 4 meters.

Driving with a missing side mirror is highly discouraged. As someone with over a decade of driving experience, I've witnessed numerous accidents caused by this issue. Side mirrors aren't just decorations – they're crucial for monitoring rear traffic and blind spots. Missing one creates a dangerous blind zone while driving. Legally, vehicles must maintain a complete mirror system including both side mirrors and the center rearview mirror. Police may issue fines or penalty points for violations. Practically speaking, driving without it forces you to turn your head more when changing lanes, reversing, or parking, increasing distraction and collision risks with other vehicles or pedestrians. My neighbor once drove to an urgent meeting with a broken mirror and nearly sideswiped a truck on the highway. I strongly recommend stopping driving immediately, contacting an auto shop for replacement parts, and prioritizing safety. Make it a habit to regularly check mirror tightness and secure any loose ones.

Last month, the left side mirror of my old car got stolen, and over the weekend, I accidentally scraped it against a roadside pole while out for a drive—it felt awful. Driving home was nerve-wracking; every lane change required craning my neck like a pretzel, terrified a car might emerge from the blind spot, especially at busy intersections with honking and flashing lights that left my palms sweaty. Simply put, driving without a mirror is more exhausting and dangerous, and it’s outright illegal to drive with such a hazard. Thankfully, I searched online when I got back, bought a compatible used mirror, and installed it myself for less than fifty bucks. If you can’t fix it immediately, don’t risk driving—call a tow truck or use public transit instead. Driving is hard enough; missing equipment just adds chaos.

Don't drive with a missing side mirror - let me explain the repair perspective. Every vehicle requires a complete rearview system to monitor blind spots, including side mirrors, center mirror, and possibly rearview cameras. Missing one creates a huge visibility gap. Common causes are collisions, aging, or electric component failures. First check if the mirror is loose/damaged; for power mirrors, test fuses or switches. Repair is simple: most models' mirrors can be ordered online for replacement (costs just tens of yuan), or have a technician install one in 10 minutes at a shop. Never risk driving - it's illegal and accident-prone, especially when reversing where danger doubles. Regularly check mirror conditions during car washes to prevent minor issues becoming major troubles.
