Cracks under 10 centimeters can pass the motor vehicle annual inspection, while cracks exceeding 10 centimeters will fail the inspection. Motor vehicles must undergo annual inspections after reaching the specified usage period. Only after completing the annual inspection can the vehicle be legally driven on the road; otherwise, it is prohibited. The main aspects of the vehicle annual inspection include: 1. Checking whether the engine, chassis, body, and their accessories are clean, complete, and functional, whether the paint is uniform and aesthetically pleasing, whether major components have been replaced, and whether they match the initial inspection records; 2. Verifying whether the vehicle's braking performance, steering control, lights, exhaust, and other safety features comply with the "Technical Conditions for Safe Operation of Motor Vehicles"; 3. Examining whether the vehicle has undergone modifications, alterations, or transformations, whether the driving license, license plate, and vehicle registration records match the actual condition of the vehicle, and whether any changes have been approved and documented; 4. Inspecting whether the license plate, driving license, and enlarged license plate markings on the vehicle are damaged, altered, or illegible, and whether they need replacement.

I've been driving for over thirty years and have dealt with many glass issues. Whether a cracked windshield can pass the annual inspection mainly depends on the size and location of the crack. If the crack is directly in front of the driver, exceeds ten centimeters in length, or obstructs the view, the inspector will definitely fail it; small edge cracks might barely pass, but this also depends on the strictness of the local inspection standards. For example, last year, my old buddy's car had a small crack in the windshield that didn't seem obvious, but it was flagged during the inspection, requiring immediate repair before proceeding. I think the best approach is to visit a repair shop early—replacing the windshield isn't too expensive, so don't gamble with luck. Safety comes first; if the crack spreads while driving, blurred vision could be very dangerous.

Last time my windshield got a small chip from a rock, I thought nothing of it. But when I checked the regulations before the annual inspection, I realized it might be an issue. If the crack is large or right in the driver's line of sight, it will definitely fail the inspection. Smaller cracks at the edges might pass, depending on local standards. I tried a DIY repair kit—cheap but not very effective—and later realized it's better to spend a bit more for professional repair. Driving with impaired visibility is scary, and an accident would be far worse. Next time, I'll deal with it right away to save the hassle.

Whether a cracked windshield passes the annual inspection depends on the severity of the crack. If it's too long or within the driver's line of sight, it generally won't pass due to significant safety hazards. I recommend checking the crack before the inspection. For minor issues, you can use a repair kit yourself, but for major problems, replace the windshield immediately. Don't wait until the inspection fails to act. Safety comes first.

I always remind myself that vehicle safety is no trivial matter. Cracks on the windshield can make it difficult to pass the annual inspection, especially if they are large or obstruct the view. According to regulations, this is directly related to driving risks—just imagine how terrible it would be if the glass shattered and hurt someone. Getting it fixed early doesn't cost much but ensures safety. Failing the annual inspection might require a retest, which is just more hassle and not worth it.

From a cost-saving perspective, a small crack on the windshield might pass the annual inspection with minor repairs, but a large crack will definitely fail. I've done the math: DIY repairs cost just a few dozen yuan, but the results are inconsistent; professional replacement costs a few hundred yuan, but it eliminates the hassle of failing the inspection and the cost of re-inspection. In the long run, investing in safety is worth the price.
