What's the reason for failing facial recognition during the driver's license test?

[DiEdward]

Facial recognition failure may be caused by the following reasons: 1. Photo discrepancy: The difference between the base photo and the on-site photo is too large, such as age differences. 2. Makeup: For female candidates, factors like wearing makeup, glasses with black frames, or having straight bangs may affect recognition. 3. Poor lighting: The verification environment may have insufficient lighting. 4. Side profile: During the recognition process, make sure to face the device directly, avoiding side angles or tilting your head up/down. Avoiding these issues should ensure successful recognition.

I also encountered facial recognition failure during my last driving test (Subject 3), which is actually quite common. Failed recognition mainly occurs when the system camera's identification conditions aren't met - overly bright or backlit environments affect shooting quality, while bangs covering the face or glasses reflecting light may also cause recognition failure. Improper seat height adjustment during the test creates incorrect angles, preventing the camera from capturing full facial contours. Another frequently overlooked factor is facial expression - keeping a stiff face without expression or exaggerated smiles both affect system matching. Significant differences between ID photos and current appearance (like dyed hair or major weight changes) also cause issues. Before entering the examination room, adjust your appearance, sit squarely facing the camera, follow prompts to blink slowly or nod gently. If recognition fails, stay calm and let staff manually input your information.

As a veteran driving school instructor, I've seen too many students get stuck at the facial recognition stage. The root cause is that the equipment isn't smart enough—direct sunlight on the outdoor test site can overexpose the camera lens. Sweat or oily skin on the examinee's face can also cause glare that interferes with recognition. Others wear colored contacts or heavy makeup, which differs too much from their registration photo and leads the system to flag them as impersonators. If recognition fails, don't attempt multiple times in a row, as this can easily lock the system. The correct approach is to step back, adjust your position, wipe your face dry with a tissue, and wait for stable lighting before trying again. Even during regular practice, pay attention to sun protection to avoid having a tanned face on test day, which can affect recognition accuracy. Test centers have manual verification channels in their backend systems; if all else fails, opt for human review.

Facial recognition failures are the most annoying. I had to deal with it three times during my driver's license test. The issue lies in the inadequate calibration of the exam room equipment—people with round faces or high cheekbones like us are more prone to misidentification. Additionally, having your phone's hotspot on can interfere with the device's signal, and many beginners forget the rule about turning off all electronic devices during the test. During recognition, sit upright without moving around, maintaining a distance of about half a meter is ideal. I recommend arriving early on the exam day to familiarize yourself with the angles using the simulation equipment. Later, I realized that sunscreen should be fully absorbed before entering the exam room, as oily reflections can interfere with infrared recognition. Overlooking these details might result in a wasted trip.
