Will the DMV cancel exams during heavy rainstorms?

[Frodo]

In cases where heavy rainstorms severely impair visibility at the test site, exam sessions may be appropriately canceled. Apart from thunderstorms, the test center will also suspend exam arrangements in response to national prevention and control requirements when other disasters occur. Otherwise, exams will generally proceed as scheduled during ordinary rainy or overcast weather. Here are some tips for taking the driving test (Subject 3) on rainy days: Rearview mirrors: Currently, sticking your head out of the window is not allowed, so you'll mostly rely on rearview mirrors to check behind you. However, rain can blur the mirrors, so wipe them clean before starting the exam. Windows: Avoid closing them too tightly, as this can cause fogging inside the car, impairing visibility and judgment accuracy. Pedals: Don't rush to step on the pedals immediately after getting in the car. Shake off any water from the soles of your shoes outside the car first to prevent slipping. Windshield wipers: You don't need to keep the wipers on continuously. Turn them on briefly before starting the fixed-point parking to clear rain from the windshield, then turn them off during the parking maneuver. Generally, visibility should remain adequate.

Recently, many people have asked me about taking the driving test during heavy rain. As a driving instructor with ten years of experience dealing with the DMV, I can say for certain: when heavy rain causes flooding at the test site or visibility falls below the test standards, the test will definitely be postponed. My students have experienced situations where all tests were delayed during a red alert. Specifically, the DMV has radar rainfall monitoring equipment, and if rainfall exceeds the threshold, a circuit breaker mechanism is activated—after all, how can you test parallel parking when you can't even see the markings on the test site due to heavy rain? I recommend checking the local DMV's official WeChat account before heading out; they will send a group text message no later than two hours before the test. If you encounter sudden heavy rain on the way, don't panic—contact your instructor immediately to reschedule. Never take the risk of driving the test car through deep water areas.

Having worked at the Vehicle Management Office for six years, we have three strict criteria for suspending driving tests: first, real-time wind speeds exceeding level 6; second, short-term rainfall reaching over 50 millimeters; and third, instantaneous road surface water accumulation deeper than 15 centimeters. During last week's heavy rain, we deployed infrared monitoring equipment, but the rain curtain caused the system to misjudge turn signal operations three times, ultimately leading to the suspension of tests across the entire examination center. In fact, the embedded induction magnetic nails in the driving test system also fail when submerged in water. How can the test proceed if the windshield wipers at maximum speed can't even clear the lane lines? Nowadays, exam cancellations are notified via the 12123 APP, so candidates should remember to enable push notifications. Here's a lesser-known fact: the waiting hall always keeps 200 umbrellas ready for rainy days, but we never hesitate to suspend tests when necessary.

Last year when I took the Driving Test Part 3, I encountered an extreme rainstorm. All the test vehicles had their hazard lights on and were parked inside the venue. The DMV directly announced the suspension of the test via broadcast, and staff members went around with registration forms to reschedule the test dates for everyone. Later, the maintenance workers mentioned that the millimeter-wave radar sensors on the test vehicles would report errors when wet, preventing the computer system from even issuing the start command. Actually, you could predict it by observing the placement of flood-prevention sandbags at the exit of the test site—if the sandbags were piled up half a meter high, there was an 80% chance the test would be suspended. My advice is to check the cloud map before heading out. For city-wide rainstorms with purple-red radar echoes, the DMV usually sends suspension notices via SMS two hours in advance.

As a seasoned driver who went through three driving schools before getting my license, it's all too common for exams to be canceled during heavy rain. The key is whether the rain can soak through the reflective vest—visibility below 50 meters means an automatic halt. Last year, while accompanying a relative for their test, we encountered a downpour. The DMV detected four puddles over 12 cm deep on the test route, and the electronic examiner locked the system immediately. Actually, the ABS sensor lines in test cars can short-circuit in water, misjudging braking actions. During storms, the LED screen in the waiting hall displays real-time water accumulation maps of the test site. Here's a tip: Watch for the yellow triangular warning sign at the security booth—if it's up, it means the internal circuit breaker mechanism has been activated.

A mechanic who has been repairing exam vehicles for eight years tells you that during heavy rain, the DMV is more nervous than the test takers. The waterproof rating of the exam vehicle's road test equipment is only IP65. In heavy rain, the GPS antenna can drift over 2 meters, and the hydraulic sensor for the auxiliary brake reports error codes when exposed to water. Last month during maintenance, I found that after heavy rain, the OBD ports of exam vehicles often leak, causing system blue screens. Now, test centers are equipped with laser rain gauges. When heavy rain reaches the orange warning level, the electronic road test system's power is automatically cut off. The TV wall in the waiting hall switches to the meteorological bureau's radar map. If you see purple echoes covering the test center location, don't wait foolishly—rescheduling for next week's makeup exam is more practical.
