How to Turn on the Wiper of an Exam Car?
2 Answers
The wiper of an exam car is operated using the lever on the right side of the steering wheel. The lever has gears, which represent the working frequency of the wiper. Here is some related information about the wiper: 1. The formal name of the wiper is Windshield Wiper: It refers to the blade structure installed in front of the windshield, composed of a motor, reducer, four-bar linkage, wiper arm spindle, wiper blade assembly, etc. Its main function is to clear rain, snow, and dust that obstruct the view on the windshield. 2. There are generally two types of wipers: one is the traditional intermittent type, which is the most common wiper, with three to four segments, adjusted by the driver according to the rain intensity and visibility conditions; the other is the rain-sensing type, mostly used in mid-to-high-end models. A good wiper must have characteristics such as heat resistance, cold resistance, acid and alkali resistance, corrosion resistance, the ability to fit the windshield, reduce the burden on the motor, low noise, strong water repellency, and soft material to avoid scratching the windshield, ensuring clear vision.
I was particularly nervous about operating the windshield wipers during my driving test, but the method is actually quite simple. When sitting in the test car, there is a lever on the right side of the steering wheel, usually next to the turn signal. Gently rotate or pull it downward to activate the wipers. Depending on the intensity of the rain, adjust the speed by turning the switch—for example, one click for slow speed and additional clicks for faster speeds. If it rains during the test, the examiner will usually remind you to turn on the wipers, so stay calm and keep your focus on driving. During practice sessions, familiarize yourself with the lever’s position, as it may vary slightly between car models. Once the wipers are on, maintain clear visibility but avoid letting them distract you during turns or parking. Remember, wiper operation isn’t complicated during the test—the key is not to turn the wrong way or forget to turn them off under pressure. Practice operating the switch a few times beforehand to build muscle memory, and it will become second nature.
