The most basic function of the interior rearview mirror is to observe rear passengers, especially children in the back seat. The interior rearview mirror can also be used to judge distance between vehicles, assist in turning, and observe vehicles behind during emergency braking. Specific functions are as follows: 1. Judging distance: Maintaining a proper distance from other vehicles while driving can significantly reduce the occurrence of traffic accidents. However, sometimes the exterior rearview mirrors cannot clearly display the distance of vehicles behind. The interior rearview mirror allows for a clearer judgment, enhancing safety. 2. Turning assistance: When preparing to overtake or change lanes, drivers usually turn on the turn signal first and then observe the vehicles behind through the interior rearview mirror. After assessing the driving conditions of the rear vehicles, they can safely change lanes. 3. Emergency braking: Rear-end collisions are common issues during driving. If the vehicle ahead brakes suddenly, the driver must react promptly. At this time, the interior rearview mirror can be used to observe the vehicles behind and adjust the driving distance based on their movement, effectively avoiding rear-end collisions.

I've found that the most crucial function of the interior rearview mirror is to keep you constantly aware of the situation behind your vehicle. While driving, you don't need to turn your head - just a quick glance lets you know if there's a car following you. It's especially useful for checking safe following distances before changing lanes. Last time I was driving on the highway, it helped me spot a large truck following too closely, allowing me to change lanes and avoid danger. This mirror also assists with reversing - although backup cameras are common now, their images can be distorted, while the rearview mirror provides the most accurate rear view. It's also very practical when children are in the car. My kid sits in a safety seat in the back, and I can constantly monitor his status through the mirror. Remember to keep your rear window clean, avoid obstructing items, and adjust the mirror angle correctly.

Why are some car steering wheels on the right side?

Some cars have steering wheels on the right side due to different traffic rules in their respective countries. Currently, there are two main traffic systems in the world: driving on the right side and driving on the left side. Initially, when Karl Benz invented the car, the steering wheel was positioned in the center. However, based on ergonomic principles, over 90% of people are right-handed. To ensure accurate and safe operation of the gear shift and brakes, designers naturally placed the driver's seat on the right side. Factors determining the position of the car steering wheel: The position of the car steering wheel is determined by the traffic rules of each country and is unrelated to the type of vehicle. Automakers produce and market vehicles accordingly based on the region. If a country or region drives on the left, the steering wheel of the cars sold will be on the right side; if a country or region drives on the right, the steering wheel of the cars sold will be on the left side. Asian countries and regions with the driver's seat on the right: Bangladesh, Bhutan, Brunei, India, Indonesia, Japan, Malaysia, Maldives, Nepal, Pakistan, Singapore, Sri Lanka, Thailand, Hong Kong (China), Macau (China).

What does 'Inspection valid until August 2021' mean?

Below is a detailed introduction about it: Introduction 1: The motor vehicle owner can apply for an inspection compliance label at the vehicle management office of the registration location within three months before the expiration of the motor vehicle inspection validity period. Introduction 2: If a motor vehicle driven on the road does not display a motor vehicle license plate, does not have an inspection compliance label or insurance label, or does not carry the vehicle registration certificate or driver's license, the traffic management department of the public security organ shall detain the motor vehicle and notify the party to provide the corresponding license plate, label, or complete the corresponding procedures.

Is the License Plate Selection Process the Same for Used Cars and New Cars?

License plate selection for used cars follows the same process as for new cars. Below is relevant information about vehicle license plate selection: Selection Modes: Both used car and new car online license plate selections share the same pool of available plates. The system offers vehicle owners two selection modes: 20 attempts at self-composed plate numbers and 5 attempts at random selection. Important Notes for License Plate Selection: The processing time for self-selection and one-time selection is 5 minutes. If no selection is made during the first attempt, another attempt can be made after five minutes. When selecting plates, make full use of the selection rules by preparing three preferred plate numbers in advance and entering them in order on the selection machine. When all three entered plate numbers are already taken, you can use the similar-number query function. The selection system will then provide six similar numbers based on the rules of your first entered number, from which you can make your choice.

What is the appropriate tire pressure for the UY125?

The normal tire pressure range for the Suzuki UY125 is 2.4-2.5 bar. According to the requirements and specifications of the international GBT2978-2008 standard, the standard tire pressure is 2.4-2.5 bar; the reinforced tire pressure is 2.8-2.9 bar; the maximum pressure should not exceed 3.5 bar. Hazards of over-inflated tires: The friction and adhesion of the tires will decrease, affecting braking performance; It can cause steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear on the central tread pattern, shortening tire life; Increases vehicle vibration, indirectly affecting the lifespan of other components; Excessive stretching of tire cords can reduce tire elasticity, increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more easily punctured, and impacts can cause internal cracks or blowouts, leading to tire failure. Hazards of under-inflated tires: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, posing safety risks; Increases movement in various parts of the tire, leading to abnormal heat due to excessive rolling; Reduces the functionality of cords and rubber, causing delamination or cord breakage, and excessive friction with the rim, damaging the bead area and causing abnormal wear; Dramatically increases friction with the ground, rapidly raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may lead to blowouts; Increases tire deformation, making the sidewalls prone to cracking and causing flexing movements, leading to excessive heat, rubber aging, cord fatigue, and breakage. It also increases the tire's contact area with the ground, accelerating shoulder wear.
