Even experienced drivers sometimes get confused by terminology when it comes to car parts that seem obvious. Mirror located inside the cabin in front of the driver, is one of these elements. It is seen every day, but not everyone knows the correct name, technical features and even legal nuances of use. Meanwhile, this is not just an accessory - it is key security element, on which visibility and driving comfort depend.
In this article we will not only answer the question "What is the name of the mirror in the car in front of the driver", but we will also analyze its structure, types, configuration rules, and even little-known functions that many are unaware of. We’ll also find out why in some countries its absence can cause a fine, and how to choose the right mirror when replacing it.
There is no point in arguing about the importance of this element: according to traffic police statistics, up to 12% road accidents occur due to incorrectly adjusted mirrors or their absence. At the same time, the traffic rules clearly state the requirements for their condition - but more on that later. For now, let's understand the terminology so that the car service center or spare parts store understands you perfectly.
Official name: why not “sun protection” and not “central”
The most common mistake is to call this mirror "sun-protective". In fact, a sun visor in a car refers to a completely different element - a plastic panel above the windshield that protects the driver's eyes from direct sunlight. And the mirror located in front of the driver has a strict technical name:
Interior rear view mirror (or interior rearview mirror) is its official designation in Traffic regulations, technical documentation of cars and spare parts catalogues. In colloquial speech the following options are also used:
- 🔄 Central mirror — due to the location in the center of the cabin;
- 🚗 Driver's mirror — because it is driver-oriented;
- 🔍 Rearview mirror - emphasizes its main function.
Interestingly, in English it is called rear-view mirror (literally - “rear view mirror”), and in German - Innenspiegel ("internal mirror"). These terms are often found in instructions for foreign cars, so it is useful to know them.
Why is it so important to use the correct name? The fact is that when ordering spare parts or contacting service, inaccurate wording can lead to confusion. For example, the phrase "I need a mirror above the windshield" may be interpreted as a request to replace the sun visor and not the interior mirror.
Design and principles of operation: what is hidden behind simple glass
At first glance, the interior rearview mirror is just a piece of glass in a plastic frame. But in fact its design is dictated reflection physics, ergonomics and safety requirements. Let's figure out how it works and why not all mirrors are the same.
Main components:
- 🔲 Reflective surface - can be flat or spherical (read about the differences below);
- 🖼️ Frame — attached to the windshield or ceiling of the cabin, often contains fastening elements;
- 🔧 Adjustment mechanism — allows you to change the angle of inclination (manually or electrically);
- 💡 Additional items — light sensors, indicators, backlight (in premium models).
The most important parameter is radius of curvature of the reflecting surface. There are three types of mirrors:
- Flat — give the most accurate picture, but limit the viewing angle (standard for most passenger cars);
- Spherical (convex) — increase the viewing angle, but distort the distance to objects (more often used in trucks and buses);
- Aspherical - combined, with different curvatures along the edges (found in premium cars).
In most modern cars, flat mirrors are installed, as they correspond GOST R 41.46-2005 (analogous to the European standard ECE R46), which regulates the minimum viewing angle - no less 20° horizontal and 5° vertical. This means that the mirror must show at least 20 meters of space behind the car in a standard driving position.
Why do trucks use convex mirrors?
In trucks and buses, the interior rear view mirror is often made spherical (convex), because it increases the viewing angle to 40-50°. This is critical for large vehicles, where “blind spots” can hide entire passenger cars. However, such mirrors distort distance - objects appear further away than they actually are. Therefore, truck drivers have to learn to judge distances through experience.
Another nuance is anti-reflective coating. Cheap mirrors do not have it, which is why in the dark the headlights of cars driving behind blind the driver. High-quality mirrors have a special coating that reduces glare by 60-80%.
Functions of the interior mirror: not only to look back
The main task of the interior mirror is to provide an overview of the space behind the car. But in fact, its functions are much broader, and some of them may surprise even experienced drivers.
Main functions:
- 👀 Monitoring the situation from behind — assessment of the distance to other cars, pedestrians, obstacles;
- 🚦 Maneuver assistance — parking, changing lanes, reversing;
- 💡 Indication — some models have light sensors, turn signals or displays built into the mirror;
- 🔄 Lighting adjustment — automatic mirrors darken when the headlights are bright from behind;
- 🚨 Security — helps to notice the approach of special transport (ambulance, police).
But there is also hidden possibilities, which not everyone knows about:
- 🔍 Interior monitoring — through the mirror it is convenient to observe passengers in the back seat (relevant for taxi drivers or parents);
- 📱 Gadget mount — some mirrors have holders for smartphones or recorders;
- 🔋 Hidden socket — in premium cars, the mirror frame may have a USB port or connector for connecting accessories.
Interesting fact: in some countries (for example, Japan), the interior rear view mirror must have wide angle zone (usually marked with a line). This helps drivers better monitor their blind spots when driving in heavy traffic.
If your car does not have an automatic dimming mirror, you can buy a polarizer sticker (costs about 300-500 rubles). It adheres to an existing mirror and reduces glare from rear headlights by 70%.
And a salon mirror can also become fault indicator. For example, if it starts to tremble on bumps, this may indicate:
- Loosening of the fastening to the windshield;
- Wear of shock absorbers (if vibration is transmitted to the body);
- Suspension problems (in rare cases).
Traffic rules and GOST requirements: what happens if there is no mirror or it is broken
Many drivers don't know that missing or faulty interior rear view mirror may result in a fine. In Russia, this is regulated by two documents:
- Traffic rules, paragraph 4.1 — prohibits the operation of the vehicle if the devices providing visibility are not working;
- GOST R 51709-2001 — establishes requirements for rear-view mirrors, including interior mirrors.
According to these standards:
- 🚫 Prohibited drive without an interior mirror, if it is provided for by the design of the car;
- 🔧 The mirror must be intact — cracks, chips or peeling of the reflective layer are considered a malfunction;
- 🔄 It must be regulated - if the mechanism is broken and the mirror does not lock in the desired position, this is a violation;
- 💡 No glare allowed - if the mirror blinds the driver, this is equivalent to a malfunction.
In practice, traffic police inspectors rarely stop a car just because of a problem with the interior mirror. However, if you are stopped for another reason and a malfunction is discovered, you may be fined Part 1 of Article 12.5 of the Code of Administrative Offenses — "Driving a vehicle in the presence of malfunctions". Fine amount:
| Violation | Fine (rub.) | Additional measures |
|---|---|---|
| The interior mirror is missing | 500 | Warning or fine |
| Mirror is broken/not adjustable | 500 | A removal order may be issued. |
| The mirror blinds the driver (there is no anti-reflective coating) | 500 | Recommendation to replace or repair |
| The mirror is covered with foreign objects (for example, a keychain hanging) | 500 | Requirement to remove interference |
In addition, if the interior mirror is missing or faulty, this may cause refusal to undergo technical inspection. According to the maintenance regulations, the presence and functionality of all mirrors provided for by the car’s design are checked.
⚠️ Attention: If you have a car with tinted windows (light transmission less than 70%), the absence or malfunction of an interior mirror can be regarded as a deliberate impairment of visibility. In this case, the fine may be increased to 1,500 rubles.
How to properly adjust a mirror: step-by-step instructions
Even the best quality mirror is useless if it is not adjusted correctly. According to statistics, up to 30% of drivers They drive with incorrectly adjusted mirrors, which increases the risk of an accident. Let's look at how to configure the interior rear view mirror as efficiently as possible.
Step by step instructions:
- Take your normal driving position - adjust the seat, steering wheel and seat belts;
- Look in the interior mirror: you should see the entire rear window of the car without distortion;
- Adjust the tilt of the mirror so that the top reflects the horizon (the line where the sky meets the ground) and the bottom reflects the back seat;
- Check that the mirror does not reflect interior elements (for example, a rear parcel shelf) that may interfere with your view;
- Make sure you can see at least 20% of the side of the car in your mirror (this will help monitor your blind spots).
For clarity, correct and incorrect settings:
| Parameter | Correct | Wrong |
|---|---|---|
| Rear window visibility | Completely, without cuttings | Partially, from the edges |
| Horizon | A straight line in the upper third of the mirror | Tilt or not visible |
| Side zones | Part of the rear wings is visible | Only a straight line behind the car |
| Glare | None or minimal | They blind the driver |
If your car has a mirror with automatic dimming, check its operation:
- Turn on the ignition;
- Point a bright light (such as a flashlight) at the mirror;
- It should darken within 1-2 seconds.
⚠️ Attention: If, after adjusting the mirror, you still cannot see part of the space behind, check whether your view is not obstructed:
- High rear headrests;
- Bulky child seats;
- Foreign objects on the rear shelf (for example, boxes).
In such cases it may be necessary additional mirror with wide viewing angle.
☑️ Checking the correct mirror adjustment
How to choose a mirror when replacing: what to look for
If the interior mirror is broken, tarnished or no longer adjustable, it needs to be replaced. But how to choose the right model among hundreds of options in stores? Here are the key parameters to pay attention to.
1. Mounting type
Mirrors are attached to the car in two ways:
- 🔗 On the button (to the windshield) - the most common option. The button is glued to the glass, and the mirror is put on it;
- 🔩 On a bracket (to the cabin ceiling) - found in some models Toyota, Honda and premium cars.
Before purchasing, check what type of mount your machine uses. If the button is broken, it can be replaced separately (costs 100-300 rubles).
2. Size and shape
Standard sizes of interior mirrors:
- 📏 Length: 10-15 cm (for passenger cars), 15-20 cm (for SUVs and minibuses);
- 🔺 Shape: rectangular, oval or trapezoidal (depending on the car model).
If you want a mirror with increased view, look for models marked "panoramic" or "wide-angle". They are 20-30% wider than standard ones.
3. Type of reflective surface
| Type | Pros | Cons | Price (RUB) |
|---|---|---|---|
| Standard (flat) | Accurate distance transmission, low price | Narrow viewing angle | 300-800 |
| Anti-glare | Doesn't dazzle in the dark | The price is higher, the colors may be slightly distorted | 800-1 500 |
| Automatic (with dimming) | Self-adjusts brightness, premium quality | Expensive, requires electrical connection | 2 000-5 000 |
| Spherical (convex) | Wide viewing angle | Distorts the distance to objects | 1 000-2 000 |
4. Additional features
Modern mirrors can have built-in:
- 📹 Rear view camera — transmits the image to the radio screen;
- 🔋 USB port or wireless charging — for connecting gadgets;
- 🚨 Light/rain sensor — automatically turns on the headlights or wipers;
- 📱 Smartphone holder — convenient for navigation.
If you choose a mirror with electronic functions, make sure it is compatible with your car model. For example, mirrors with a rear view camera may require a special connection to the on-board computer.
⚠️ Attention: When purchasing a heated or auto-dimming mirror, check whether your car has the appropriate connectors for connection. Otherwise, you will have to do the wiring yourself, which may void the warranty.
If you are not sure about the choice, take the old mirror with you to the store or take a photo of its mount. This will help the seller find the exact replacement.
Common problems and their solutions: from shaking to fogging
The interior mirror, despite its simple design, can cause a lot of trouble. Let's look at the most common problems and how to fix them.
1. The mirror shakes when moving
Causes and solutions:
- 🔧 The fastening of the button to the glass is loose - glue it with special glue (for example, 3M VHB);
- 🚗 Body vibration — check the shock absorbers and suspension;
- 🔄 Wear of the adjustment mechanism - Replace the mirror or lubricate the hinges.
2. Constantly fogs up
This is true for mirrors glued to the windshield. Solutions:
- 💨 Improve interior ventilation — check the operation of the stove and air conditioner;
- 🧴 Apply anti-fog agent (for example, Sonax or Liqui Moly);
- 🔥 Install heated mirrors (there are models with a built-in heating element).
3. Glare from headlights from behind
If the mirror does not have an anti-reflective coating, you can:
- 🔲 Apply polarizing film (costs 200-500 rubles);
- 🔄 Adjust the tilt angle — slightly lift the mirror up;
- 💡 Replace with an auto-dimming mirror.
4. The reflective layer is cracked or chipped
In this case, the mirror must be replaced. Workaround:
- 📄 Seal the crack with clear tape (so that the fragments do not fly apart);
- 🔧 Use outside mirrors before replacement (but this is unsafe).
5. Not adjustable (mechanism jammed)
Try:
- 🛠️ Lubricate the hinges with silicone grease;
- 🔧 Disassemble and clean the mechanism (if the mirror is collapsible);
- 🆕 Replace with new one (if repair is not possible).
If the mirror electric and is no longer regulated, check:
- 🔌 fuse (usually it is shared with other electrical accessories);
- 🔋 Wiring — the contact may have come loose;
- 📱 Control button — it could stick or break.
If the mirror falls off along with the button, do not try to glue it with superglue - it will not withstand vibrations. Use a special polyurethane-based automotive adhesive (for example, 3M Scotch-Weld).

FAQ: answers to frequently asked questions
🔍 Is it possible to drive without a rear view mirror?
Technically it is possible, but this is a violation of traffic rules (part 1 of article 12.5 of the Administrative Code). Fine - 500 rubles. In addition, without an interior mirror, visibility is greatly impaired, which increases the risk of an accident. An exception is cars in which the interior mirror is not provided by design (for example, some sports cars or vintage cars).
💡 Why is the mirror glued to the ceiling in some cars and not to the glass?
It depends on the design of the car. Mirrors on the ceiling (on a bracket) are more often found in:
- SUVs and crossovers (for example, Toyota Land Cruiser, Nissan Patrol);
- Minibuses and commercial vehicles;
- Some premium sedans (for example, Mercedes S-Class).
This type of fastening is considered more reliable, since it does not depend on the strength of the windshield.
🔧 How to remove a mirror without damaging the windshield?
Carefully pry up the plastic plug at the base of the mirror (usually it is held on by latches). Below it you will see a screw or fastening button. If the mirror is on the button:
- Pull the mirror toward you with force;
- The button should remain on the glass - it can be peeled off by heating it with a hairdryer (temperature 50-60°C);
