Rear view mirrors are not just an accessory, but key security element on the road. According to traffic police statistics, more 30% accidents occur due to improper monitoring of the situation through mirrors or ignoring blind spots. Many drivers, even with many years of experience, make a critical mistake: looking in the mirrors too late or not at that momentwhen it's really necessary. For example, when changing lanes in heavy traffic, a half-second delay is enough to not notice a motorcyclist approaching at a speed of 100+ km/h.
In this article we will look at physiological and technical aspects working with mirrors - from proper settings to the psychology of perception. You'll find out why central mirror should not show the rear window, but the road, how to use peripheral vision to monitor blind spots, and why professional racers look in their mirrors otherwisethan ordinary drivers. Spoiler: it's all about viewing angle and reaction speed.
Next - specific instructions, tables of viewing angles and answers to questions that you were embarrassed to ask the instructor at the driving school.
1. Physiology of vision: why we donβt notice cars in mirrors
The human eye is designed in such a way that central vision (responsible for clarity) covers everything 2Β° viewing angle, and peripheral - up to 180Β°. However, the brain automatically ignores static objects in the periphery, focusing on movement. That is why the driver can not notice a car that has been driving parallel for a long time in the adjacent lane, but will instantly react to a motorcycle that suddenly appears in the mirror.
Research MIT showed that at speed 60 km/h the driver spends on checking the mirrors just 0.3 seconds - this is not enough to estimate the distance to the object. Key problem: the eye focuses on the reflection rather than the actual distance. For example, in a convex side mirror Toyota Corolla a car at a distance of 10 meters seems further than it actually is.
How to fix this?
- Train dynamic vision: Every 5-8 seconds, look from the road to the mirrors and back.
- Use two second rule: if the object in the mirror has not changed position in 2 seconds, it is moving parallel to you.
- Adjust your mirrors so that they covered blind spots, and did not duplicate the review.
2. Setting up mirrors: step-by-step instructions for any car
The mistake 90% of drivers make is adjusting their mirrors for yourself, not under car geometry. Correct setup should exclude blind spots (areas not visible either in mirrors or peripherally). To do this use touch method:
Central mirror:
- Sit in the driver's seat in a normal position.
- Adjust the mirror so that you can see entire rear window from edge to edge.
- Tilt the mirror upto see the top of the rear window - this will help when parking.
Side mirrors:
- πΉ Left mirror: tilt your body outward until you can no longer see the side of your car. Ideally, it should be visible in the mirror horizon line and a small section of the road behind.
- πΉ Right mirror: the same thing, but taking into account the fact that it is usually convex (distorts the distance). Set it up so you can see lane on the right and part of your car.
Critical error: If you can see your car's door handle in the side mirror, you have a blind spot the size of a truck!

3. Mirror βscanningβ technique: when and how to look
Professional drivers (such as taxi drivers or race car drivers) use cyclic inspection of mirrors according to the scheme: road β left mirror β center mirror β right mirror β road. This cycle takes 1β1.5 seconds and repeats every 5β8 seconds. Important: don't fix your gaze on the mirror for more than 0.5 seconds - this distracts from the road ahead.
When necessarily look in the mirrors:
- π¦ Before any braking (even light ones).
- π When rebuilding (first the mirror, then the turn signal!).
- π Before overtaking or ahead of schedule.
- π ΏοΈ When parking lot (especially in reverse).
- π On traffic lights and intersections (Motorcycles and cyclists like to "slip" around edges).
β οΈ Attention: If you are driving on a multi-lane road and see in your mirror a car that does not change position relative to you, it moves at the same speed. This is dangerous when changing lanes: the driver may not expect your maneuver!
| Situation | Which mirror to look at | What to look for |
|---|---|---|
| Change lane to the left | Left β center | Cars in the next lane and behind |
| Overtaking | Center β left β right | Oncoming traffic and cars behind |
| Reverse parking | Central + head rotation | Pedestrians, poles, curbs |
| Driving in heavy traffic | All mirrors one by one | Motorcycles, bicycles, hard brakes |
4. Blind spots: how to detect and neutralize them
A blind spot is an area right and left-back car which not visible neither in mirrors nor peripherally. Its size depends on:
- π Body type (y hatchbacks blind spot smaller than SUVs).
- πͺ Mirror shapes (flat ones give less distortion than convex ones).
- π¨ Driver height (short drivers have large blind spots).
To check your blind spot:
- Park on an empty road.
- Have a helper stand behind the vehicle and slowly move to the side.
- Note the moment when the assistant disappears from the mirror, but is not yet visible peripherally.
How to reduce your blind spot:
- π Use additional mirrors (for example, "fish eye" to the standard side).
- πΉ Install rear view camera with a viewing angle of 170Β°+.
- π Turn your head at 90Β° before changing lanes (yes, itβs inconvenient, but it saves you from an accident).
The Myth of the "Full View"
Many people think that convex mirrors give a "full view", but in reality they distort the distance. For example, a car in such a mirror may appear 2 times further away than it actually is. This is dangerous when parking or overtaking.
5. Features of mirrors in different types of cars
Each body type has its own review nuances:
- π Sedans: The blind spot is minimal, but the rear window is often darkened (problems with visibility at night).
- π Hatchbacks: A short rear overhang improves visibility, but a tall trunk can block the view.
- ποΈ SUVs: Large blind spot due to high body. Recommended additional mirrors on the hood.
- π Trucks and vans: View limited by dimensions. Drivers use system of 3β5 mirrors.
For example, in Volkswagen Tiguan the blind spot on the right is ~2.5 meters (the width of the motorcycle!), and in Lada Granta - total 1.2 meters. In trucks Scania drivers look in their mirrors every 3 seconds due to limited visibility.
β οΈ Attention: In cars with tinted windows (light transmission less than 70%) at night the mirrors become practically useless. In this case, they only help head turn or rear view camera.
If you have a tall car (eg. Kia Sorento), stick small convex mirrors on the side windows. They cost ~500 rubles, but reduce the blind spot by 40%.
6. Common driver mistakes (and how to avoid them)
Even experienced drivers allow critical errors when working with mirrors. Here are the most common:
Mistake 1: Looking in the mirrors only before a maneuver
Correct: constantly scan the situation. A motorcycle or cyclist can appear in your blind spot in a split second.
Mistake 2: Completely trust parking sensors
Sensors don't see low obstacles (curbs) or moving objects (children, animals). Always check your mirrors!
Mistake 3: Not taking into account distortions in convex mirrors
B Hyundai Solaris the right mirror is convex - a car at a distance of 5 meters will appear 2 times further.
Mistake 4: Forgetting about the βdead zoneβ in front
Yes, she is! When turning right (at an intersection, for example), you may not see a cyclist riding parallel to the hood.
Mistake 5: Adjusting mirrors for βconvenienceβ rather than safety
If your door handle is visible in the side mirror, you have giant blind spot.
Professional drivers (taxi drivers, truck drivers) look in their mirrors every 3-5 seconds, even if they are not planning a maneuver. This is called "passive situational awareness" and reduces the risk of accidents by 40%.
7. Mirrors vs. cameras: which is better for security?
Modern cars (eg. Tesla Model 3 or Audi e-tron) replace mirrors with cameras with displays. Benefits:
- πΊ Wide viewing angle (up to 180Β° versus 30Β° for conventional mirrors).
- π No blind spots (cameras show everything that happens from behind).
- π§οΈ Work in any weather (as opposed to foggy or icy mirrors).
But there are also disadvantages:
- β‘ Electronics addiction (when the battery is low, the cameras will turn off).
- π Image delay (even 0.1 seconds can be critical when overtaking).
- π° High cost (replacing a camera costs 5β10 times more than a mirror).
Conclusion: cameras complement mirrors, but do not replace them completely. The best option is hybrid system (mirrors + cameras), as in Mercedes-Benz S-Class.
FAQ: Answers to frequently asked questions
β Why do the side mirrors say βObjects in mirror are closer than they appearβ?
This inscription is on everyone convex mirrors (usually on the right). She warns that due to the curvature of the surface, objects appear furtherthan it actually is. For example, a car that is actually 10 meters away may appear to be 15β20 meters away. This is important to consider when parking or changing lanes.
β How to look in the mirrors correctly when reversing?
Algorithm:
- First look in central mirrorto assess the general situation.
- Turn your head right (to check the right blind spot).
- Use left mirror to control the trajectory.
- Alternate your gaze between the mirrors and turning your head (especially when parking between cars).
Important: Don't rely on the rear view camera alone - it doesn't show objects to the sides!
β Is it possible to drive if the side mirror has fallen off?
By Traffic regulations of the Russian Federation (clause 7.3 of the List of faults), lack of at least one side mirror prohibited. Fine - 500 rubles (Article 12.5 of the Administrative Code). Temporary solution: attach the mirror to a suction cup (sold in any auto store for 300β500 rubles).
β Why do professional racers rarely look in the mirrors?
In motorsports (e.g. Formula 1) riders look in the mirrors only before braking or overtaking. Reason: At high speeds (200+ km/h), even a split second spent looking in the mirror can cost you a position. Instead they rely on:
- π» Radio communication with the team (they are informed about the cars behind).
- π Peripheral vision (trained for years).
- π Telemetry (some cars have a display with radar in the cabin).
But on ordinary roads this approach unacceptable β mirrors are vital here!
β How to train yourself to look in the mirror more often?
Psychological trick: attach bright sticker on the mirror (for example, a red circle). Every time your gaze falls on her, automatically examine the situation. After 2-3 weeks, the habit will form. Another way: turn on metronome (app on your phone) with an interval of 5 seconds - each signal should remind you to check the mirrors.
