Side Mirrors? The Driving Debate That Has Everyone Questioning Their Habits
For years, I genuinely believed that you were supposed to see a little bit of your own car in your side mirrors.
It always made sense to me. Seeing the edge of my vehicle gave me a familiar reference point and helped me understand where my car was in relation to everything around me. Whether I was changing lanes, parking, or driving on a busy road, that small glimpse of my own car made me feel more confident behind the wheel.
I never questioned it. I assumed that was simply how side mirrors were supposed to be adjusted.
Then someone told me something that completely changed the way I thought about it.
Apparently, according to many driving experts, you should adjust your side mirrors so that you can barely see, or cannot see at all, the side of your own vehicle when sitting in your normal driving position.
The reasoning was surprisingly simple: why waste part of your mirror looking at your own car when that space could be used to see other vehicles?
At first, I thought it sounded a little strange. Surely, seeing part of your own car helps you judge distances and understand where you are on the road?
But the more I thought about it, the more I realized that I had never actually researched the subject. I had simply adjusted my mirrors the same way for years and assumed there was nothing wrong with it.
And apparently, this is one of those driving topics that can spark a surprisingly passionate debate.
Some drivers insist that seeing a small portion of their vehicle is essential. Others argue that keeping the car out of the mirror's view can improve visibility and help reduce blind spots.
Both sides seem convinced that their method is the right one.
So, what does the evidence actually say? Is seeing your own car in the side mirrors a useful safety feature, or could it be limiting your view of the road?
The answer comes down to understanding what your mirrors are designed to do.
Why Drivers Traditionally Keep Their Cars Visible in the Mirrors
If you learned to drive years ago, there is a good chance you were taught to adjust your side mirrors so that a small portion of your own vehicle remained visible.
For many people, this approach feels completely natural.
When you can see the edge of your car, you have a fixed visual reference that helps you understand what you are looking at. It can make it easier to judge the position of nearby vehicles, recognize the boundaries of your own vehicle, and estimate how much space you have when maneuvering.
Think about reversing into a parking space, for example.
You might use your side mirrors to check how close you are to a curb, a parking line, or another vehicle. Seeing the side of your car can help you estimate the distance between your vehicle and the obstacle.
The same principle applies when driving through a narrow street or squeezing into a tight parking space.
That small section of visible bodywork can provide reassurance, particularly for drivers who are not completely comfortable judging the dimensions of their vehicles.
There is also a psychological element.
Driving requires you to process a tremendous amount of information at once. You need to watch the road ahead, monitor surrounding traffic, observe road signs, maintain a safe distance, and anticipate the actions of other drivers.
Having a familiar reference point can make some of these tasks feel easier.
For someone who has driven with mirrors adjusted this way for twenty years, changing them can feel uncomfortable. The mirror suddenly looks different, and the driver may feel as though something important is missing.
However, feeling comfortable with a mirror position does not automatically mean it provides the best possible view of surrounding traffic.
That is where the debate begins.
Why Some Experts Recommend Angling Mirrors Outward
The alternative approach is to adjust your side mirrors farther outward so that you can see more of the lanes beside your vehicle.
This method is often called the blind-zone or blind-spot mirror adjustment technique.
The principle is straightforward: your own vehicle is already visible through your windshield and side windows. You can also turn your head to check its position relative to nearby objects.
The surrounding traffic, however, requires more attention.
A vehicle approaching from behind can move out of the interior rearview mirror's field of view and into an area beside your car that is not adequately covered by your side mirrors.
If your side mirrors are aimed too far inward, they may show a substantial portion of your own vehicle while duplicating some of the view already provided by the interior mirror.
Angling them outward can reduce this overlap and help you see more of the adjacent lanes.
Imagine driving on a highway when another car approaches from behind in the lane next to yours.
With poorly adjusted mirrors, the vehicle might disappear from your interior rearview mirror before becoming visible in your side mirror. During that brief moment, you may not know exactly where it is.
By adjusting your side mirrors outward, you may reduce that gap and improve your awareness of approaching traffic.
This does not eliminate every blind spot, and it does not mean that every outward adjustment is automatically correct.
The goal is to improve the overall coverage provided by your mirrors.
In other words, the important question is not whether you can see your own car. It is whether your mirrors provide a useful view of the traffic around you.
How to Adjust Your Side Mirrors Correctly
If you have always used the traditional method, trying a different setup can be worthwhile.
Start while your vehicle is parked safely, with the seat adjusted to your normal driving position.
Step 1: Adjust the interior rearview mirror
Your interior mirror should provide a clear view through the rear windshield.
Position it so that you can see as much of the area directly behind your vehicle as possible without needing to move your head significantly.
This mirror is your main reference for traffic approaching from directly behind.
Step 2: Adjust the driver's side mirror
A commonly taught starting technique is to lean your head toward the driver's side window until it is close to the glass.
From that position, adjust the mirror until you can just see the side of your car along its inner edge.
When you return to your normal sitting position, the side of your vehicle should be barely visible or may disappear from view.
This helps direct the mirror toward the adjacent lane instead of toward your own car.
Step 3: Adjust the passenger-side mirror
For the passenger-side mirror, lean your head toward the center of the vehicle.
Adjust the mirror until you can just see the side of your car along the inner edge.
When you return to your normal driving position, your vehicle should be barely visible or not visible at all.
These positions are useful starting points, but they are not universal rules. Vehicle dimensions, mirror shapes, and seating positions differ.
Always check that the resulting view is useful for your particular vehicle.
Step 4: Check the coverage
Once all three mirrors are adjusted, observe how traffic appears in them.
The interior mirror should show the area behind you, while the side mirrors should extend your view toward the adjacent lanes.
Ideally, vehicles moving from behind toward the side of your car should transition between the mirror views with minimal gaps.
You can check your mirror coverage while parked by observing stationary objects or asking someone to walk around the outside of your vehicle.
Never rely on this check as proof that every blind spot has disappeared.
Even properly adjusted mirrors leave areas that may require a direct visual check.
Does Seeing Your Own Car Actually Make Driving Less Safe?
Not necessarily.
Seeing a small portion of your vehicle does not automatically make your mirrors dangerous or mean that you have been driving incorrectly for years.
The real issue is how much of the mirror's viewing area is occupied by your car and what remains visible around it.
If a large section of your mirror shows your own vehicle, less of that mirror is available to show surrounding traffic.
Depending on the mirror's position and your vehicle's design, that may leave some adjacent areas harder to see.
Consider a vehicle approaching in the next lane.
As it moves forward, it may leave the area covered by your interior mirror. If your side mirror is aimed too far inward, the approaching vehicle might not yet appear there.
This creates a gap in your mirror coverage.
A more outward-facing mirror can help reduce that gap by showing more of the neighboring lane.
However, the size and location of blind spots vary between vehicles. Some cars have wide fields of view, while others have large areas hidden by bodywork, pillars, or mirror limitations.
That is why simply removing your car from the mirror is not enough.
A mirror can show no part of your vehicle and still be adjusted poorly if it fails to cover the area you need to monitor.
The goal should always be better visibility, not following a rule for the sake of it.
Why Many Experienced Drivers Prefer the Traditional Method
If outward-adjusted mirrors can improve coverage, why do so many experienced drivers continue to keep their cars visible?
One reason is habit.
Most people learned to drive from instructors, parents, or relatives who taught them a particular way of adjusting mirrors. Once that method becomes familiar, there is little motivation to change it unless someone explains the benefits of an alternative.
Another reason is that seeing your vehicle can be useful for certain maneuvers.
When parking, reversing, or driving through a narrow space, a view of the side of your car may help you judge its position.
But the best mirror position for parking is not necessarily the best position for monitoring fast-moving traffic.
These tasks have different requirements.
For everyday driving, you generally want your mirrors to provide a broad and useful view of the road around you.
For parking, you may benefit from additional visual references, a temporary mirror adjustment where appropriate, or a camera system if your vehicle has one.
You do not have to assume that one mirror setting is perfect for every situation.
What matters is understanding what you can see, what you cannot see, and when you need to look directly.
What About Blind-Spot Monitoring Systems?
Many modern vehicles have blind-spot monitoring systems that use sensors to detect vehicles in areas beside or behind the car.
Depending on the vehicle, these systems may provide a warning light in the side mirror or an audible alert when another vehicle is detected.
They can be useful, particularly when driving on busy highways or when traffic approaches quickly from behind.
However, these systems should be treated as additional safety aids rather than replacements for correctly adjusted mirrors.
Their performance varies by manufacturer and operating conditions. They may not detect every road user or obstacle in every situation.
If your car has this feature, check the owner's manual to understand its capabilities and limitations.
Regardless of the technology installed, you should remain attentive to your surroundings and check your blind spots before changing lanes.
Technology can support safe driving, but it should never encourage you to stop looking.
The Shoulder Check Still Matters
Here is something that should not get lost in the debate about mirror positioning: even perfectly adjusted mirrors cannot guarantee that you will see everything around your vehicle.
That is why checking your blind spot remains important.
Before changing lanes, look in the relevant mirror and briefly turn your head toward the lane you intend to enter to check the area that may not be visible in your mirrors.
This helps you identify vehicles, motorcycles, or other road users that might otherwise go unnoticed.
Keep the check brief and deliberate so that you do not lose awareness of the road ahead.
A sensible routine includes checking surrounding traffic, looking in your mirror, signaling, checking the blind spot, and moving only when it is safe and permitted.
Always follow local traffic laws and your driving instructor's guidance.
No mirror adjustment makes it safe to change lanes without checking your surroundings.
Is There One Correct Mirror Position for Everyone?
Not exactly.
Different vehicles have different shapes, mirror designs, and seating positions.
A compact car, a pickup truck, and a large SUV may provide very different views of the surrounding road.
Some vehicles also have convex side mirrors, which show a wider area but make objects appear smaller or farther away than they actually are.
Drivers need to understand these differences and become familiar with the view provided by their particular vehicle.
If you try a new mirror position, make the adjustments while parked and learn how traffic appears in the mirrors before relying on them in demanding driving conditions.
If you find it difficult to see nearby traffic clearly, a qualified driving instructor can help you find an appropriate setup.
The objective is not to follow a rule blindly. It is to make sure you can monitor the road effectively.
So, Should You See the Side of Your Car in Your Mirrors?
After considering both approaches, I can understand why this debate continues.
For drivers who have spent years seeing a little bit of their own car, that familiar reference point can feel reassuring.
It can help with parking and provide a visual indication of where the vehicle is positioned.
However, when it comes to monitoring surrounding traffic, adjusting the side mirrors farther outward can reduce unnecessary overlap and improve the view of adjacent lanes.
That does not mean every driver who sees part of their car is doing something wrong.
Nor does it mean that making your vehicle disappear from the mirror guarantees the best possible adjustment.
The result matters more than the appearance of the mirror.
You want a clear, useful view of traffic beside and behind your vehicle, combined with an effective view of the road directly behind you.
You also need to understand the limitations of your mirrors and perform appropriate blind-spot checks before changing lanes.
For many drivers, the biggest lesson is simply that something can feel normal because we have been doing it for years, even when there may be a better way.
If you have always adjusted your mirrors to show the side of your car, consider reviewing your setup.
Make any changes carefully, become familiar with the new view, and never assume that a mirror adjustment eliminates the need to check your surroundings.
What Do Most Drivers Actually Do?
Ask a group of drivers how they adjust their side mirrors, and you will probably hear several different answers.
Some deliberately keep a small portion of their vehicle visible. Others angle their mirrors outward to see more of the surrounding traffic. Many simply follow whatever method they learned when they first started driving.
Without reliable survey data, it would be misleading to claim that one approach is used by the majority of drivers.
What matters more than popularity is whether your mirrors provide an adequate view of the areas around your vehicle.
Mirror adjustment should be based on visibility and safety rather than familiarity alone.
This is also an important lesson for new drivers. Learning to adjust mirrors properly from the beginning can help them develop good habits before becoming attached to a particular setup.
A few minutes spent checking your mirrors can make a meaningful difference in how well you understand your vehicle's surroundings.
The Bottom Line
If you can see a little bit of your own car in your side mirrors, there is no need to panic or assume you have been driving dangerously for years.
However, reviewing your mirror setup is worthwhile.
Consider adjusting your mirrors so they show more of the lanes beside your vehicle and less of the car itself, while maintaining a useful view of traffic behind you.
Check the results for your particular vehicle, learn where the remaining blind spots are, and continue performing appropriate shoulder checks before changing lanes.
Remember that mirror adjustment is only one part of safe driving. Maintaining a safe following distance, signaling properly, staying attentive, and anticipating the actions of other drivers are equally important.
The next time you get into your car, take a moment to look at your mirrors.
Are they showing you the traffic you need to see, or are they showing you a large part of a vehicle you already know is there?
That simple question might help you discover a better way to set them.
Now I'm curious: How have you adjusted your side mirrors all these years?
Do you prefer seeing a little bit of your own car because it helps you judge distances, or do you angle your mirrors outward so you can see more of the surrounding traffic?
Have you ever changed your mirror settings after learning about blind-spot reduction?
