Eliminate Blind Spots: The Ultimate Guide to Setting Your Rear-View Mirrors

Blind spots are a persistent danger for drivers, contributing to countless accidents every year. While many drivers rely on a quick glance over their shoulder, this method isn’t always sufficient and can be risky, especially at high speeds or in heavy traffic. The good news is that you can significantly reduce, and even eliminate, blind spots by properly adjusting your car’s rear-view mirrors. This comprehensive guide provides a step-by-step approach to setting your mirrors for optimal visibility, enhancing your safety and confidence on the road.

Understanding the Problem: What are Blind Spots?

A blind spot is an area around your vehicle that cannot be seen in your rear-view mirrors. These areas typically exist on either side of your car, slightly behind you. Cars in these blind spots can be difficult or impossible to see with a quick glance in your mirrors, leading to potentially dangerous situations when changing lanes or merging onto a highway.

Traditional mirror settings often overlap with what you can already see in your central rear-view mirror, failing to provide adequate coverage of the critical areas to your sides. This overlap creates a false sense of security, as drivers may assume that if a car isn’t visible in the central mirror, it must be clear to change lanes. However, this is often not the case.

The Solution: The Society of Automotive Engineers (SAE) Method

The Society of Automotive Engineers (SAE) recommends a method for adjusting your side mirrors that minimizes overlap with the central rear-view mirror and maximizes visibility of adjacent lanes. This method, often referred to as the “wide-angle” or “outward” setting, requires a slightly different approach than what many drivers are accustomed to. While it may feel strange at first, with practice, you’ll find it provides a much clearer and safer view of your surroundings.

Step-by-Step Guide to Eliminating Blind Spots

Follow these steps carefully to properly adjust your rear-view mirrors and eliminate blind spots:

1. Prepare Your Vehicle

• Park on a level surface: Ensure your car is parked on a flat surface to provide an accurate perspective when adjusting your mirrors.
• Adjust your seat: Before adjusting your mirrors, ensure your driver’s seat is properly positioned for comfortable driving. Adjust the seat height, distance from the steering wheel, and backrest angle to your liking. Your mirror adjustments should be based on your typical driving position.

2. Adjust Your Central Rear-View Mirror

• Center the view: Adjust the central rear-view mirror so that you have a clear and unobstructed view directly behind your vehicle. You should be able to see the entire rear window within the mirror’s frame.
• Night mode (if applicable): If your mirror has a night mode lever or button, familiarize yourself with its operation. This feature dims the headlights of vehicles behind you, reducing glare and improving visibility at night.

3. Adjust Your Driver-Side Mirror (Left Mirror)

• Lean to the right: Lean your head towards the center of your car, almost touching the center console. This shifts your perspective and allows you to set the mirror further outward.
• Adjust the mirror: While maintaining this leaned position, adjust the driver-side mirror until you can barely see the side of your car in the innermost edge of the mirror. The goal is to minimize the overlap with the central rear-view mirror’s field of view. You should primarily see the lane next to you and the road extending behind you.
• Why this works: By leaning to the right, you’re essentially shifting your perspective so that the mirror captures a wider angle of the adjacent lane. This eliminates the blind spot that would normally be present if the mirror were angled inward to show more of your own car.

4. Adjust Your Passenger-Side Mirror (Right Mirror)

• Lean to the left: Lean your head towards the driver’s side window, as far as comfortably possible. This mirrors the process used for the driver-side mirror, allowing you to set the passenger-side mirror further outward.
• Adjust the mirror: While maintaining this leaned position, adjust the passenger-side mirror until you can barely see the side of your car in the innermost edge of the mirror. Again, the focus is on maximizing visibility of the lane next to you and the road behind you, minimizing overlap with the central rear-view mirror.
• Why this works: Similar to the driver-side adjustment, leaning to the left provides a wider perspective for the passenger-side mirror, ensuring that it captures the area that would otherwise be a blind spot.

5. Verify and Fine-Tune

• Sit in your normal driving position: Return to your regular driving posture and observe the view in all three mirrors.
• Check the overlap: You should see a seamless transition between the images in your central rear-view mirror and your side mirrors. Ideally, as a car leaves your central rear-view mirror, it should immediately appear in your side mirror. There should be minimal, if any, blind spot.
• Road test: Have a friend or family member drive a car alongside you and observe how it appears in your mirrors as it moves from behind you, into the adjacent lane, and eventually past you. Pay attention to any areas where the car disappears from view.
• Fine-tune: If you notice any significant blind spots, make small adjustments to your side mirrors until you achieve optimal coverage. Remember to lean in the appropriate direction each time you make an adjustment.

Addressing Common Concerns

Many drivers are hesitant to switch to the SAE method because it feels unnatural at first. Here are some common concerns and how to address them:

• “I can’t see my own car in the mirror!”: This is intentional. The goal is to minimize the overlap with the central rear-view mirror and maximize visibility of the adjacent lanes. You don’t need to see your own car to know where it is; you already know that!
• “It feels like the cars are closer than they appear!”: This is a common misconception. Because the mirrors are angled further outward, objects may appear smaller and further away than they would in a traditional mirror setting. However, this is simply a matter of perception. With practice, you will quickly adapt to judging distances accurately using the new mirror settings.
• “I’m not used to it!”: Change takes time. Give yourself a week or two to get used to the new mirror settings. Focus on consciously checking your mirrors and observing the flow of traffic around you. You’ll soon find that the increased visibility and reduced blind spots outweigh any initial discomfort.

Benefits of Eliminating Blind Spots

Adjusting your rear-view mirrors to eliminate blind spots offers numerous benefits, including:

• Increased safety: Reduced blind spots mean fewer surprises and a lower risk of accidents when changing lanes or merging.
• Improved awareness: You’ll have a much better understanding of the traffic situation around you, allowing you to anticipate potential hazards and react accordingly.
• Reduced stress: Knowing that you have a clear view of your surroundings can significantly reduce stress and anxiety while driving.
• Greater confidence: With improved visibility, you’ll feel more confident and in control behind the wheel.

Beyond Mirror Adjustments: Other Strategies for Blind Spot Mitigation

While properly adjusted mirrors are the cornerstone of blind spot elimination, there are other strategies you can employ to further enhance your safety:

• Blind Spot Monitoring Systems (BSM): Many modern vehicles come equipped with blind spot monitoring systems that use sensors to detect vehicles in your blind spots and alert you with a visual or audible warning. While these systems are helpful, they should not be relied upon as a substitute for properly adjusted mirrors and attentive driving.
• Convex Mirrors (Spot Mirrors): Small convex mirrors can be attached to your side mirrors to provide a wider field of view. However, these mirrors can distort distances, so use them with caution and practice judging distances before relying on them.
• Over-the-Shoulder Checks: Even with properly adjusted mirrors, it’s still a good idea to perform a quick over-the-shoulder check before changing lanes, especially in heavy traffic or when conditions are uncertain. This provides a final visual confirmation that the lane is clear.
• Proper Lane Positioning: Maintain a lane position that maximizes your visibility. Avoid driving in the blind spots of other vehicles, and be aware of the blind spots of larger vehicles such as trucks and buses.
• Regular Mirror Cleaning: Keep your mirrors clean to ensure optimal visibility. Dirt, grime, and water can obstruct your view and reduce the effectiveness of your mirror adjustments.

Troubleshooting Mirror Adjustment Issues

In some cases, you might encounter challenges while adjusting your mirrors. Here’s how to troubleshoot common problems:

• Limited Mirror Adjustment Range: Some vehicles have limited mirror adjustment ranges. If you can’t achieve the desired angle, consider using aftermarket mirrors with a wider range of adjustability.
• Distorted Images: If your mirrors produce distorted images, they may be damaged or of poor quality. Replace them with high-quality mirrors that provide a clear and accurate reflection.
• Glare Issues: If you experience excessive glare, consider using anti-glare mirrors or applying an anti-glare film to your existing mirrors.

The Importance of Consistent Mirror Checks

Even with perfectly adjusted mirrors, it’s crucial to develop the habit of checking your mirrors regularly. Make it a routine to glance at your mirrors every few seconds, especially when driving in heavy traffic or changing lanes. Consistent mirror checks will help you stay aware of your surroundings and anticipate potential hazards.

Adjusting Mirrors on Motorcycles

The principles of eliminating blind spots apply to motorcycles as well. Adjust your motorcycle mirrors so that you can see the lane beside you and the road behind you, minimizing the amount of your own body that is visible in the mirrors. Due to the smaller size and shape of motorcycle mirrors, it may be necessary to use aftermarket mirrors with a wider field of view to achieve optimal coverage.

Conclusion

Eliminating blind spots is a simple yet highly effective way to improve your driving safety. By following the steps outlined in this guide and making a conscious effort to check your mirrors regularly, you can significantly reduce your risk of accidents and enjoy a more confident and stress-free driving experience. Take the time to adjust your mirrors properly, and make it a lifelong habit for safer driving.
