Side mirrors in your car and motorcycle are meant to stay firm and sturdy with optimum visibility. So, when it starts vibrating, there’s every reason to get worried since it will reduce visibility. Also, a vibrating side mirror can cause accidents without the driver’s fault.

Hence, you must know how to fix side mirror vibration for safe driving to ensure better road visibility. For this, you must understand the reasons for vibrating side-view mirrors so that you can observe and identify the reasons for fixing them.

The side view mirror often vibrates due to excess wind speed, loose nuts, an inaccurate suspension system, and loose mirror housing. Thus, you can stop the side mirror vibration by properly tightening the screw, mirror housing, and suspension system. Also, you may upgrade to a sturdier aftermarket side view mirror for better results.

Is a Vibrating Side Mirror Dangerous?

When the side view mirror vibrates, you may not pay attention to it. However, a vibrating side-view mirror is one of the major reasons for accidents on the road. It reduces visibility, distracts the driver’s attention, and might cause mechanical issues for the mirroring system.

Reduced Visibility

A vibrating side mirror drops your visibility more significantly than you can imagine. Also, a side mirror popped out would drop a driver’s ability to see behind and beside their vehicle. So, drivers get blinded by their surroundings and don’t know what’s coming beside them.

The vibration on the mirror causes distortion. So, it becomes difficult to gauge the distance and speed of approaching vehicles accurately. As a result, drivers may need to be more accurate with the safe gaps between the vehicles. It happens during:

  • Merging
  • Changing lanes
  • Making turns

All these will increase the likelihood of collisions. The problems become acute in adverse weather conditions or at night.

The vibration on the side mirror will amplify the glare from headlights and precipitation. So, it gets even harder for the driver to discern the traffic around them.

Distracted Driving

A vibrating side mirror will constantly move. So, it can be highly distracting for drivers. Also, the vibrating mirror will attract their attention. It takes their focus away from monitoring the road and other vehicles.

And as you know, distracted driving is one of the leading causes of accidents. It reduces the driver’s reaction times, anticipation, and response-ability to potential hazards. Also, the constant sound of a vibrating mirror is distracting for drivers.

Potential Mechanical Issues

A vibrating side mirror might indicate underlying mechanical issues in the vehicle, too. It can be a symptom of:

  • Problems with the mirror’s mounting
  • Mirror adjustment mechanism
  • The inaccurate and damaged suspension system
  • The overall stability of the vehicle.

Thus, you can’t ignore these vibrations caused by the vehicle. Or else it can lead to more severe issues that might result in expensive repairs.

Reasons for a Vibrating Side Mirror:

Why does the side mirror vibrate in the car? Is it natural or due to any reasons? These questions may have hit your head hard. So, here’s the short answer:

A side view mirror in a car or motorcycle may vibrate due to excessive wind speed, loose mounting of the mirror housing, loose nuts, and too much vibration in the road. Also, a motorcycle side view mirror can vibrate due to a loose handlebar, putting too much pressure on the handlebar, and an inaccurate and damaged suspension system.

Before you get into how to fix a vibrating side mirror, let’s understand the reasons more.

Wind Turbulence:

Wind turbulence is a common reason for side mirror vibration. It happens particularly at higher speeds and where the wind speed is too high.

You will notice the phenomenon more in vehicles with larger and more aerodynamically exposed side mirrors. As the wind hits the side mirror at higher speeds, the mirror will jerk and vibrate. Plus, the shape and positioning of the side mirror may be responsible for unwanted vibration.

It can influence the wind turbulence your vehicle experiences. Thankfully, mirrors with streamlined designs and closer to the vehicle’s body are less susceptible to vibrations due to wind turbulence. You may install newer and sturdier mirrors to fix the problem.

Loose Mounting:

The mounting of side mirrors involves several screws and bolts. These nuts and screws secure the mirror housing to the vehicle’s door or frame. Over time, the screws become loose due to regular wear and tear.

As the mounting hardware gets loose, the side mirror will move slightly. It will lead to vibrations during driving.

Vibrations from the Road:

Uneven road surfaces, potholes, and rough terrains can generate vibrations when you travel through these roads. As your vehicle vibrates, it can transmit to different components of your vehicle. It includes:

  • The side mirrors
  • The windshield of your car
  • Interior seats and moveable items

Therefore, the mirror housing might shake, resulting in blurred or distorted reflections. Since it depends on road conditions, you can only do a little about this side view mirror vibration reasons.

Mirror Damage:

Impacts or collisions can damage the side mirrors. Even if the collision is seemingly insignificant, it can crack mirror glass or misalign the mirror housing. Since it will disrupt the smooth movement of the mirror, the mirror will start vibrating. 

Also, side view mirror housing may get cracked over time for unknown reasons. It will cause the mirror to vibrate, too. It may even stop the mirror movement, and you will find the side mirror won’t go up and down.

Mirror Motor Malfunction:

Many automobiles these days have electrically adjustable side mirrors. These mirrors depend on small electric motors to move and adjust the mirror position.

At times, these motors malfunction or become faulty. So, they fail to maintain the mirror in the correct position, leading to vibrations. A few causes of motor malfunctions include:

  • Electrical issues
  • Wear and tear
  • Water damage

The loose handlebar of motorcycles:

Side-view mirrors on motorcycles sit on the edge of the handlebar. So, when the handlebar becomes loose, it can also affect the side view mirrors. Also, holding the handlebar with too much pressure or putting something on it may become shaky.

All this extra weight, pressure, and loose handlebar might lead to a vibrating side-view mirror. So, you must be careful about the handlebar condition in your motorcycle to avoid vibrations.
