California Driving: How to set your car's mirrors to really see your blind spots

Do you turn you head to check your blind spot before making a lane change? Here in congested San Francisco, turning your head even briefly away can increase your risk of being in a car accident. There's a way to reset your mirrors that makes head turning unnecessary. It's the Blindspot and Glare Elimination (BGE) mirror setting. The BGE was developed in 1996 by a member of the Society of Automotive Engineers (SAE) named George Platzer. The BGE setting changes the view of your side mirrors to show your blind spots, rather than the view behind, which is already covered by your rear view mirror. An added benefit of the BGE setting is the elimination of glare from passing cars.

For drivers who are accustomed to the typical side mirror settings, switching to the BGE setting is a bit difficult initially, due to disorientation when looking at the side view mirror when the side of their vehicle is no longer visible, but after switching, most acclimate to the new settings and find it a better way to drive.

There are several advantages to the BGE setting:

  • You no longer have to turn your head to look into the blind zones.

  • Only a brief glance at the mirrors is needed to change lanes.

  • By glancing at the mirror, you keep the road ahead in your peripheral vision. Turning your head completely eliminates the road ahead from your field of vision.

  • Glare from the side mirrors is almost entirely eliminated. You should no longer have a trailing car's headlights shine directly into your eyes.
  • The BGE setting involves tipping your mirrors out about 15 degrees farther than the typical setting. Here's how to do it:

    Place your head against the driver's side window and adjust the driver's side mirror so you can barely see the driver's side of your car. (This is the view you would have on typical settings without moving your head.)

    Move your head as close to the center of the car as possible and adjust the passenger's side mirror so you can barely see the passenger's side of your car.

    To check your BGE setting, watch as a car passes you in an adjacent lane. It should enter your outside mirror before it leaves the rearview (inside) mirror. Also, the car should appear in your peripheral vision before it leaves the outside mirror.

    To use the mirrors with the BGE settings, check your rearview first to see if anyone is coming up from behind, then just glance in the sideview mirror.

    I switched to the BGE setting, and have found myself wishing I had been using BGE all along.
