Always Check your blind spot when merging!

Checking Your Blind Spots

A “blind spot” is defined by the area where your rear view mirror view ends, before your side view mirror view begins and your peripheral vision does not see. It is generally right beside you over your left or right shoulder. A vehicle can be in this spot and be completely hidden from your view. To avoid crashes always check your blind spot before changing directions. When checking your blind spot, you should quickly glance, returning your eyes immediately to your forward path of travel. Your left blind spot is checked by quickly glancing over your left shoulder. Your right blind spot requires a quick glance through the rear passenger window. Your shoulders should remain square in your seat. Resist the temptation to lift yourself from your seat and scan the entire lane beside you. If your side view mirrors are adjusted properly then your blind spot will only be essentially Be just beyond your peripheral vision.

Do not take your focus off the road in front of you! In order to check your blind spot, mirrors, side of the road and speedometer practice quick glances, returning your focal point to your forward line of sight. Your eyes should never leave the road for more than one second. Your L.O.S. =P.O.T.

BGE : Blind Glare Elimination

By setting your mirrors in the BGE (blind, glare elimination) settings, with side view mirrors 7 degrees out, you can greatly reduce your blind spots. Even eliminate them completely when set properly, but it is virtually impossible to totally eliminate the blind spot for very small vehicles, motorcycles or pedestrians, so it is important to take the over the shoulder glance. You can apply a convex mirror to your rear view mirror, but these will distort the image and require some getting used to. It is still a good idea to develop the habit of glancing over your shoulder to check for your blind spots for a motorcycle, bicycle or small vehicle.

The following lists the situations in which you should always check your blind spot before performing.

Five times to glance over the shoulder to check blind spots

When swerving around an object

Be sure to signal. Glance in your rear view mirror; check your side view mirrors and blind spot before swerving to miss an object in the road. Be sure to glance in the rear view mirror for potential rear end collision and tap the brake before stopping suddenly to avoid hitting an object in front of you. For example, if a small animal runs out on the road and you must swerve, be sure and check your blind spot. In this case you must determine the best maneuver to avoid hitting an animal. Scanning the areas around your vehicle on a continual basis in order to be aware of the traffic situation can aid you in your decisions. Knowing if there is a car right beside you or close behind you can help you to determine the safest maneuver in these conflict situations.


When turning right at a green light, on the opposing curb, pedestrians may step out to cross with the red light. Check your blind spot to the right for pedestrians or bicyclists that you may have missed. Of course this is especially true in busy pedestrian areas! When making a left turns, quickly check your blind spot before entering a left turning lane, even at the beginning of a changing lane, cars may misinterpret your intention to enter the lane and try to accelerate past you. Check before entering.

Changing Lanes

When changing lanes always signal, check your rear view mirror, your side view mirror, glance over your shoulder at you blind spot and go (S.M.O.G.). Unless traffic in the lane is slowed, maintain your speed or speed up during lane changes.

This is an occasion when you need to check your blind spot more than once. Begin glancing over your shoulder for the place where you want to enter the road way while in the accelerations lane as soon as traffic on the main road enters your line of sight (LOS) and then ALWAYS check your blind spot just prior to merging.

Entering traffic from a parking space

This is another occasion when you should check your blind spot twice. Signal your intention to pull out from your parallel parking spot, check your blind spot and prepare to pull out of your place. Check your blindspot again right before merging into the traffic. Always be sure to signal before pulling out from a parallel parking spot, this oversight potentially carries a three point violation ticket and is dangerous to you.

Which of the vehicles are traveling in someone else blind spot?

Always avoid traveling in someone else’s blind spot if possible. When checking your blind spot on multilane roads, be sure to check across all lanes before changing lanes, making sure no other vehicle is planning to change lanes at the same time you are. If you are in a situation where you cannot avoid driving in another vehicles blind spot, especially large vehicles, watch the front tires of the truck next to you and have a plan, or open spot, to escape to. Large trucks have large blind spots, particularly on the right side. Try to avoid traveling in these areas.
