Have you ever started to make a lane change and narrowly avoided a collision with another vehicle, because you were unaware they were beside you. You checked your side mirrors and rearview mirror and thought it was clear to proceed to a new lane; however, you forgot to check your "Blind Spot." A blind spot is an area around your vehicle, which is not visible while at the controls of your vehicle, under existing circumstances. Unfortunately, according to Standard Traffic Ordinance 46, you would have been at fault if a collision happened.
Standard Traffic Ordinance 46 (A) on Driving on Roadways Laned for Traffic states, “Whenever any roadway has been divided into two or more clearly marked lanes for traffic, the following rules in addition to all others consistent herewith shall apply. A vehicle shall be driven as nearly as practicable entirely within a single lane and shall not be moved from such lane until the driver has first ascertained that such movement can be made with safety.”
There is a simple solution to solve the "Blind Spot" issue, so you can make a safe lane change or turn. Remember to turn your head to check over and behind your shoulder in the direction of your intended movement, in addition to checking your rearview and sideview mirrors. When we all do this, we avoid collisions and make the roadways safer.
