Rio,

I have been in the insurance industry for many of years. What you did is very typical and you are allowed to proceed thru an intersection on a yellow as long as your rear wheels are in the start of the intersection before it turns red meaning --- the line where the curb is at on both sides of the street ( this is the intersection ) And yes you are correct saying that red light runners kill but on the same note you didn't run a red light you entered on a yellow that turned red ....

Take it easy on yourself you are young and us older drivers do the samething tooo in your case

Take Care

Tymber

Peace OUT
