Ok folks enlighten me. I've lived in Oklahoma for 3 years now, but there's one thing I can't get used to, yield signs on the highway merge lanes. As I'm getting ready to merge on the highway...I'm looking over my left shoulder to make sure I'm clear. Next thing I know someone in front of me puts on their brakes and come to a complete stop. Everywhere I have been has merge signs in the merge lanes not yield signs. This seems like a HUGE safety issue to me.
