One thing I noticed today...golf carts need to get merged into traffic. I had one wait till the last second and I didn't see the merge sign so he was kinda stuck. There had been no one in front of me at that time so he should have merged out earlier. Take the right of way guys...merge...merge..don't wait till the cars are on top of you and you don't know what to do! Waiting gets you hung up or causes a problem.
To answer the question of the OP I believe whoever gets there first...however there are posted signs stating cars are suppose to yield to bike/carts in that golf cart lanes. NOt posted everywhere but have seen them on occasion north of 466. Just think of it as you wouldn't turn right directly in front of a golf cart...they're suppose to go and then you cross that lane. I normally hang back and let golf carts go ahead if they're running in front of me or if there is space I get out ahead of them not to impede.
Of course I'm still fuming over the moron bicyclist this afternoon whom I nearly ran square into because of his actions. :
:..on that note...just watch it...idiots abound.
