A. you may proceed even if it means another driver must slow down for you.
Explanation:
To "yield" means that you have to stop for a little while or slow down in order to let another vehicle move before you. Sometimes, you might see a yield sign at highway entrances or rotaries. When this happens, you must stop or slow down so you let the flow of traffic continue. However, if you have stopped at a yield sign for more than five minutes, then you may proceed, even of it means that another driver must slow down for you.
