Follow the four rs (read, right, reduce, and ride) when ________.

Answer 1

Follow the four rs (read, right, reduce, and ride) when avoiding head on collision

here are the four r's : 
read the road ahead, so you have enough time to response

drive to the right, because it is most likely to be empty

reduce your speed, so the impact will be minimized

ride off the road, so you wouldn't be a hindrance for the traffic
