Discription of Events: Car was tailgating and honking when I yielded to an ambulance, cut me off and tried forcing me off the road while yelling and throwing hand gestures. Cut off the ambulance then slowed down (slowing down an ambulance with lights on) then got back by me trying to force me off the road again finally tricked them into taking an exit then backed out at last minute and got back on interstate and she yelled and shook hands out of the window while almost rolling the car
