I was actually RIGHT NEXT TO THE RV when this happened and only myself and one other vehicle made it past the RV when this happened. The RV blew a front tire which caused the accident. I heard the "POW!", looked to my right and saw the front end drop down. Luckily it was the passenger side b/c had it been the driver side, it may have pulled right into us! I looked in my rearview to see if they were able to pull off the road when all of a sudden the RV turned sideways (taking up multiple lanes on the freeway) and rolled over on it's side. Thank goodness there were no injuries!
