I was driving down highway 60 when my van backfired. I thought it was a blown tire & started pulling off the highway. When pulling off the highway I noticed the orange glare off the side rails on the highway. That's when I realized that the van had caught on fire under the hood. Once I pulled over I had a friend call 911 to report my van on fire while I tried to open the hood & put the fire out. The hood was to hot to open so I grabbed everything I could from my van & stayed clear of it until the Arizona fire dept & Arizona highway patrol came. All my information was taken by the Arizona highway patrol. I was told that my van will be at J&S Towing & that my friends & i can leave the scene.
