[Back in Black]

Great advice about the fire extenguishers. I had a gasoline fire as a young man in my dad's ford truck, and the fire dept put it out . Still toasted the wiring in the motor compartment, although the motor was OK.
Carry a razor sharp pocket knife, clipped where you can draw and use it, and CUT THRU THOSE SEAT BELTS if you must. Do NOT hesitate...he who hesitates is a weenie roast!
One try at the seat belt and then my knife would come out. You might also be able to save a friend at a race or on the street with such a knife. Most who will not use it as a weapon ( and all racers, etc...) should get a safety tip type like the Spyderco Rescue or Rescue Jr. OR the (more bulky, but has a glass breaker) Smith and Wesson 1st response knife.
Can you imagine watching your friend, wife or anyone else burn alive in a seat belt while you watch, because you had no knife? Carry one, the best one you legally can.
