Selecting the right pry bar can take some thought. You want one that is long enough to have good leverage, but one small enough that it can fit easily on to the tow truck. Not long ago, the tow truck was also to keep tools on board to help with extrications at accident scenes. It was and still could be one of the most critical tools to have on board if needed to pry a jammed door open to help a motorist retreat from a damaged vehicle. These days, Firefighters are equipped and trained with the most stat of the art tools to ease the process of extracting persons from vehicles. Even still, the tow truck should always have a strong pry bar on board.
