NASCAR has made a significant change in the inspection process for 2017.
In years past, if a car failed one the inspection stations, the team would pull it out of line, make repairs and send it back on through.
This year, though, if a car flunks any part of inspection, it has to go through the entire process again.
"That was a reaction to several different things with several different people's input," said [NASCAR Senior Vice President of Competition Scott] Miller. "The teams were struggling with some of what was going on. NASCAR was struggling with some of what was going on in the old process, as well as the O.E.M.s (automakers)."
"We as a sanctioning body have more of a way to kind of maintain custody of those cars as they go through inspection and make sure that the teams aren't passing one station and then working on the car to circumvent that station as they pass through the rest," said Miller.
