It's what you might call a rookie error.
First year Supercars drivers Richie Stanaway, Todd Hazelwood and James Golding all learnt a hard lesson about life in Australia's premier motorsport category on Saturday.
Among five drivers making their Supercars debut as fulltime racers in the 250km race at Adelaide's street circuit, the trio were all involved in a crash 56 laps into the 78-lap event.
While Ford driver Hazelwood managed to limp his damaged Falcon back to pit lane for repairs, Golding and Stanaway joined Tim Blanchard as the only drivers who failed to finish the race.
