It recorded at least 26,000 fake tickets over a five-year period, involving hundreds of officers.
The figures skewed racial profiling data to appear like more white people were being stopped.
One trooper singlehandedly logged 1,350 fake tickets between 2014 and 2017, the audit, released late last month, revealed.
As a result, police skewed racial profiling records, making it appear that more white people had been stopped than was the reality, it said.
It was unclear if the fake tickets were deliberately falsified or were the result of human error, it said.
