Injury-troubled Reus, 25, is accused of driving without a license at least six times between September 2011 and March this year.
“He'll therefore be paying a total fine of €540,000 over 90 days”, head Dortmund prosecutor Henner Kruse told Bild, adding that he based the fine on Reus' monthly income of €180,000.
It's another black day in a miserable year for the winger, who missed out on the World Cup in Brazil and many club games due to successive injuries.
According to the newspaper, Reus never passed his driving test.
“Unfortunately I then decided to take this path. I can't even justify it to myself any longer”, he said. “I was much too naive”.
Police discovered that Reus was driving without a licence when they pulled his sports car over for a routine stop in March.
But Bild reported that he had also been caught out by speed cameras several times in recent years.
“I've learned my lesson. I'll never do anything like this again”, Reus said, adding that he would sign up for driving lessons and take the test.
