Berlin - Former top cyclist Jan Ullrich will appear before a Swiss judge on charges of drink driving dating from May 2014 when he caused an accident in which two people were injured.
"It's inexcusable to have driven in the state I was in. It was a terrible mistake, and I deeply regret it," said Germany's Ullrich, the 1997 Tour de France winner.
Ullrich risks a fine and jail sentence of up to three years if found guilty.
His car raced through an intersection and hit a parked car before skidding and hitting another car head on in the region of Thurgovie.
