According to an article in Sport.cz, as translated by several media outlets, Voracek was speeding down a small road when a truck coming from the opposite direction slowed down to make a left hand turn.
In an attempt to avoid the truck, Voracek bumped into another car, a Mercedes, hit the truck, bounced into a tree and collided with a telephone pole. Alcohol was not a factor.
"(Voracek) failed to comply with safe distance from the vehicle ahead," Kladno police spokeswoman Michaela Novakova told Sport.cz.
In a statement released by the Flyers, Philadelphia GM Paul Holmgren confirmed Voracek was not hurt in the crash.
"I spoke with Jake this morning," he said. "He was involved in a car accident in the Czech Republic. Although his car did suffer damage, there were no injuries. Jake is fine."
