The crash occurred Saturday near the town of Vyborg when a Volkswagen van drove into the oncoming lane and collided with the logging truck, RIA Novosti reported.
Ten people died at the scene, and two van passengers and the driver of the truck were in intensive care.
Local officials said there was black ice on the road that caused the van to skid into oncoming traffic during a turn.
A criminal probe was under way, and prosecutors said they were investigating whether the road's maintenance may have led to the tragedy.
The section of the road where the crash occurred is rented by Finland, which is responsible for its maintenance, prosecutors said.
