After arriving to the scene, rescuers made it into the bus through the main windshield and the hatch, rescuing the five people who were injured. The rest made it out safely on their own.
None of the passengers were seriously injured.
The police think the bus crashed due to a slippery road or inappropriately high speed. Latvia's State Police ask drivers to be extra careful during the current snowstorm and opt for a safe driving speed.
