A man and a woman in their twenties were riding the motorcycle at the time, following a long-haul truck.
Suddenly an elk rushed out into the road and the truck driver slammed on the brakes.
The driver of the motorcycle swerved to avoid hitting the truck, only to then collide with the elk which came flying through the air after having been hit by the truck.
Both the man and the woman were taken to hospital with serious internal injuries and fractures.
There was no report on the condition of the elk.
