One person is dead after a vehicle collided with a power pole near Sylvan Lake early Saturday morning.

The vehicle failed to stop and a short time later the vehicle leapt off the road and crashed into a power pole.

Mounties said the driver was ejected from the vehicle and was killed. The passenger suffered serious injuries and was transported by EMS to the Red Deer Regional Hospital
