It was a deadly weekend on Montana’s highways.
Investigators think speed, drugs and alcohol all played a part in a double fatal crash near Plains.
A driver slammed into a rock wall on State Highway 28 in the early hours of Saturday morning after failing to negotiate a turn.
A passenger was ejected from the car in the crash. The driver and that passenger were killed, and have not been publicly identified.
The Highway Patrol is still investigating a deadly motorcycle crash on the Eastside Highway near Stevensville.
Investigators think speed and alcohol may have contributed to that crash as well, which happened Saturday evening, when the rider went off the road on a curve.
The 55-year-old was killed after he hit a fence post. No one else was injured in the crash.
And a man died in a separate motorcycle crash at the Montana-Idaho state line just northwest of Troy.
The Highway Patrol says the motorcyclist laid his bike down in the early hours of Sunday morning on U-S Highway 2 after going around a corner.
Investigators aren’t sure what caused the crash, but don’t believe alcohol or drugs were involved. No one else was onboard the motorcycle when it crashed.
