A collision between an SUV and a semi-truck on the Yellowhead Highway west of Lloydminster in Alberta has resulted in the deaths of one woman and two children, with a fourth child in critical condition. Emergency services responded to the crash shortly after midnight.

The incident occurred on a stretch of the highway known for heavy traffic. Witnesses reported that the SUV veered off the road before colliding with the semi-truck. Local authorities confirmed that the driver of the SUV was not immediately located.

This is the second major road accident in the region this month. A similar crash on the same highway earlier this month left three people injured. Officials have called for increased safety measures on the route, citing frequent accidents and poor visibility.

The Yellowhead Highway connects Alberta to British Columbia and is a key route for commercial transport. The recent incidents have raised concerns among local residents and transport officials. Investigations into the cause of the crash are ongoing.
