The winter months can lead to treacherous roadways. It is important for drivers to be vigilant of the possible changing conditions on the roads and adjust their driving accordingly. Auto accidents can lead to serious injuries with lengthy recoveries and in some tragic instances, can lead to death.

Sadly, two sisters died earlier this month, near Alamosa, Colorado, when their vehicle collided with a semitrailer. A Colorado State Patrol spokesperson says the car accident happened on Colorado Highway 160, roughly three miles west of Alamosa, shortly before 4:45 p.m.

According to police reports, a 44-year-old Center, Colorado woman was driving west on Highway 160 in a 2006 Saturn sedan. The woman apparently lost control of the vehicle on icy roads and spun into the path a semi traveling east.

A 45-year-old man from Fayetteville, Arkansas was driving the semi at the time of the accident. After the car crash, the semi rolled onto its right side, according to police reports. The semi was carrying a load of potatoes.

A staff member from the Alamosa County Coroner's Office pronounced the 44-year-old driver of the Saturn sedan dead at the scene of the accident. Her 50-year-old sister, a resident of Ranchos De Taos, New Mexico, also died in the wreck. Both sisters were wearing their seatbelts at the time of the collision.

The 45-year-old semi driver was not injured in the accident. He was also wearing his seatbelt when the collision occurred, according to the police report.

Neither driver is suspected of using alcohol or drugs prior to the wreck, according to the Colorado State Patrol.

The Colorado State Patrol spokesperson urged drivers to be prepared for quickly changing road conditions during winter weather. Highway 160 was relatively clear to the east and to the west of the accident site. However, the section of road where the accident happened was icy and covered with snow.
