Four people were killed and 29 others injured in a massive pileup involving over 30 vehicles, including six semitrailers, on Interstate 25 south of Pueblo, Colorado on Tuesday. Authorities say blowing dirt caused a 'brown out' with near-zero visibility on the interstate, leading to the crashes.

Why it matters

The deadly pileup highlights the dangers of sudden changes in weather conditions, especially in areas prone to high winds and dry, dusty conditions. It also raises questions about road safety protocols and emergency response plans for such extreme 'brown out' events.

The details

The crashes occurred around 10 a.m. on Tuesday when strong winds kicked up massive amounts of dirt and dust, creating near-zero visibility on I-25. In addition to the four fatalities, 29 people were transported to the hospital with injuries ranging from minor to severe. One of the vehicles involved was a pickup truck hauling a trailer with 32 goats, four of which died in the incident.
