Des Moines, IA – Iowa drivers are being urged to slow down this week after new data from the Iowa State Patrol shows that most winter crashes occur when snowfall totals are small—not during major storms. The department shared a safety infographic reminding motorists that “less snow doesn’t always mean you’re good to go.”
According to the Iowa State Patrol, nearly 75% of weather-related crashes in Iowa from 2018 to 2020 happened with less than 2 inches of snow. The agency says the misconception that roads are safer during lighter snowfall continues to contribute to preventable collisions each winter.
Crash data shows that trace to 1-inch snow events accounted for more than half of all weather-related crashes, while heavier snowfall totals of 4 inches or more made up a much smaller portion. Troopers note that lighter snow often creates a thin, hard-to-see layer of slick pavement—especially during morning and evening commutes.
Officials are reminding drivers to slow down, increase following distance, and stay updated on road conditions through 511ia.org. Even minor accumulation, they said, can reduce tire traction and extend stopping distances, particularly on bridges, overpasses, and rural highways across Polk County, Warren County, Dallas County, and the greater Des Moines metro.
Troopers also emphasized putting phones away and remaining alert as winter weather patterns shift across Iowa in the days ahead.
“The majority of crashes can happen in 2 inches or less,” the agency said in its advisory. “Buckle up, put the phone down, and slow down.”
