St. Louis, MO (March 4, 2026) – Three people were injured in a multi-vehicle crash on Wednesday, March 4, on southbound I-270 just south of I-44 in St. Louis County. The collision occurred at approximately 1:20 p.m.
According to the crash report, a 2023 Mitsubishi Outlander began to hydroplane due to the wet roadway. The right side of the SUV struck the front of a 2014 motor home before hitting the front of a 2018 Hyundai Sonata.
The 40-year-old driver of the Mitsubishi, along with the 35-year-old driver of the Hyundai and a 34-year-old passenger in the Hyundai, were all reported to have minor injuries. They were taken to Mercy Hospital South for treatment.
All three vehicles sustained heavy damage and were towed from the scene. The incident remains under review by authorities.
We are thinking of those injured as they recover.
Why Hydroplaning Can Lead to Highway Collisions
Hydroplaning happens when a layer of water builds up between a vehicle’s tires and the road surface. When this occurs, drivers can lose traction and steering control.
Wet highways increase the risk, especially at higher speeds. Even small amounts of standing water can cause a vehicle to slide unexpectedly.
When a vehicle hydroplanes in traffic, it may drift into adjacent lanes or strike nearby vehicles. Multi-vehicle crashes can happen quickly if drivers do not have enough time or distance to react. Proper tire maintenance and reduced speeds during rain can help lower the risk of this type of accident.
