Vivian, SD — March 29, 2025, An investigation underway following a bus accident that occurred at around 7:00 P.M. on I-90.
Officials are investigating after a bus accident left ten people injured on the evening of March 29th. According to official statements, a private bus was traveling on Interstate 90 near exit 201 when for unknown reasons the bus lost control and went off-road where it then rolled over on its side in a ditch.
When emergency crews arrived on the scene they found that ten people had sustained injuries seven of which were serious and three which that were minor, and they were transported to the hospital for treatment. It remains unclear at this time what caused the bus to lose control, and the identities of those involved have not been made public, however as authorities continue the investigation more details may be released in the future.
Commentary by Attorney Michael Grossman
When a bus rolls over and multiple people end up hurt, most folks assume it was just a mistake or some kind of bad luck. But in my experience, crashes like this are rarely simple. They usually involve a chain of decisions and conditions that don’t come to light unless someone takes the time to really dig.
One of the first things worth checking in any commercial vehicle crash is the data from the vehicle’s Electronic Control Module, or ECM. These devices can show how fast the vehicle was going, whether the driver braked, and what the engine was doing just before the crash. It’s not the whole story, but it’s a critical piece of the puzzle that helps show what was really happening when the vehicle left the road.
Of course, data alone doesn’t explain why the bus lost control. Was the driver distracted, tired, or going too fast for conditions? Were they trained to handle a situation like that? Did they report any mechanical issues earlier that day? These are the kinds of questions that need answers—and not all of them can be found in a police report.
Mechanical failure is another area that should be looked at closely. When brakes or steering systems stop working properly, it’s usually not just bad luck—it can point to deeper issues with how the vehicle was maintained. That means investigators need to look into the bus company’s service records, inspection history, and the decisions made leading up to the trip.
What concerns me most is that many investigations stop at the crash scene. Authorities usually do their best, but they often don’t have the resources or time to look beyond the obvious. Without a deeper investigation—one that includes company practices, driver history, and maintenance decisions—it’s easy for the real cause of a crash to go unnoticed.
That’s why it’s so important to ask hard questions and follow the evidence wherever it leads. The people who were hurt deserve answers based on a full investigation, not just what could be seen at the side of the road.
