Emery County, UT — May 21, 2025, a motorcyclist was killed in a tanker truck accident at approximately 12:30 p.m. along U.S. Highway 6.

According to authorities, a 57-year-old man from the Netherlands was traveling on a westbound motorcycle on U.S. 6 in the vicinity several miles west of Woodside when the accident took place.

The road in that area apparently had a steep incline; due to that fact, a tanker truck had activated its hazard lights as it had speed had decreased. Officials indicate that, for as yet unknown reasons, a collision took place between the front-end of the motorcycle and the rear-end of the tanker.

The motorcyclist reportedly suffered fatal injuries as a result of the wreck. Additional details pertaining to this incident—including the identity of the victim—are not available at this point in time. The investigation is currently ongoing.

Commentary by Attorney Michael Grossman

When people read that a motorcyclist rear-ended a slow-moving tanker truck, many assume it's an open-and-shut case. But as someone who’s handled a fair number of commercial vehicle cases, I can say that crashes like this often raise more questions than they answer—especially when someone loses their life and the public narrative leans too heavily on assumptions.

Here’s what we know: a tanker truck was moving slowly uphill on a steep grade and had its hazard lights on. A motorcyclist came up behind and, for reasons not yet explained, collided with the rear of the tanker. That’s not much to go on, and several critical unknowns are still in play.

What Doesn’t Add Up

Let’s start with what we don’t know. Was the truck moving or nearly stopped? Were the hazard lights actually functioning at the time, or was that simply the driver’s claim after the fact? Was the motorcycle rider given enough time and space to react?

I’ve seen cases where commercial trucks traveled below highway speed on inclines without proper warning markings, faulty lighting, or even improperly secured loads that limited rear visibility. Just because a truck is legally allowed to be on the road doesn’t mean it’s doing everything it should to prevent rear-end collisions.

On the flip side, if the motorcycle was speeding, distracted, or riding too close, that could shift the narrative significantly. But as of now, there’s no information on the rider’s behavior, which makes it impossible to draw firm conclusions.

Evidence That Could Clarify Responsibility

Getting to the truth will depend on evidence—evidence that likely isn’t visible from a quick glance at the scene:

• Dash camera footage or rear-facing cameras on the truck could confirm whether the hazard lights were on and visible.
• The ECM data could tell us how fast the truck was going and whether it slowed suddenly or gradually.
• Skid marks or lack thereof could indicate whether the motorcyclist tried to brake or never saw the truck in time.
• Lighting inspections on the tanker truck might reveal if a faulty taillight made the truck nearly invisible in daytime shadow or glare.

It’s also worth considering whether the truck was carrying hazardous materials, which sometimes trigger stricter visibility or lighting requirements.

Accountability Is a Two-Way Street

In my experience, rear-end collisions involving commercial vehicles often get written off as driver error on the part of the trailing motorist. But that conclusion skips past deeper questions about visibility, equipment condition, and how clearly a truck signaled its presence and intent. I once litigated a case where a rear-end crash was initially blamed on the driver behind—until we proved the trailer's brake lights weren’t functioning at the time of the wreck.

That’s why an independent investigation is essential. Not just to hold someone accountable, but to make sure it’s the right someone—based on facts, not assumptions.

Key Takeaways

• The cause of the crash remains unknown, and it’s too early to determine fault.
• Evidence like camera footage, ECM data, and lighting inspections will be crucial to understanding what really happened.
• The visibility and conduct of the tanker truck must be scrutinized as much as the motorcyclist’s.
• Rear-end crashes involving commercial trucks are rarely as simple as they first appear.
• Only a full investigation can determine whether this crash was preventable and who, if anyone, failed to do their part.
