Woods Cross, UT (July 7, 2026) – Two people were taken to a hospital in critical condition on Saturday night after a three-vehicle crash near the I-15 on-ramp at approximately 2600 South in Woods Cross. The collision occurred just before 9:15 p.m. on July 4.
Traffic had slowed in the area due to a separate rollover crash roughly two miles north in Bountiful. A driver failed to reduce speed and struck a Subaru at high speed. The force of that impact pushed the Subaru into a third vehicle.
Both occupants of the Subaru were transported to a nearby hospital in critical condition. The on-ramp and lanes three and four were closed until approximately 10:15 p.m. No identities were released following the wreck. The cause of the accident is still under investigation.
We are keeping both people in our thoughts and hope for their full recoveries.
How Do Secondary Crashes Form When Traffic Slows for an Upstream Collision?
When a crash occurs on a highway and traffic backs up behind it, the tail end of that backup becomes a hazard of its own. Drivers approaching the slowdown from behind may not see the stopped or slowing vehicles in time to brake safely, particularly at highway speeds where stopping distances are long. A single driver who fails to react quickly enough can trigger a second crash that is entirely separate from the original one but directly caused by it.
This pattern, sometimes called a secondary crash, is one of the more common and preventable types of highway collisions. The risk is highest in the first few minutes after the initial crash, before warning signs, traffic control, or emergency vehicles have been positioned to alert approaching drivers. Dashcam footage and dispatch records show that secondary crashes happen within a short window of the first collision, before the scene has been fully secured.
High-speed rear-end crashes that push one vehicle into another can result in a chain of force that each successive vehicle has no way to absorb. The occupants of the middle vehicle, in this case the Subaru, experience the combined energy of the striking vehicle from behind while simultaneously being driven into the car ahead. This double-impact dynamic is one reason why chain-reaction crashes on highways so frequently result in serious or critical injuries to those caught between vehicles.
