SALAGNON, ISÈRE, FRANCE — A serious multi-vehicle collision on the RD 522 in Salagnon prompted a major emergency response Thursday evening, September 10, 2026, leaving several people injured and temporarily closing the road.

The crash happened shortly after 6 p.m. on Route du Bugey, where three cars and a utility vehicle were involved in a collision.

Emergency crews, including firefighters, the SMUR medical team from Bourgoin-Jallieu and an air medical team, were dispatched to the scene.

What Happened on the RD 522?

The collision occurred shortly after 6 p.m. along the RD 522 in Salagnon.

The vehicles involved included three passenger cars and a utility vehicle. Initial reports indicated that six people were involved and that several had sustained injuries.

A later update provided more detail, stating that four of the six people involved were injured, including a 21-year-old man whose condition was considered particularly serious.

21-Year-Old Man Airlifted to Lyon

One of the most seriously injured people was a 21-year-old man who was classified as being in absolute emergency.

He was transported by medical helicopter to the Édouard-Herriot Hospital in Lyon, where he was taken to the emergency trauma department for treatment.

The condition of the other injured people was not fully detailed in the available reports.

Major Emergency Response

The seriousness of the crash prompted a substantial emergency response.

Several teams of firefighters attended the scene alongside the SMUR medical team from Bourgoin-Jallieu and a helicopter medical team.

Medical crews assessed those involved while firefighters worked to secure the crash scene and assist with the emergency operation.

The presence of multiple injured people required coordinated medical and rescue efforts.

RD 522 Closed After Collision

The crash also disrupted traffic through Salagnon.

Gendarmes closed the RD 522 to allow emergency services to work safely at the scene. A local diversion was established while the road remained unavailable to normal traffic.

Drivers travelling through the area were therefore advised to use the designated diversion and allow additional time for their journeys.

Circumstances Under Investigation

The exact circumstances surrounding the collision were still being examined.

A later report indicated that a slowdown caused by a harvester leaving the RD 522 to enter a smaller road may have played a role, with one driver apparently failing to anticipate the traffic conditions. However, that remains part of the reported early account of how the collision occurred and should not be treated as a definitive finding.

Authorities will determine the precise sequence of events as the investigation continues.

Community Awaiting Further Information

The crash has drawn attention in Salagnon because of the number of people involved and the severity of some of the injuries.

At the time of reporting, no fatality had been reported in connection with the collision.

The priority for emergency crews remained treating the injured, securing the roadway and allowing investigators to establish what happened.
