Fire officials from both states say no engines were prevented from entering California and none of the vehicles underwent any emissions testing.

Online claims that firefighters were held up in Sacramento for emissions testing on their way to fight the blazes in Los Angeles are false, according to Oregon and California officials. The rumors have spread across social media in recent days, filling up X timelines and Facebook comment sections.

Oregon has sent hundreds of firefighters, 75 fire engines and other equipment to help battle the blazes in Southern California. But social media posts falsely claim Oregon's firefighting vehicles were "being held in Sacramento for emissions testing.

California’s firefighting agency did not reject firetrucks sent from Oregon to help with the Los Angeles fires, contrary to online posts saying the vehicles were not deployed because they didn’t meet California’s strict emissions standards.

Officials in California and the Oregon State Fire Marshal’s office have rebutted claims that a lack of "smog certification" or needing "emissions testing" kept Oregon fire trucks from aiding with the Los Angeles fire response.

The Oregon state fire marshal took to social media this week to dispel rumors circulating online about its firefighters being turned away from helping battle the wildfires in Southern California.
