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.

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.

Fire trucks traveling from Oregon and other states to help fight the California wildfires were stopped for routine 15-minute safety checks, not emissions testing.

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.

Crews from neighboring states are helping California fight the Los Angeles area fires, and officials say regulations are not holding them up.
