According to Oregon and California’s fire departments, trucks were stopped in Davis, California, just outside Sacramento, for maintenance and safety checks, and those trucks continued onward. Photos and news coverage confirm that trucks from other states were assisting firefighters in Los Angeles.

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.

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 and Oregon officials denied that fire trucks from Oregon were substantially delayed by California safety checks while rushing to fight the fires.

After Oregon sent 300 firefighters and 75 engines to help fight the LA fires this week, rumors began circulating that equipment and crews had been stopped for 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.

California’s call for help meant a quick mobilization for the Oregon Department of Forestry’s strike teams. Within 24 hours, six teams were en route to help tackle the blazes, and they’re making an impact according to an ODF representative on the ground in LA County.

Forecasters said winds were expected to return Monday as crews work to control the fires. Red flag warnings were issued by the National Weather Service for Santa Barbara, Ventura and Los Angeles counties.
