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.

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.

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.

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