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.

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.
