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.

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

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.

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

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.
