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

California’s firefighting agency did not reject firetrucks sent from Oregon to help with the Los Angeles fires, contrary to online posts saying the vehicles were not deployed because they didn’t meet California’s strict emissions standards.

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.

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.

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.
