Firefighters halted the spread of a brush fire in Chino Hills, California, that was sparked by a single-vehicle rollover crash, fire officials said. The blaze, named the Grand Fire, burned about 30 acres.
The fire briefly threatened hundreds of homes as it moved through dry vegetation near a residential area before crews brought it under control.
More than 200 firefighters responded, mounting an aggressive ground and air attack that stopped forward progress before the flames reached structures.
Vehicle crashes are a recurring ignition source for wildfires in Southern California, where roadside brush can dry out quickly and catch from hot debris or sparks.
The incident underscored the elevated fire risk in the region’s wildland-urban interface, where neighbourhoods abut open hillsides, even early in the season before peak summer heat.
