Thick Fog Causes 59-Vehicle Pile-Up on California Highway
A very thick fog made it hard to see on a highway in California.
This caused a big crash with 59 cars involved.
Ten people got hurt, but most injuries were not very serious.
The highway had to close for a while to clean up the mess.
This isn't the first time fog has caused problems on this road.
A similar but smaller crash happened a few weeks ago.
A 59-vehicle pile-up occurred on Highway 99 in Tulare County, California, due to thick fog.
Ten people were injured, with nine having minor injuries and one sustaining a moderate head injury.
The crash happened early Saturday morning, causing a complete shutdown of the highway for about six hours.
Visibility was reduced to between 100 and 200 feet due to dense fog, which was a key factor in the chain-reaction collisions.
The highway was fully reopened after approximately six hours, with lessons from a previous fog-related crash aiding in the response.
