The thick fog lingered through the day and across the valley, drivers did their best to deal. Some did a better job than others. California Highway Patrol spokesman Axel Reyes said drivers are still driving too fast. "That's when the collisions occur. And that's the message we've been trying to put out for years. Slow down," said Reyes.

The California Highway Patrol said in 100 feet visibility, the recommended safe speed is 26 miles per hour. At 200 feet, it's 43 miles per hour. Madera security guard Cory supple said drivers he sees during his overnight patrols don't seem to be getting the message. "When you get on the freeway, nobody is following that. They're going 65 miles per hour or better out there," said Supple.

The California Highway Patrol is also reminding drivers to make sure their headlamps are on during the dense fog. They said some drivers may not realize they're driving without lights because of their car's automatic headlight settings.
