Navigating the 2026 Central Valley Winter: Tips for Rain, Fog, and Beyond

At Ready Set Go Driving School, we want to make sure you’re prepared for whatever the 2026 winter season throws your way.

1. Mastering the Tule Fog

Dense fog in the Central Valley can reduce visibility to just a few feet. If you find yourself in a thick patch:

• Low Beams Only: Never use your high beams in fog; the light will reflect off the water droplets and create a "white wall" effect, making it harder to see.

• Use the "Fog Line": Focus on the solid white line on the right side of the road (the fog line) to help you stay in your lane.

• Listen: If fog is extremely dense, roll down your window at intersections to listen for oncoming traffic you may not be able to see.

2. Wet Road Realities

The first rain after a dry spell is the most dangerous because it mixes with oil and dust on the road to create a slippery film.

• Slow Down: The California "Basic Speed Law" states you must never drive faster than is safe for current conditions. Even if the sign says 65, 35 mph might be the safer choice during a heavy downpour.

• Increase Following Distance: In wet conditions, increase your following distance to at least five to six seconds to allow for longer stopping times.

3. Check Your 2026 Winter Gear

A quick vehicle check can prevent a major headache on the side of the road:

• The Quarter Test: Check your tire tread by inserting a quarter into the groove. If you can see the top of Washington’s head, it’s time for new tires.

• Wiper Blades: If your wipers are streaking, replace them immediately. You’ll need a clear view for those sudden January storms.

• Emergency Kit: Every car should have a winter kit including blankets, a flashlight with extra batteries, water, and jumper cables.

4. New 2026 Law Reminder: Move Over for Everyone

Remember that as of January 1, 2026, California's "Move Over" law has expanded. If you see any vehicle on the shoulder with its hazard lights flashing—whether it’s a Caltrans truck or a stalled car—you must move over a lane or slow down significantly. This is especially critical during low-visibility winter days.

5. Sierra Bound? Know Your Chains

If you're heading from Tracy toward the Sierras this winter, be aware of the 2026 chain requirements.

• Requirement 2 (R-2): Even if you have a 4WD vehicle with snow tires, you are still required to carry chains in your vehicle when entering chain control areas.

• Install Safely: Never stop in a traffic lane to put on chains. Wait until you see a designated "Chains Required" sign and pull completely off the roadway.
