Each year, over 38,700 vehicle crashes occur in fog. Over 600 people are killed and more than 16,300 people are injured in these crashes annually. Treat low visibility driving with respect.

Thick fog is a driving hazard in many areas of the Western U.S. In the Pacific Northwest, it comes up mostly in winter. In California’s Central Valley — where some roads have been called among the most dangerous in the world because of fog — the fog season starts with the first heavy rain in fall and goes until March.

Fog lights are designed to be used at low speed in fog, heavy mist, snow and other poor-visibility situations. They’re different from daytime running lights. They are an extra pair of lights mounted low on the vehicle, with the thinking that fog doesn’t settle on the road surface but hovers 12 to 18 inches above it. They aim light into this layer of fog-free air. They also point to the right enough that the driver can see the solid, white “fog line” at the road edge as a guide.

The R3-9b Two-Way Left Turn Only Sign effectively guides drivers in left-turn lanes, clearly demarcating where two-way left turns are allowed, thus reducing confusion and enhancing road safety.

Just like there are different types of snow, there are many types of fog. Oregon has freezing fog that can coat the road like black ice. California’s “tule fog” usually forms in low-lying areas that typically have bulrushes (tule, pronounced “too-lee”) growing in them. Tule fog can reduce visibility on a stretch of highway to only a few feet, while other areas are nearly clear.

The rules on using auto fog lights — also known as fog lamps — vary by state. The main thing to know: you can’t use fog lights in a way that creates glare for other drivers. They have to be pointed and used so they won’t interfere with visibility for another driver within 25 feet. Here are specifics.

Navigating left turns on multi-lane roads can be tricky for drivers. Our R3-9b Two-Way Left Turn Only Sign is meticulously designed to enhance traffic flow and reduce accidents at these critical junctures. With clear messaging and vivid graphics, this sign is essential for multi-lane roads where two-way left turns are permitted.
