💡 Low-Beam Lights
- Always use low beams in fog — high beams reflect off the fog and reduce visibility.
- If equipped, use fog lights (typically yellow and low-mounted) along with low beams.
🐢 Go Slow
- Fog can change rapidly — one moment it’s clear, the next it’s dense.
- Drive at a speed where you can stop within your visible distance.
- Use the right edge line (fog line) as a guide rather than the center line to avoid drifting into oncoming traffic.
🚨 Hazards in Extremely Dense Fog
- If the fog becomes too thick to drive safely, do not continue — pull off the road (parking lot, exit, or as far off the pavement as you can).
- Once stopped:
- Turn on your emergency flashers so others can see you.
- Wait for conditions to improve before getting back on the road.
- These conditions are rare but dangerous — better to wait it out than risk it.
🪟 Open a Window?
- Crack a window in thick fog to listen for cross traffic at intersections or curves where visibility is minimal.
🧘 Patience
- Some drivers may speed through fog — let them go.
- If you approach someone driving slowly, they may be doing so for good reason — follow at a safe distance unless it’s clearly safe to pass.
