Avoid driving during the 6:00 AM – 9:00 AM window when patchy fog, freezing fog, and black ice pose the greatest hazard. If you must drive in the morning, slow down, use low-beam headlights, and allow extra stopping distance. Safe morning window: 10:00 AM – 11:00 AM, once fog has fully cleared and temperatures are above freezing. Safe evening window: 5:00 PM – 7:00 PM, while temperatures are still in the mid-to-upper 40s, skies are mostly clear, and winds remain light. Late-night drivers (after 11 PM) should exercise caution as temperatures approach freezing again.
