Glendale Heights, IL – Drivers in Glendale Heights are being urged to use extra caution Wednesday morning as dense fog blankets the area, significantly reducing visibility during the early commute.
According to the Glendale Heights Police Department, a fog advisory remains in effect until 10:00 a.m. Wednesday, January 7, with visibility limited in some neighborhoods and on major roadways. Officers issued a reminder stressing that headlights must be turned on — not just daytime running lights — to ensure vehicles are visible from both the front and rear.
Police emphasized that many drivers mistakenly rely on automatic or daytime running lights during foggy conditions. While those lights may illuminate the road ahead, they often do not activate rear lights, making vehicles difficult to see for drivers approaching from behind.
The advisory applies across Glendale Heights in DuPage County, part of the western Chicago metropolitan area, where fog commonly forms during calm, humid winter mornings. Reduced visibility can increase the risk of rear-end crashes, especially at intersections, school zones, and highway on-ramps.
Authorities recommend slowing down, increasing following distance, and avoiding sudden stops. Drivers are also reminded to use low-beam headlights rather than high beams, which can reflect off fog and further impair visibility.
Morning commuters traveling through nearby suburbs and arterial roads connecting to larger routes should expect visibility to gradually improve as temperatures rise later in the morning.
Residents are encouraged to allow extra travel time and remain alert until conditions clear.
