The sign "Snow or ice glare" usually indicates that there may be slick conditions on the road due to the reflection of sunlight off snow or ice. This can cause a glare that reduces visibility and may make the road surface slippery.

Drivers should exercise caution when approaching areas where this sign is displayed. It is advisable to reduce speed, keep a safe distance from other vehicles, and be prepared for sudden changes in road conditions. Make sure to maintain control of the vehicle and avoid sharp maneuvers. Always stay alert for any additional signs or changes in the road that may accompany such conditions.
