Kentucky Road Conditions

To help prevent future work zone crashes, the Transportation Cabinet asks drivers to practice three work zone safety tips:


1. Pay Attention – Don't text, eat or perform any other activity while driving.
2. Respect Flaggers – Obey their guidance and watch their direction carefully.
3. Slow Down – Maintain a safe following distance; rear-end collisions are the
most common work zone crash.
