Work Zones

Changing conditions related to work zones can challenge even the safest drivers. Work zone safety is important to IDOT. We understand that driving through work zones can be frustrating at times and we do our best to help protect your safety while you're getting to your destinations. Driving too fast or recklessly through a highway work zone is dangerous to your life and passengers and it is dangerous to highway workers laboring to improve roadways and further ensure your safety while driving.

We are all responsible for work zone safety, so please use caution and obey speed limits when driving through our work zones. And, remember, using handheld phones is illegal when driving anywhere in Illinois. Help us help you get there safely.

Please keep the following safety tips in mind when driving through work zones:

Slow down and always follow posted work zone speed limits. Reduced speeds are applied when normal conditions do not exist for the motorist (narrow lanes, changing conditions, edge drop offs). Posted speed limits throughout work zones are not a suggestion-they are the law! There is a Zero Tolerance policy against violations in work zones and fines have increased.

Pay attention. Workers and heavy equipment may only be a few feet from passing vehicles.
Be patient. Most of the time work zones require lane closures. Remain alert in case you need to slow down or stop due to traffic or construction work.
Follow the signs. Arrow boards and flaggers are not there to make your life more difficult, they are there to help guide you safely through the work zone.
Don’t follow too close. One of the most common crashes in a work zone is a rear-end
Turn on your headlights. Workers and other motorists driving through the work zone need to see your vehicle. Large truck operators should use emergency flashers to warn trailing motorists that they are slowing down.
Plan ahead. Leave a few minutes early when traveling through a work zone in order to reach your destination on time.
Drive smart and Embrace the Orange. See Orange. Slow Down. Save Lives
