Navigating winter storms or severe flooding across the Hoosier State requires checking the official county status before you leave your driveway. Weather conditions can shift dramatically between northern lake-effect zones and southern river valleys. The Indiana Department of Homeland Security provides a centralized resource to track these changes in real time.
Understanding what each color level means on the map keeps you safe and helps you avoid legal trouble or stranded vehicles. Here's how to read the status system and plan your route effectively.
How the Indiana County Travel Status System Works
Unlike federal or state highway advisories that apply uniformly across major interstates, Indiana's emergency framework relies on local county control. Each county emergency management agency evaluates its own roads, bridges, and municipal streets. That means you can drive through a green or white county and suddenly cross into a red zone where travel is restricted.
The system uses specific color categories to communicate danger levels. Officials update these designations dynamically as storms develop or clear.
Advisory (Yellow)
A yellow advisory is the lowest level of local restriction. It means routine travel or activities may be restricted in certain areas because of a hazardous situation.
- What you should do: Exercise caution, reduce your speed, and allow extra stopping distance. Watch for slick spots on bridges and overpasses.
- Impact on daily life: Schools and local businesses may begin implementing their emergency action plans.
Watch (Orange)
An orange watch indicates that conditions are threatening to the safety of the public. Hazardous weather is actively impacting driving conditions, or an imminent threat has materialized.
- What you should do: Only essential travel is recommended. If you don't need to head out for work or an emergency, stay home.
- Impact on daily life: Employers often transition non-essential workers to remote setups, and municipal services scale back routine operations.
Warning (Red)
A red warning is the most severe designation issued by local authorities. It means travel may be restricted to emergency management workers only.
- What you should do: Refrain from all travel immediately. Comply with necessary emergency measures and local directives.
- Legal weight: In many Indiana counties, ignoring a red warning and getting stuck can result in traffic citations or fines because you put first responders at unnecessary risk.

Major Road Hazards Across the Hoosier State
Geography dictates how weather impacts Indiana roads. Driving habits that work well during a dry summer won't protect you when severe elements hit.
- Lake-Effect Snow: Northern counties near Lake Michigan frequently experience heavy, blinding snow squalls that drop visibility to near zero within minutes.
- Spring Flooding: Rivers like the Wabash, White, and Ohio often swell during heavy spring rains, submerging low-lying rural routes and county roads.
- Ice Storms: Central and southern regions are prone to freezing rain, which coats asphalt in a thin layer of black ice that standard winter tires struggle to grip.

Common Mistakes Drivers Make
Drivers often misinterpret how county advisories apply to their daily commutes. Avoiding these errors keeps you out of dangerous situations.
- Assuming statewide uniformity: Don't assume that because your home county is clear, your destination county is also clear. Always check every county along your intended route.
- Ignoring commercial vehicle rules: Commercial truck drivers must pay close attention to secondary road restrictions. Weight limits and travel bans apply heavily to freight haulers during orange and red alerts.
- Trusting GPS blindly: Standard navigation apps prioritize the fastest route, which often includes untreated secondary roads or county highways closed by local sheriff departments. Cross-reference your GPS route with the official travel map.
Frequently Asked Questions
Can I get a ticket for driving during a yellow advisory?
No. A yellow advisory is a warning to use caution, not a legal prohibition. However, if you drive recklessly or crash during an advisory, law enforcement can cite you for driving too fast for conditions.
How often is the travel map updated?
County emergency management directors update the map in real time. During major winter storms or severe weather outbreaks, the map changes 24 hours a day as conditions deteriorate or improve.
Where can I check road conditions by phone?
If you don't have mobile data access, you can call the Indiana Department of Transportation road conditions hotline at 1-800-261-7623 for automated updates.
What should I keep in my car during winter travel?
Always pack an emergency kit containing a charged mobile phone power bank, a flashlight, a warm blanket, bottled water, non-perishable snacks, a small ice scraper, and a bag of sand or kitty litter for traction if you slide off the road.
