You're driving down I-65. It's February. The sky looks like a bruised plum and suddenly, the rain turns into that heavy, wet slush that makes your windshield wipers scream. You wonder if the county line you just crossed is under a "Red" warning or if it’s just a "Yellow" advisory. This is where the travel advisory map of Indiana becomes your best friend. Honestly, most people don't even know this map exists until they’re already fishtailing into a ditch near Lafayette. That's a mistake.
The map isn't just for blizzards.
It’s a real-time data visualization managed by the Indiana Department of Homeland Security (IDHS). It breaks the state down by county, using a color-coded system that tells you exactly how much trouble you're in if you decide to go out for a gallon of milk. But it’s not always about snow. Flooding, high winds, or even massive infrastructure failures can trigger these changes. Understanding what "Orange" actually means versus "Yellow" could literally save your life—or at least save you from a very expensive tow truck bill.
The Color Code: What the Travel Advisory Map of Indiana Actually Means
If you look at the map right now, it’s probably mostly white. That’s the goal. White means "Normal." No travel restrictions are in place. But Indiana weather is moody. Within three hours, a county can shift through the entire spectrum.
Yellow: Advisory
This is the lowest level. It’s basically a "heads up." The IDHS says that routine travel or activities may be restricted in certain areas because of a hazardous situation. You can still go to work. You can still go to the gym. But you should probably slow down. It’s the state’s way of saying, "Hey, things are getting a bit dicey, so don’t be a hero."
Orange: Watch
Now we’re getting serious. When a county on the travel advisory map of Indiana turns orange, it means conditions are threatening to the safety of the public. Only essential travel is recommended. Think: going to work, picking up medicine, or fleeing a dangerous situation. If you’re just headed to the movies, maybe stay home. During an Orange Watch, local officials are usually coordinating with emergency management because the roads are deteriorating fast.
Red: Warning
The "big one." Red is the highest level of local travel advisory. It means travel is strictly restricted to emergency management workers and those responding to the disaster. If you are caught driving in a Red county without a valid emergency reason, you’re not just being risky—you might actually be breaking local ordinances. In many Indiana counties, a Red Warning means the roads are officially closed to the general public.

Why the Map Isn't Always Perfect
Here is something nobody tells you: the map is updated by individual county emergency management agencies (EMAs). This means there can be a "lag." You might be driving through a county that feels like a frozen tundra, but the map still shows it as White or Yellow because the local director hasn't pushed the update to the state server yet.
It’s a decentralized system.
It relies on humans. Humans who are often out in the field measuring snow drifts or checking bridge stability. So, while the travel advisory map of Indiana is the gold standard for official status, you still have to use your eyes. If the road looks like a skating rink, treat it like a Red zone, regardless of what your phone screen says.
The Role of the IDHS and Local Law Enforcement
The Indiana Department of Homeland Security doesn't just make these calls from a dark room in Indianapolis. It’s a collaborative effort. They take reports from the National Weather Service, the Indiana State Police (ISP), and local highway departments.
I remember a specific storm in 2021 where Hamilton County was under a Watch while neighboring Marion County stayed under an Advisory. The difference? A lake-effect band that decided to park itself right over the northern suburbs. The map reflected that granular detail. That’s the beauty of it. It’s not a "one size fits all" for the whole state. It’s hyper-local.
How to Access the Map on the Fly
Don't wait until you lose cell service to try and find the link. The easiest way to keep tabs on this is through the official IDHS website or the "Indiana Travel Advisory" app. Yes, there’s an app for it. It’s available for both iOS and Android.

- Download the app before winter hits.
- Enable notifications for the counties you frequently travel through.
- Check the "County Comments" section. This is a pro tip. Sometimes, the EMA director will leave a specific note like "Trees down on Highway 421" or "Flooding near the Wabash River." These notes provide context that a simple color can't convey.
The app also links directly to the Indiana Department of Transportation (INDOT) cameras. If you see a county is Orange, you can jump over to the INDOT "Cars" map and actually see the live camera feed of the highway. Seeing the slush with your own eyes is a great reality check.
Common Misconceptions About Indiana Travel Advisories
A lot of people think a "Travel Warning" (Red) is the same as a "Travel Ban." In Indiana, the terminology is specific. While the governor can technically issue state-wide mandates, these county-level advisories are local. However, insurance companies often look at these levels. If you get into a wreck in a Red county while you were out buying a lottery ticket, your insurance provider might have some very pointed questions about why you were on the road against official emergency advice.
Another myth? That these maps are only for snow.
In the southern part of the state, particularly near the Ohio River, the travel advisory map of Indiana turns colors quite often in the spring due to flash flooding. Heavy rains can wash out culverts and turn backroads into rivers in minutes. The map tracks these "Environmental Hazards" just as diligently as it tracks a blizzard.
Real-World Impact: The 2022 Christmas Eve Blizzard
Let’s talk about a real scenario. December 2022. A massive "bomb cyclone" hit the Midwest. Indiana saw temperatures drop 30 degrees in a matter of hours. The map was a sea of Red.
In that instance, the ISP was pleading with people to stay off I-65 and I-70. Because people checked the travel advisory map of Indiana and saw the Red warnings, thousands stayed home. This kept the roads clear for salt trucks and emergency vehicles to reach people whose furnaces had failed in sub-zero temps. It’s about the "system" working together. When you stay off the road during an Orange or Red advisory, you’re literally helping a snowplow driver do their job faster.

Navigation Apps vs. Official State Maps
Waze is great for finding speed traps. Google Maps is great for finding the fastest route to a Taco Bell. But they aren't emergency management tools. Google Maps might show a road is "red" because of traffic, but it doesn't tell you why that traffic is there. It could be a 50-car pileup because of black ice.
The travel advisory map of Indiana gives you the "why." It tells you the legal and safety status of the region. Always cross-reference. If Google says a route is clear but the IDHS map says the county is under a "Watch," trust the state. They have the boots on the ground.
Preparing Your Vehicle for "Orange" and "Red" Conditions
If you absolutely must travel during a high-level advisory—maybe you're a nurse or a first responder—the map should be your cue to double-check your emergency kit.
- Check your tire pressure. Cold air makes it drop.
- Full tank of gas. If you get stuck for six hours, you need the heat.
- Physical blankets. Not just a light jacket.
- External battery pack. Your car battery might die if the alternator fails in the cold.
- Cat litter or sand. For traction if you get stuck in a drift.
Actionable Steps for Indiana Travelers
Don't just bookmark the map and forget it. Integrate it into your winter routine.
First, go to the IDHS website and look at the current map. Familiarize yourself with the layout. Notice how the counties are clustered. Often, you'll see a trend moving from the northwest (near Chicago) down toward the southeast. This is the typical path of "Clipper" systems.
Second, if you're planning a trip from, say, Indianapolis to Fort Wayne, check every county along that route. Allen County might be White, but Grant or Howard County could be Orange. You don't want to hit a wall of snow halfway through your trip.
Third, use the "History" feature if you're a data nerd. You can see how often certain counties go into Red status. This is actually pretty useful if you're looking at moving to a new area or planning a regular commute. Some counties are just better at clearing roads than others, often due to budget or equipment availability.
Finally, remember that the travel advisory map of Indiana is a living document. It changes. During a major event, refresh it every 30 minutes. The situation on the ground in a "lake effect" zone can change from "clear skies" to "zero visibility" in the time it takes to finish a cup of coffee. Stay informed, stay off the roads when the map turns Red, and always keep a bag of salt in the trunk. It’s just the Indiana way.
