O TruckingHow to Report Road Hazards: Trucker
Key Takeaways
- CB channel 19 is the fastest warning — broadcast direction, highway, hazard, lane, and mile marker so nearby drivers can react.
- Dial 911 or your state highway patrol shortcode (*HP, *FHP, *47) for anything blocking a lane, causing crashes, hazmat spills, or animals in traffic.
- Use 511 or your state DOT maintenance hotline for non-emergency debris, road gators, and potholes that need a crew dispatched.
- You are not legally required to report a hazard you spot, but you may be liable if your own truck created the debris and you leave the scene.
- Apps like Waze and Trucker Path let you both report and view driver-sourced hazards in real time.
Reporting Methods: Fastest to Most Official
1. CB Radio (Channel 19) — Immediate Warning
The fastest way to warn nearby truckers about a road hazard. CB radio alerts reach drivers within a 5-15 mile radius instantly — faster than any other method. If you are new to the radio or need a refresher on clear hazard calls, see our emergency CB procedures guide.
Format: “[Direction] [Highway], [hazard description] in the [lane] at mile marker [number].”
Example: “Northbound I-81, big gator in the hammer lane at mile marker 215. Watch your tires, drivers.”
When to use: Every hazard you spot. Even small debris deserves a CB call — it takes 5 seconds and could prevent an accident.
2. 911 or *HP — Emergency Hazards
Call 911 or your state's highway patrol shortcode (*HP in many states) for hazards that pose immediate danger:
Large objects blocking a travel lane (furniture, cargo, large tire debris)
Debris that has already caused an accident or near-miss
Hazardous material spills or leaking vehicles
Animals on the highway (live or recently hit in a travel lane)
Use Hands-Free When Calling While Driving
3. State DOT Hotlines — Non-Emergency Reports
For non-emergency debris (single road gator, small debris on the shoulder, potholes), call your state's DOT highway maintenance hotline. These calls dispatch maintenance crews to clear the hazard.
| State | Highway Hotline | Notes |
|---|---|---|
| Texas | 1-800-452-9292 | TxDOT 24/7 hotline |
| California | 1-800-427-7623 | Caltrans Road Conditions |
| Florida | 511 or *FHP | FL Highway Patrol |
| Georgia | 511 or 1-877-694-2511 | GDOT |
| Most States | 511 | National travel info number |
4. Mobile Apps and Online Reports
Several apps allow truckers to report and view road hazards reported by other drivers:
Waze — Community-based hazard reporting with real-time alerts from other drivers. Widely used by both truckers and four-wheelers.
Trucker Path — Trucker-specific app with road hazard reporting, weigh station status, and truck stop information.
State DOT apps — Many state DOTs have mobile apps for reporting road conditions and hazards directly to maintenance dispatch.
Build the Habit of Always Reporting
What to Do If You Caused the Hazard
Reporting a hazard you spot is optional. But if the hazard came from your truck — a blown tire that left a road gator, a load that shifted and dropped debris, or a fluid leak — your responsibilities change. Leaving the scene of a hazard you created can expose you to negligence liability if it damages another vehicle, and in some states it can rise to a criminal charge.
Get safe first. Pull fully onto the shoulder, turn on hazards, and deploy your warning triangles per the FMCSA spacing rule before doing anything else.
Warn traffic immediately. Put out a CB call on channel 19 so following drivers know debris is in the lane, then call 911 or the state highway patrol if it is blocking traffic.
Notify your carrier or dispatcher. They can log the incident, coordinate cleanup, and start any insurance or claims paperwork.
Document the scene. Photos of the debris, your equipment, and the location protect you if another driver later files a claim.
The best fix is prevention. Most trucker-caused road debris is a tire or cargo problem, so review our guides on preventing tire blowouts, avoiding road gators, and FMCSA cargo securement to keep your equipment off the roadway in the first place.

Road Hazard Reporting FAQ
Common questions about reporting road hazards, debris, and safety concerns
Should I call 911 for road debris?
Call 911 for road debris that poses an immediate danger to traffic — large objects blocking a lane, debris that has already caused an accident, or hazardous material spills. For non-emergency debris like a single road gator on the shoulder or small debris in the breakdown lane, use your state's DOT highway maintenance hotline instead. Most states also have a *HP (Highway Patrol) shortcode that connects you directly to the state police dispatcher.
How do I report road hazards on CB radio?
Report road hazards on CB channel 19 (the trucker highway channel) using this format: direction, highway name, hazard description, lane, and mile marker. Example: 'Northbound I-81, big gator in the hammer lane at mile marker 215.' Keep the report brief, specific, and factual. Do not speculate about causes — just describe what you see and where it is. This helps other drivers prepare for the hazard.
What information do I need to report a road hazard?
To make an effective road hazard report, you need: (1) Highway name and direction (e.g., I-40 westbound), (2) Mile marker or nearest exit number, (3) Which lane the hazard is in (left/right/center/shoulder), (4) Description of the hazard (tire debris, fallen cargo, animal, ice, etc.), (5) Size and severity (small debris vs large object blocking a lane), (6) Whether any accidents have resulted. Having this information ready before you call makes the report faster and more useful.
Can I get in trouble for not reporting a road hazard?
There is no federal or state law that requires you to report a road hazard (you are not legally obligated). However, if you caused the hazard — for example, your tire blew out and created a road gator, or cargo fell from your trailer — you may have a legal obligation to stop and address the situation. Leaving the scene after creating a road hazard that damages other vehicles can result in liability for negligence or even criminal charges in some jurisdictions.
What number do I call to report a road hazard or debris?
For an emergency — debris blocking a lane, a crash, a hazmat spill, or animals in traffic — dial 911 or your state highway patrol shortcode (*HP, *FHP, *47, etc., depending on the state). For non-emergency debris, potholes, or shoulder hazards, dial 511, the national travel-information number, which routes to your state DOT, or call your state DOT's dedicated maintenance hotline. When in doubt, 911 dispatchers will redirect you to the right agency.
What is the 511 road hazard reporting number?
511 is the nationwide traveler-information phone number operated by state departments of transportation. Dialing 511 from most U.S. states connects you to live road-condition information and, in many states, lets you report hazards like debris, potholes, or stalled vehicles to maintenance dispatch. It is free, hands-free friendly, and the simplest non-emergency option when you do not know your state's specific DOT hotline.
