Hurricane Season Car Accidents: Who's Liable When the Power Goes Out

Quick Summary

August is the heart of Atlantic hurricane season, and in Florida that means more than wind and rain. When the power goes out, traffic signals go dark, and most of the crashes that follow don't happen during the storm itself. They happen in the days after, when people are back on the road and intersections that normally run on green, yellow, and red have nothing at all.

Key Takeaways

• A dead traffic signal is legally a stop sign. Under Fla. Stat. § 316.1235, drivers approaching an intersection with an inoperative signal must stop, and where every approach is affected, it functions as an all-way stop. SOURCE: Fla. Stat. § 316.1235
• Most storm-related crashes happen after the storm passes, not during it. Once evacuation traffic clears and people return to normal routines, dark signals, downed debris, and flooded intersections create ongoing hazards that can last for days.
• Right-of-way at a dead signal follows the same rule as any four-way stop. First to stop goes first, and if two drivers arrive at the same time, the driver on the right has the right-of-way.
• A flashing red light and a flashing yellow light are not the same thing. Flashing red means stop, same as a dead signal. Flashing yellow means proceed with caution, no full stop required.
• Fault doesn't disappear just because the power was out. Insurance companies still investigate who had the right-of-way, and Florida's comparative negligence rule still applies to storm-related crashes the same way it applies to any other accident.

What the Law Actually Requires at a Dark Signal

Florida law doesn't leave this ambiguous. Under Fla. Stat. § 316.1235, when a traffic control signal is not functioning, drivers must stop before entering the intersection, the same as they would at a posted stop sign. When the outage affects every direction, which is the typical situation during a widespread power outage, that intersection functions as an all-way stop.

How Right-of-Way Works

• Come to a complete stop before the intersection, not just a rolling slow-down.
• The first vehicle to stop has the right to go first.
• If two vehicles arrive and stop at roughly the same time, the vehicle on the right generally has the right-of-way.
• Drivers turning left must yield to oncoming traffic going straight or turning right.
• Never assume another driver will stop just because the law requires it. Make eye contact where possible and proceed only when it's clearly safe.

Flashing Signals Aren't the Same as Dark Signals

A signal running on backup power sometimes shifts to a flashing pattern rather than going completely dark, and the two situations call for different responses. A flashing red light should be treated exactly like a dead signal: come to a complete stop. A flashing yellow light means proceed with caution, without requiring a full stop. Confusing the two, especially in low visibility after a storm, is a common cause of intersection crashes during hurricane season.

Why the Days After the Storm Are the Most Dangerous

It's easy to picture hurricane-related crashes happening during the worst of the wind and rain, but that's often not when the real risk shows up. Heavy rain, flooding, evacuation traffic, power outages, road debris, and post-storm stress can all increase the chance of a serious crash, and a lot of that risk plays out after the storm has already passed, once people are back on the roads while the infrastructure hasn't caught up yet.

A few patterns show up consistently after Florida storms:

• Dark and dead traffic signals at major intersections that normally run on a predictable rhythm, where drivers unfamiliar with the dead-signal rule blow straight through without stopping.
• Debris left in travel lanes, including downed limbs, blown-off roofing material, and displaced trash cans, that force sudden swerves or create obstacles drivers don't see in time.
• Flooded or partially flooded roadways, where a driver misjudges water depth, hydroplanes, or stalls in standing water and becomes a hazard to everyone behind them.

Each of these creates a different kind of crash, and each one raises different questions about who's actually at fault.

Storm season also raises the odds you'll be hit by a driver who can't cover your damages, whether from a lapsed policy or an out-of-state evacuee. → What to Do If the At-Fault Driver Has No Insurance in Florida explains your options if that happens to you.

How Fault Gets Determined in a Storm-Related Crash

A hurricane doesn't erase Florida's ordinary rules of the road, and it doesn't erase liability either. Insurance companies and courts still look at whether a driver followed the applicable traffic laws, including the dead-signal stop requirement, and whether their conduct was reasonable given the conditions.

Florida's modified comparative negligence rule still applies. Under Fla. Stat. § 768.81, if you're found more than 50% at fault for a crash, you can't recover damages, and below that threshold, your recovery is reduced by your percentage of fault. That means a driver who blew through a dead signal without stopping is going to have a hard time avoiding liability just because "the power was out," and a driver who did stop and was still hit by someone running the intersection has a strong position for recovery.

⚠️ Critical Warning: Insurance adjusters handling storm-season claims often try to characterize crashes as unavoidable "acts of nature." A dead traffic signal does not excuse a driver from stopping. Documenting exactly what the intersection looked like, and whether the other driver stopped, matters just as much in a storm-related crash as in any other.

The "act of nature" framing is just one tactic among several. → Common Insurance Mistakes After an Accident in Florida covers other patterns to watch for, storm-related or not.

What to Do If You're Driving Through a Power Outage

1. Treat every dark signal as a stop sign, no exceptions. Even if traffic seems to be moving through without stopping, that doesn't change your legal obligation or protect you if a crash happens.
2. Slow down before you reach the intersection, not at it. Reduced visibility and unfamiliar drivers mean you need extra time to react.
3. Watch for signals stuck on flashing red versus flashing yellow, and respond to each correctly rather than assuming both mean the same thing.
4. If it's unsafe or you're unsure, reroute. There's no rule that requires you to drive through an intersection you don't trust.
5. After a crash, document the signal status. Photograph the dead or flashing signal, note the time, and if possible get contact information for anyone else who witnessed the intersection's condition.

Frequently Asked Questions

Is a dead traffic light really the same as a stop sign in Florida? Yes. Fla. Stat. § 316.1235 requires drivers to stop at an inoperative signal, and when the outage affects the whole intersection, it functions as an all-way stop.

Who has the right-of-way when the light is out? The first vehicle to stop and arrive at the intersection generally goes first. If two vehicles stop at the same time, the vehicle on the right has the right-of-way.

Does hurricane season change any of the fault rules? No. The same traffic laws and the same comparative negligence rules apply. What changes is how often dark-signal situations come up, since outages are far more common during hurricane season.

What if the other driver says they didn't see the signal was out? Not seeing the outage isn't a legal excuse. Drivers are expected to treat an unresponsive signal as a stop sign regardless of whether they immediately realized why it wasn't working.

Can I still recover damages if I was partly at fault, like driving too fast through a dark intersection? Possibly. Florida's comparative negligence rule reduces your recovery by your percentage of fault rather than barring it outright, as long as you're not found more than 50% responsible.

Final Thoughts

Storms are unpredictable, but the legal rules that apply once the power goes out are not. A dead traffic signal is a stop sign under Florida law, full stop. The drivers who get hurt in these crashes are often the ones who did everything right and got hit by someone who didn't understand, or didn't care, that the rule still applied. If that happened to you, the storm doesn't get to be the excuse.
