69-Vehicle Fog Pileup on I-95 in South Carolina: Weather Is Not an Excuse, and Other Insurance Lessons

By AutoInsuranceBundle.pro · Published October 29, 2026

Fog changes everything about a drive in a matter of seconds. One moment you can see half a mile ahead, the next you can barely see the car in front of you. That is what drivers on a South Carolina bridge faced on the first morning of October.

The pileup on the Lake Marion bridge

On Thursday morning, October 1, 2026, dense fog reduced visibility on the Interstate 95 bridge over Lake Marion in Clarendon County. According to NBC 6, citing its affiliate WIS 10, what began as a smaller crash quickly grew into a chain-reaction pileup involving 69 vehicles, including passenger cars and commercial trucks.

Clarendon County Fire Rescue reported that two vehicles needed mechanical extrication to free trapped occupants, and one person was airlifted to a hospital. Several others were hurt. Traffic was so jammed that some crews walked to reach injured motorists. Southbound lanes stayed closed for hours and reopened early the next day. The South Carolina Highway Patrol is investigating.

Why "it was the fog" rarely settles a claim

Some drivers assume that weather makes a crash nobody's fault, a so-called act of God. Insurers and courts generally don't see it that way. Traffic laws in every state require driving at a speed that is reasonable for conditions. When visibility drops, the expectation is that drivers slow down, increase following distance, and use low-beam headlights.

So in a fog pileup, each impact is usually evaluated on its own:

• Did the driver behind leave enough room to stop within the distance they could see?
• Was a vehicle stopped in a travel lane without lights?
• Did someone change lanes into a gap that wasn't there?

A driver who was hit from behind while stopped may have little or no fault. A driver who plowed into stopped traffic at highway speed may carry most of it, even though fog was the reason traffic stopped.

We covered how chain-reaction crashes are untangled generally in our article on the I-75 chain-reaction crash in Georgia. The fog adds one more layer: the "too fast for conditions" question.

South Carolina's rules in brief

South Carolina is an at-fault state that uses a form of modified comparative fault: in general, an injured person can recover damages as long as they are not more at fault than the party they're claiming against, with their award reduced by their share of fault. Minimum liability limits are $25,000 per person, $50,000 per accident, and $25,000 for property damage, and uninsured motorist coverage is required, according to the Insurance Information Institute. In a crash involving dozens of vehicles, those minimum limits can be used up quickly, especially when several people claim against the same driver.

Commercial trucks carry federal minimum liability coverage far above personal auto minimums, which can matter when a truck is part of the chain.

If you get caught in fog

While driving

• Slow down gradually and keep plenty of distance.
• Use low beams and fog lights. High beams reflect off fog and make visibility worse.
• Use the right edge line as a guide, not the taillights ahead.
• Don't stop in a travel lane. If you must stop, pull completely off the road, turn on hazards, and take your foot off the brake so drivers don't follow your lights.

After a crash

1. Decide quickly whether staying in the car is safer than leaving it. In a pileup, more vehicles may keep arriving. If you can get well off the road and away from traffic, that is often safer.
2. Call 911 with your location, such as the bridge, mile marker, or direction.
3. Document what you can once safe: vehicles directly in front of and behind you, damage to front and rear, and visibility conditions.
4. Exchange information with the drivers immediately ahead and behind. Note the drivers' names, insurers, and plates; for trucks, note the company name and DOT number on the door.
5. Report the claim to your insurer the same day. Large pileups mean many claims, and early notice helps.

How insurance tends to handle a pileup

Expect several insurers to be involved and fault to be shared among multiple drivers. Your collision coverage can repair your car while that process plays out, with your insurer seeking repayment from others later. PIP or MedPay, if you have it, and health insurance can pay medical bills early. If the driver who hit you doesn't have enough coverage, underinsured motorist coverage may help.

Mistakes to avoid in a weather-related crash

• Assuming nobody is at fault. Insurers still assign responsibility.
• Only documenting the front of your car. In a chain reaction, rear damage matters just as much.
• Waiting for the police report before you notify your insurer.
• Forgetting the trucking company's name, which is often more useful than the driver's name.

Is your auto coverage ready for a bad-weather day?

Fog, rain, and smoke don't give much warning. Liability limits above the state minimum, collision coverage, and UM/UIM give you more room when a crash involves many vehicles. Compare quotes with a licensed agent in one free call at (888) 217-5854.

FAQ

Is a crash in fog considered no-fault?

Not in the sense most people mean. "No-fault" refers to how injury claims are paid in certain states. In fog, drivers are still expected to drive safely for conditions, and fault can still be assigned.

Who pays in a multi-car pileup?

Usually the insurers of the drivers who caused each impact, often in shared percentages. Your own collision coverage can pay first and recover later.

Should I stay in my car during a pileup?

It depends on the situation. If more vehicles may strike yours and you can safely get well away from the roadway, many safety officials advise leaving the car. Follow instructions from first responders.

Can I be partly at fault if I was hit from behind?

Possibly, if you stopped suddenly without reason or were stopped in a lane without lights. Each impact is assessed separately.
