How Safe Are Roller Coasters? What to Know After the Six Flags Incident

On October 12, 42-year-old Hassan Jihad Ibn Kariem went to Six Flags Over Georgia with his family to celebrate his niece’s birthday. Shortly before 4 p.m., he was ejected from the Goliath roller coaster — the park’s tallest ride — and fell to his death. Four other guests were injured. Kariem, described by his Atlanta charter school as a cherished member of their community, died at the scene.

The Cobb County Police Department’s Major Crimes Unit is investigating. Georgia’s Office of the Commissioner of Insurance and Safety Fire has opened its own inquiry. Six Flags temporarily closed nine similar roller coasters at parks across North America “out of an abundance of caution.” The company’s stock dropped 14% to its lowest level since 2009.

And millions of people who visit amusement parks every year are asking the same question: how safe is this, really?

The Numbers, First

Fatal roller coaster incidents are genuinely rare in the United States. The industry sees hundreds of millions of riders annually, and serious injuries — let alone deaths — represent a tiny fraction of that. According to the Global Association for the Attractions Industry, roller coasters accounted for 44% of amusement ride injuries in North America in 2024, but the vast majority of those were minor. By any statistical measure, driving to the theme park is more dangerous than riding the rides.

That context doesn’t make any individual tragedy less real. But it matters for understanding the safety architecture that exists around the industry.

How Roller Coasters Are Regulated

Here’s where American roller coaster oversight gets complicated: there is no single federal agency responsible for fixed-site amusement park safety. The Consumer Product Safety Commission handles mobile carnival rides, but permanent parks are regulated at the state level — and the quality and rigor of that oversight varies significantly.

States like New Jersey are known for some of the strictest requirements in the country, including comprehensive engineering reviews and frequent unannounced inspections. California requires annual inspections by qualified safety inspectors and conducts its own operational checks. Georgia’s oversight falls to the Office of the Commissioner of Insurance and Safety Fire — the same body now investigating the recent death.

Across all states, the technical standards themselves are largely set by ASTM International, a global standards organization. Its ASTM F24 committee has developed a comprehensive framework covering everything from ride design and manufacturing to installation, operation, and inspection. States can choose how rigorously to apply and enforce those standards, which is where the patchwork gets complicated.

What Happens Before You Board

The safety process for any given ride day starts long before the first guest arrives. Maintenance technicians perform pre-opening inspections each morning — cycling trains empty, checking restraint systems, testing brakes and controls, and verifying sensors before any rider boards. At major parks, these checks follow detailed checklists mandated by both operator standards and state requirements.

Six Flags, in a blog post published weeks before the Georgia incident, detailed its own procedures: daily inspections by maintenance and operations staff, reviews by outside inspectors, evaluations by corporate engineering teams, and employee training in safety procedures and emergency response. The company said its procedures are designed to meet or exceed manufacturer requirements and industry standards.

Beyond daily checks, rides undergo annual inspections by qualified third-party inspectors, and modern coasters are increasingly equipped with electronic monitoring systems — programmable logic controllers, sensor arrays, acoustic emission monitoring — that can detect anomalies in real time and halt operations automatically if something is wrong.

What Remains Unknown in Georgia

None of that context answers what happened on October 12. Investigators have not yet established whether the ejection resulted from a mechanical failure, a restraint issue, operator error, rider behavior, or some combination. Eyewitnesses described Kariem coming out of his seat and striking parts of the ride before falling — but the sequence of events that led to the ejection remains under active investigation.

What is known: the Goliath is a hypercoaster — 61 meters tall, significant speeds, substantial G-forces. Investigators will examine the restraint system that was in use, maintenance records, inspection logs, surveillance footage, operator actions, and physical evidence from the ride itself.

Six Flags said it supports the investigation and is cooperating fully with authorities.

What Riders Actually Control

One thing the industry consistently emphasizes: height, weight, and health restrictions on roller coasters are not suggestions. They’re engineering limits. Ride designers calculate restraint forces and structural loads based on specific parameters, and those parameters assume riders fall within the stated ranges. Guests who don’t meet the requirements — or who have conditions that make high G-force exposure medically risky — face real increased danger.

Beyond that, following all attendant instructions, ensuring restraints are properly locked and checked, and not attempting to exit or move during a ride covers most of what individual riders can do. The rest of the safety equation belongs to the engineers, manufacturers, inspectors, and park operators whose job it is to get every single train back to the station safely.

Most of the time, they do. When they don’t, the investigation into why matters — not just for accountability, but for the millions of riders who will visit parks again next weekend.
