Following a performance at Gus Stevens Supper Club in Biloxi, the group was driving a 1966 Buick Electra along U.S. Route 90 toward New Orleans for a television appearance.

The Fatal Crash: Debunking the Beheading Myth

The circumstances of the crash are crucial to understanding the true tragedy and the subsequent safety changes that followed. The accident occurred in the early hours of June 29, 1967, just east of the Rigolets bridge in Slidell, Louisiana.

The Vehicle and Occupants

The 1966 Buick Electra, driven by Ronald B. Harrison, was traveling behind a tractor-trailer. The truck, owned by a Mississippi company, was moving slowly and had reportedly slowed or stopped behind a truck spraying mosquito fogging insecticide, creating a thick, blinding cloud of fog on the highway.

The Buick, traveling at a high speed, slammed directly into the rear of the semi-trailer.

The Gruesome Reality vs. The Myth

The force of the impact was catastrophic. The front of the small car was completely wedged underneath the trailer, shearing off the top portion of the vehicle.

• The Victims: Jayne Mansfield, Samuel S. Brody, and Ronald B. Harrison, all in the front seat, were killed instantly due to massive head trauma.
• The Children: Remarkably, the three children—Mariska Hargitay (age three), Miklós Jr., and Zoltán—were asleep in the back seat and survived the crash with only minor injuries.

The Beheading Myth: The most persistent and sensationalized detail of the accident is the widely circulated rumor that Jayne Mansfield was decapitated. This is false. The myth likely originated from a police report describing a severe head injury and the fact that the top of the car was sheared off. Furthermore, the actress's distinctive blonde wig was reportedly found outside the vehicle, leading to further misinterpretation and fueling the morbid rumor. The official cause of death for Mansfield was a "crushed skull with avulsion of cranium and brain."

The Mansfield Bar: Jayne Mansfield’s Life-Saving Legacy

While her life was tragically cut short, Jayne Mansfield's death was not in vain. The horrific nature of the accident—specifically the way the car slid completely underneath the semi-trailer—shocked the public and prompted a significant change in vehicle safety regulations.

The Underride Guard Mandate

The accident highlighted a critical design flaw in semi-trailers: the lack of a strong rear barrier to prevent smaller vehicles from sliding underneath in a rear-end collision. This type of accident, known as an "underride collision," is often fatal to the occupants of the smaller vehicle, as the truck's chassis crushes the passenger compartment.

In 1969, the National Highway Traffic Safety Administration (NHTSA) proposed a new federal regulation that would require a strong, steel bar to be installed on the rear of all semi-trailers. This bar is designed to prevent a car from going underneath the truck in a crash, forcing the impact to be absorbed by the car's frame and crumple zone.

A Name That Stuck

Though officially called an "underride guard" or "rear impact guard," the safety device is still informally and widely known in the trucking and safety industries as the "Mansfield Bar" (or sometimes a "DOT bumper"). This enduring nickname serves as a permanent, albeit tragic, memorial to the actress. The regulation, which took full effect in the early 1990s, is credited with saving countless lives on highways across the country by mitigating the severity of underride collisions.

The legacy of Jayne Mansfield, therefore, extends far beyond her iconic Hollywood image. It is a legacy of safety, a constant reminder of the tragic night that led to a major, life-saving change in federal vehicle standards. Her daughter, Mariska Hargitay, has gone on to become a major star and humanitarian, ensuring the Mansfield name remains a powerful force in the public eye, often speaking about her mother's enduring impact.

The true story of Jayne Mansfield's death is not just about a sensational car crash; it's about the profound, unexpected way a single tragedy can spark a change that benefits millions. While the glamour and tragic end of the starlet are what history remembers, the Mansfield Bar is the quiet, steel-enforced testament to her lasting, life-saving contribution to public safety.
