What Are Rollover Accidents and Why Do They Happen?

January 6, 2026

Rollover accidents are crashes in which a vehicle flips onto its roof or side. Sometimes, the vehicle rolls several times. The vehicle and its occupants experience an initial impact, followed by repeated impacts as the vehicle rolls. Additionally, vehicle occupants may be fully or partly ejected from the vehicle during these crashes. As a result, rollover accidents often cause severe injuries or fatalities.

If you or a loved one has been involved in a rollover, working with a Lexington car accident lawyer can help you understand your legal rights and options for compensation.

What Are Rollover Accidents and Why Do They Happen?

Types of Rollover Accidents

The National Highway Traffic Administration (NHTSA) has conducted extensive research into rollover crashes. It observes that these accidents are complex events involving interactions between drivers, road conditions, vehicles, and the environment. The NHTSA distinguishes between “tripped rollovers” and  “untripped rollovers.

Tripped Rollover Accidents

In tripped rollover accidents, a vehicle begins to roll after striking a curb, guardrail, the soft shoulder of a road, or some other obstacle at the edge of a road. Most of the 8% of vehicle accidents that result in rollovers are tripped rollovers.

Untripped Rollovers

Untripped rollovers are less common than tripped rollovers. They occur when a vehicle’s speed, momentum, and the way a driver steers cause a rollover without it striking some other object. Excessive speed and swerving can cause untripped rollovers, particularly when a vehicle’s design makes it top-heavy.

Causes of Rollover Accidents

According to the NHTSA’s findings, most rollover crash fatalities occurred in single-vehicle rollover accidents. However, some fatalities were associated with rollover crashes in which two or more vehicles were involved.

As previously noted, several factors may simultaneously contribute to any rollover crash. This is particularly true in single-vehicle rollovers, where driver behavior, vehicle-related factors, and environmental conditions can combine, resulting in tragic consequences.

Driver behaviors contributing to a rollover crash include:

  • Speeding when navigating curves
  • Steering overcorrections or swerving
  • Distracted or aggressive driving
  • Driver impairment due to fatigue or substance use

Vehicle-related factors include:

  • Vehicles with a high center of gravity, e.g., SUVs and trucks
  • Tire blowouts or underinflated tires
  • Mechanical faults affecting brakes, steering, or suspension
  • In trucks, improper loading or overloading

Environmental factors associated with rollovers may include:

  • The presence of obstacles or debris that cause “tripping”
  • Strong winds, particularly when a vehicle has a high center of gravity
  • Uneven or slippery road surfaces

Finally, rollovers can result from collisions between vehicles, particularly in T-bone (side-on) accidents at dangerous intersections or when an impact forces a vehicle into an obstacle like a curb or guardrail.
