Why Do These Accidents Happen?

Single-vehicle crashes like this one often stem from common roadway risks. According to the National Highway Traffic Safety Administration (NHTSA), motor vehicle accidents claim approximately 36,000 lives annually in the United States.

These statistics underscore the need for heightened awareness and adherence to traffic safety protocols. The Centers for Disease Control and Prevention (CDC) also highlights that rural highways like Interstate 15 pose unique dangers due to higher speeds and less frequent barriers.

Legal Insights

In cases such as this involving fatal single-vehicle accidents, a thorough independent investigation is crucial. Newsline's national legal analysts emphasize the importance of professional representation to navigate insurance claims effectively.

“Insurance companies frequently attempt to settle quickly for amounts far below the true value of a case, overlooking the profound long-term impacts on families,” said Candice Bond, managing partner at Bond Legal.

Key takeaways from insight analysis:

• Families may pursue wrongful death claims to cover funeral expenses, emotional distress, loss of companionship, and suffering.
• Such claims are civil actions distinct from any criminal proceedings.
• Passengers can file against the vehicle's insurance if the driver is deemed liable, without affecting personal policies.
• Experienced attorneys ensure fair compensation and respectful treatment throughout the process.

Stefano Formica, of counsel at Bond Legal, added:

“A wrongful death claim allows the estate or relatives to seek financial damages, providing some measure of justice in the wake of tragedy.”
