Why Do Rear-End Crashes Happen So Frequently?

Rear-end collisions account for a substantial portion of traffic incidents nationwide. According to the National Highway Traffic Safety Administration (NHTSA), these crashes represent nearly 29% of all U.S. collisions.

Common contributing factors include:

• Distracted driving, such as texting or adjusting devices.

Legal Insights

In cases such as this involving motor vehicle crashes, independent reviews play a crucial role in uncovering the full circumstances.

“In addition to the diligent work of law enforcement, an attorney can re-interview important witnesses, analyze any surveillance video from the scene of the crash, and obtain phone and texting records of the liable party,” said Candice Bond, managing partner at Bond Legal and a national analyst for Newsline.

Key takeaways from legal perspectives on these incidents:

• Time is critical, and evidence must be preserved quickly to support investigations.
• Families may pursue claims for wrongful death, covering losses like companionship and emotional distress.
• Consulting professionals ensures comprehensive analysis beyond initial police reports.

“We understand that losing a loved one is not only a deeply emotional loss but also an economic one,” said Stefano Formica, of counsel with Bond Legal. “If you have lost a loved one due to someone else’s negligence, contact a wrongful death attorney and get the guidance needed to obtain the justice you deserve.”
