Semi-truck driver accused of DUI after fatal crash in Las Vegas

A driver of a semi-truck is accused of driving under the influence after a fatal crash Monday morning in Las Vegas, according to police.

The Metropolitan Police Department said the crash occurred at about 10:35 a.m. in the area of West Washington Avenue and North Decatur Boulevard.

The Clark County coroner’s office said Tuesday that Peter Sampson III, 34, was killed in the crash.

According to police, the crash involved a Mack Anthem semi-truck pulling a trailer and a GMC Terrain. Police said it appeared that the GMC was heading east on Washington Avenue while speeding. At the same time, the semi-truck was exiting a private drive east of the intersection and heading west on Washington Avenue. The GMC then made contact with the left side of the semi-truck, police said.

The driver of the GMC was pronounced dead at the scene by medical personnel, according to Metro.

The driver of the semi-truck remained at the scene and was arrested after showing signs of impairment, police said.

Police said it was the 115th traffic-related death in Metro’s jurisdiction in 2025.

It was the second fatal crash that Las Vegas police investigated Monday. A person was killed in a separate crash earlier Monday morning in the south valley.
