W Sahara Ave & S Decatur Blvd

Sahara and Decatur is a major surface street intersection in central-west Las Vegas where two of the valley’s highest-volume arterials meet. The intersection anchors a dense commercial area generating constant turn movements and driveway conflicts. Locals who live between the Strip and Summerlin cross this intersection constantly, and most have a specific memory of a close call here — the signal timing allows late left-turners to conflict with oncoming traffic that’s already moved on a fresh green.

What’s unusual here: injuries (112) exceed crashes (106) — indicating multi-vehicle T-bone collisions where both vehicles have multiple occupants. Zero fatalities across three years. Crashes spiked from 25 in 2022 to 45 in 2023 before settling to 36 in 2024. The hit-and-run rate of 11% is notably below the city-wide average — surface street intersections with cameras and witnesses are harder to flee than freeway ramps.
