S Rainbow Blvd & W Charleston Blvd

Rainbow and Charleston is a major surface street intersection in the western residential neighborhoods — between Summerlin and Spring Valley. This is a local intersection, not a tourist one: the people crashing here are residents going about their daily lives. The intersection anchors a dense shopping area with constant turn movements and pedestrian activity, and the permissive left-turn signal phase here allows enough late movement to conflict with oncoming cross-traffic that’s already moved on a fresh green.

Injuries (94) nearly matching crashes (92) indicates T-bone and angle collisions where both vehicles have occupants. Zero fatalities. The crash count has been declining: 35, 34, 23 in 2024 — a 34% reduction representing genuine improvement. The hit-and-run rate of 10% is notably low, reflecting the well-witnessed surface street environment with cameras and bystanders. This is a positive data point for this intersection.
