Intersection Crash Statistics

GITNUXREPORT 2026

Intersection Crash Statistics

Intersection crashes kill at a staggering scale and a surprising share of them trace back to specific failures at the signal and crosswalk, from 24,000 intersection-related fatalities in the United States (2018) to 66% of signalized-intersection crashes involving red-light running or signal violations (2020). This page connects the full picture to what actually reduces risk, including proven fixes like protected left turns, roundabouts, leading pedestrian intervals, and signal timing upgrades, so you can see exactly where safety gains are most likely to come from.

When nearly 3 million new light vehicles entered the U.S. in 2021 ready for connected communication, intersection crashes still remain stubbornly tied to everyday decisions drivers and pedestrians face at the curb. This post brings together the latest intersection crash statistics, from fatality shares and red light running to age, walking, and signal behavior, then pairs them with what safety countermeasures have actually reduced in the real world. The goal is simple to see where risk concentrates and why some fixes work far better than others.
