Without daily exposure data, neither dataset proves that the average trip is inherently riskier."],"limitations":["CrashStory Colorado data measure reported crash totals and severity mix, not traffic exposure or miles driven.","The public CrashStory daily totals show a visible level shift beginning in 2023, so the Colorado page uses matched Friday controls and an overlap-window sensitivity check rather than a single long-run raw average.","FARS only covers fatal crashes and fatalities. It cannot answer whether all crashes or minor injury crashes behave the same way nationwide.","The FARS comparison is nationwide and daily, but it still does not include daily VMT or trip counts, so it cannot prove per-trip risk.","The news examples section is anecdotal by design. It shows how Friday-the-13th crash coverage gets framed, not how often those crashes happen relative to normal Fridays."],"sourceLinks":{"CrashStory research hub":"https://crashstory.com/research","NHTSA FARS overview":"https://www.nhtsa.gov/research-data/fatality-analysis-reporting-system-fars","FARS 2023 national CSV zip":"https://static.nhtsa.gov/nhtsa/downloads/FARS/2023/National/FARS2023NationalCSV.zip","Cranbrook Daily Townsman story":"https://cranbrooktownsman.com/2026/03/15/boulder-hits-semi-driver-on-highway-1-near-revelstoke/","WISN Friday the 13th Wausau story":"https://www.wisn.com/article/friday-the-13th-near-death-crosswalk-crash-in-wausau/65063510","Daily Voice Paramus Friday the 13th story":"https://dailyvoice.com/new-jersey/cresskill/friday-the-13th-chaos-dump-truck-crash-car-into-gym-rock-paramus-morning/","Hudson Valley Post Friday the 13th train story":"https://hudsonvalleypost.com/photos-car-drives-into-train-on-friday-the-13th-in-hudson-valley/"},"artifacts":["C:\\repos\\crashstory-platform\\docs\\research\\outputs\\friday-the-13th-risk\\2026-03-15\\colorado-friday-13th-comparisons.csv","C:\\repos\\crashstory-platform\\docs\\research\\outputs\\friday-the-13th-risk\\2026-03-15\\colorado-friday-13th-comparisons.json","C:\\repos\\crashstory-platform\\docs\\research\\outputs\\friday-the-13th-risk\\2026-03-15\\colorado-friday-13th-comparisons-overlap.csv","C:\\repos\\crashstory-platform\\docs\\research\\outputs\\friday-the-13th-risk\\2026-03-15\\colorado-friday-13th-comparisons-overlap.json","C:\\repos\\crashstory-platform\\docs\\research\\outputs\\friday-the-13th-risk\\2026-03-15\\fars-friday-13th-comparisons.csv","C:\\repos\\crashstory-platform\\docs\\research\\outputs\\friday-the-13th-risk\\2026-03-15\\fars-friday-13th-comparisons.json","C:\\repos\\crashstory-platform\\docs\\research\\outputs\\friday-the-13th-risk\\2026-03-15\\friday-the-13th-news-examples.json","C:\\repos\\crashstory-platform\\docs\\research\\outputs\\friday-the-13th-risk\\2026-03-15\\future-friday-13ths.json","C:\\repos\\crashstory-platform\\docs\\research\\outputs\\friday-the-13th-risk\\2026-03-15\\chart-colorado-friday-13th-vs-controls.png","C:\\repos\\crashstory-platform\\docs\\research\\outputs\\friday-the-13th-risk\\2026-03-15\\chart-colorado-friday-13th-relative-difference.png","C:\\repos\\crashstory-platform\\docs\\research\\outputs\\friday-the-13th-risk\\2026-03-15\\chart-fars-friday-13th-vs-controls.png","C:\\repos\\crashstory-platform\\docs\\research\\outputs\\friday-the-13th-risk\\2026-03-15\\chart-fars-friday-13th-relative-difference.png","C:\\repos\\crashstory-platform\\docs\\research\\outputs\\friday-the-13th-risk\\2026-03-15\\friday-the-13th-risk-report.json","C:\\repos\\crashstory-platform\\docs\\research\\outputs\\friday-the-13th-risk\\2026-03-15\\friday-the-13th-risk-report.md"]}}}
