Average monthly Colorado crashes, injuries, and fatalities compared with the modeled effect of a ten-cent gas-price increase.

Clearer crash-count signal

Colorado Gas Prices vs. Crashes

This study tests monthly Colorado gas prices against CrashStory crash counts, injuries, and fatalities. It is the stronger public-facing story because the crash-count relationship is materially clearer than the fatality relationship.

Timeframe

January 2023 to January 2026

Updated March 15, 2026. Output folder 2026-03-15.

Key read

176 fewer crashes

Comparison of estimated national fatality-rate effects across three model families.

Harder national reality check

National Gas Prices vs. Traffic Fatalities

This study pairs EIA gas prices with FARS fatalities and FHWA vehicle miles traveled across all 50 states and DC. It is intentionally stricter, and the answer stays much weaker and more model-sensitive.

Timeframe

2013 to 2023

Updated March 15, 2026. Output folder 2026-03-15.

Key read

-0.18%

estimated fatality-rate change from a 10% gas-price increase in the state-trend model

Context

551 observations

51 states and DC in the panel

80.4% of states lean negative year over year, but the overall fatality result is still weak.

Nationwide FARS Friday-the-13th fatal crash and fatality averages versus matched Friday controls.

Mixed superstition check

Is Friday The 13th More Dangerous To Drive?

CrashStory tests the myth directly. Colorado all-crash counts stay close to normal, while nationwide FARS fatal crashes lean modestly higher than matched Fridays.

Timeframe

Colorado January 1, 2013 to February 26, 2026. FARS 2013 to 2023.

Updated March 15, 2026. Output folder 2026-03-15.

Key read

+6.46%

nationwide fatal-crash change on Friday the 13th versus the other Fridays in those same months

Context

Colorado crash change in the same 2013 to 2023 overlap window

23 Colorado Friday-the-13th dates and 19 FARS dates make this a split verdict, not a myth-proof headline.

What this section is for

CrashStory research pages are not meant to be thin press-release pages. The goal is to give readers a human explanation of the finding, then make the supporting files easy to inspect.

Every study should answer four basic questions: what time period is covered, what sources were merged, what the main estimate means in plain English, and what the analysis cannot prove.

That is also why the national gas-price page exists alongside the Colorado page. The Colorado story is stronger, but the national reality check keeps the overall claim honest.
