• U.S. traffic fatalities declined by an estimated 8% year-over-year in the first half of 2025, reaching the lowest level for the period since 2020.
  • The fatality rate per 100 million vehicle miles traveled (VMT) also fell significantly, dropping to 1.05 from 1.13 in the prior-year period.
  • This marks the 12th consecutive quarter of declining fatalities, a sustained trend that began in mid-2022.

The National Highway Traffic Safety Administration (NHTSA) reported a continued and encouraging downturn in roadway deaths, with preliminary estimates showing an 8% decrease for the first six months of 2025 compared to the same stretch last year. This follows a 6.3% year-over-year decline the agency reported for the first quarter, a figure that has now accelerated.

The sustained drop represents the longest consecutive period of declining traffic fatalities in recent history and brings the semi-annual total to its lowest point in five years. The improvement comes even as vehicle miles traveled remained essentially flat, rising a negligible 0.6% according to the data. This indicates the decline is not merely a function of less driving but a genuine improvement in safety outcomes.

Agency officials, while expressing cautious optimism, were quick to emphasize that the absolute number of deaths remains unacceptably high. "While the trend is promising, we are far from declaring mission accomplished," a senior NHTSA official said, speaking on background. "Every life lost on our roadways is a tragedy, and we will continue our relentless efforts to promote safe behaviors, improve vehicle safety, and strengthen partnerships with law enforcement."

The positive trend was not uniform across the country, though it was widespread. Fatalities declined in 33 states, as well as in the District of Columbia and Puerto Rico. The reversal of the pandemic-era surge in risky driving behaviors—such as speeding and impaired driving—is widely seen as a key driver behind the improving numbers, alongside the gradual integration of more advanced safety technologies in the vehicle fleet.

Despite the progress, safety advocates argue regulatory bodies can and should do more. In recent congressional testimony regarding the reauthorization of the federal surface transportation program, the Insurance Institute for Highway Safety contended that NHTSA is "failing to meet the moment" on new vehicle safety regulations, suggesting the gains could be even greater with more aggressive policy action.

The full report with finalized data for the first half of the year is expected to be released by NHTSA in the coming months.
