April 15, 2025 – The AAA Foundation for Traffic Safety has released a sweeping 196-page report that paints a troubling picture of American driving habits: 79% of U.S. drivers admit to speeding at least occasionally, and the practice has become so routine that many no longer consider it a violation.
The study, based on a nationally representative survey conducted in late 2024, reveals that the threshold for what drivers classify as “actual speeding” has shifted significantly. On residential roads, arterials, and rural highways, most respondents said they do not consider a driver to be speeding until they exceed the posted limit by an average of 10 mph. On urban highways with a 70 mph limit, the perceived speeding threshold rose to 78 mph — a full 8 mph over the legal limit.
This collective leniency has real-world consequences. According to the National Highway Traffic Safety Administration's preliminary data, speeding was a contributing factor in nearly 30% of all traffic fatalities in 2024 — a figure that mirrors the AAA report's findings. The study notes that 30% of drivers surveyed agreed with the statement “no one actually drives the speed limit,” suggesting a widespread normalization of law-breaking behind the wheel.
Among the 79% of respondents who identified as speeders, about one-third described themselves as “rare” speeders, while another 30% said they speed “sometimes.” Fifteen percent admitted to being frequent speeders. Only 21% of drivers claimed they never exceed the speed limit.
The top motivations for speeding are predictable: 31% said they do it to pass slower drivers, 25% to reach their destination faster, 21% to avoid holding up traffic, and 19% said it’s simply part of their normal driving behavior.
Conversely, the primary reasons for not speeding were fear of receiving a ticket (79%) and concern about crash involvement (72%). Notably, 60% of drivers cited bad weather as a reason to slow down, indicating that environmental conditions still influence speed choices.
The study also explored what measures drivers would accept to curb speeding. Overwhelmingly, 87% of respondents supported increased police presence in areas with a history of speed-related crashes. Automated speed cameras received 71% support — a surprising figure given the vocal opposition such systems often face in the U.S. over privacy and government overreach concerns.
However, support dropped sharply when it came to traffic-calming infrastructure. Only 43% favored speed humps in crash-prone areas, 40% supported rumble strips, and roundabouts earned just 39% approval. This suggests that while drivers are willing to accept enforcement that doesn’t directly impede their daily commute, they resist physical changes that alter road design or force slower speeds.
The AAA report also gauged attitudes toward in-vehicle technology. Intelligent speed assistance (ISA) — which can warn drivers or automatically reduce speed to match the posted limit — is gradually being introduced in new vehicles. Drivers were relatively comfortable with a dashboard warning that alerts them when they are speeding (support dropped only slightly from the baseline). But support for systems that would automatically slow the vehicle down to the speed limit fell sharply. Unsurprisingly, drivers were more accepting of a defeatable speed limiter (one they can turn off) than a hard limit that cannot be overridden.
This mirrors a broader global debate: the European Union will mandate ISA in all new cars from July 2024, but the U.S. has no such requirement. The AAA study suggests that voluntary adoption of ISA with warnings might be more palatable to American drivers than mandatory speed-limiting systems.
“The data make clear that speeding is not seen as a serious transgression by most drivers,” said Dr. Mark Stevens, a senior researcher at the AAA Foundation. “We need a multi-pronged approach that combines enforcement, education, road design, and technology to change this norm.”
The report arrives as the National Transportation Safety Board continues to push for universal speed limiters in all new vehicles. Meanwhile, several states — including New York, California, and Washington — are piloting automated speed enforcement programs. The AAA study could provide ammunition for both sides of the debate.
The AAA report’s core finding — that speeding is now “widely perceived as socially normative behavior among drivers” — underscores the challenge facing safety advocates. With nearly one in three traffic fatalities linked to speeding, and the majority of drivers not considering 10 mph over the limit to be a problem, changing attitudes will require sustained effort.
As the study notes, “the normalization of speeding presents a significant barrier to achieving Vision Zero goals.” Until drivers accept that even a few miles per hour over the limit can be deadly, the U.S. may continue to see thousands of preventable deaths each year.
