When it comes to keeping drivers safe, you might assume that tougher traffic laws, higher speeding fines, and increased enforcement automatically lead to fewer deadly crashes. But a new 2026 study suggests the relationship between traffic laws and road safety may be much more complicated.
Research from Davidoff Law Personal Injury Lawyers compared traffic laws, enforcement, and crash statistics across all 50 states. The study looked at factors including average speed limits, speeding fines, the number of traffic safety laws, DUI arrests, and changes in fatal crashes.
One of the biggest takeaways? Some states with particularly strict traffic laws have still experienced increases in fatal crashes.
Illinois Tops the List for Strict Traffic Laws
According to the study, Illinois received the highest law strictness score in the country at 90 out of 100.
The state has 10 of the 11 traffic safety laws examined in the study, an average speed limit of 63 mph, and an average speeding fine of $330.
Illinois has also seen increased DUI enforcement. DUI arrests reportedly increased 28.6% between 2020 and 2025 and represented about 10.4% of total arrests.
Despite those measures, the study found fatal crashes increased 18.7% between 2015 and 2024.
That doesn’t necessarily mean tougher traffic laws aren’t working. Crash rates can be influenced by everything from driver behavior and road conditions to population changes, vehicle miles traveled, infrastructure, weather, and enforcement practices. What the findings do suggest is that traffic laws are only one piece of a much larger road-safety puzzle.
California Has Some of the Highest Speeding Fines
California came in second in the study’s ranking of states with the strictest traffic laws.
Drivers caught speeding can face an average fine of $342, the highest figure among the states highlighted in the report. California also has 10 of the 11 traffic safety laws considered by researchers.
Even with those laws and fines, the study found fatal crashes increased 14.7% over the decade examined.
Washington Saw a Significant Increase in Fatal Crashes
Washington ranked third and has all 11 of the major traffic safety laws included in the study.
The state also stood out for DUI arrests, which represented approximately 16.4% of total arrests. Its average speeding fine was $276.
However, Washington experienced one of the largest increases in fatal crashes among the states at the top of the study. Fatal crashes increased by roughly 35% between 2015 and 2024.
When researchers compared the most recent five-year period with 2015–2019, fatal crashes were also substantially higher.
Rhode Island Combines Lower Speed Limits With Higher Fines
Rhode Island ranked fourth.
The state has an average speed limit of approximately 58 mph and an average speeding fine of $312. Researchers also found DUI arrests increased by about 10.8% during the period examined.
Fatal crashes, meanwhile, increased approximately 17% over the decade.
Again, these numbers shouldn’t be interpreted as proof that enforcement or stricter laws caused the increase. Instead, they illustrate how difficult it can be to connect one particular policy with overall road safety.
Hawaii Shows a Different Recent Trend
Hawaii rounded out the top five and offered an interesting contrast.
While fatal crashes increased approximately 14.1% across the full decade analyzed, researchers found that the most recent five-year period showed improvement. Fatal crashes were down approximately 6.2% when compared with 2015–2019.
Hawaii has eight of the 11 traffic safety laws examined, an average speed limit of 58 mph, and an average speeding fine of $276.
DUI arrests also declined by more than 20% from 2020 through 2025.
Other States With Strict Traffic Laws
The study’s top 10 also included Oregon, New York, Arizona, Maryland, and Louisiana.
New York stood out because DUI arrests declined approximately 27% between 2020 and 2025. Fatal crashes across the full decade were also slightly lower, although the comparison between the two five-year periods showed an increase.
Arizona, meanwhile, experienced one of the largest increases in fatal crashes among the states listed, with researchers reporting an increase of nearly 38% over the decade.
Why Tougher Traffic Laws Aren’t the Whole Story
One of the most important things to remember about this research is that correlation doesn’t necessarily mean causation.
A state can have strict traffic laws and still experience rising crash numbers. Likewise, a decrease in arrests doesn’t automatically mean police are enforcing laws less aggressively.
Ruben Davidoff, Managing Partner at Davidoff Law Personal Injury Lawyers, noted that arrest and fatality statistics can have multiple explanations. Fewer DUI arrests, for example, could reflect changes in enforcement or could mean fewer people are driving while impaired.
Road infrastructure, economic conditions, enforcement priorities, driving habits, population growth, and other factors can also influence crash statistics.
The study’s findings therefore shouldn’t be read as evidence that traffic laws don’t matter. Instead, they highlight that fines and laws alone may not be enough to address road safety.
What This Means for Your Wallet
Traffic laws aren’t only about safety. Breaking them can get expensive quickly.
A speeding ticket can cost hundreds of dollars before you even consider possible court costs or increases in auto insurance premiums. More serious violations can bring significantly larger financial consequences.
That’s why one of the simplest money-saving habits behind the wheel is also one of the most obvious: slow down, stay focused, buckle up, and avoid driving impaired.
You don’t need a $300 speeding ticket eating into your monthly budget to remind you that getting somewhere a few minutes faster usually isn’t worth the financial—or personal—risk.
The Bottom Line
The study provides an interesting look at how traffic laws and crash statistics differ across the country, but road safety can’t be reduced to one fine, law, or enforcement strategy.
Illinois may have received the highest law-strictness score in this particular analysis, while California has some of the largest speeding fines. Yet several states with strict laws have also experienced increases in fatal crashes.
The bigger lesson is that safer roads depend on a combination of sensible laws, effective enforcement, safer infrastructure, responsible driving, and individual choices behind the wheel.
And whether you’re driving in Illinois, California, North Carolina, or anywhere else, following the rules of the road can protect more than your wallet—it can help protect everyone sharing the road with you.
