There are nearly 240 million licensed drivers in the U.S., which means more than 9 in 10 driving–age adults hold a license. Yet the federal government does not govern how states test, train, or license drivers, with regulations remaining state-driven across the country.
This study will look closely at state differentials to consider disparities in driving standards and find the states with the least rigorous driving license demands. We’ll also consider the consequences of varying standards, including the measurable effect on insurance premiums. Ultimately, low or lax road standards in specific states mean more precarious roads for drivers negotiating the roads in question.
Before we get into licensing and driving standard disparities, let’s take a broad look at U.S. driving license holders by age group.
U.S. Driver’s Licenses: The Facts
Driving is an American norm, with the vast majority of driving-age adults holding a license. But what does the U.S. license holder’s spread look like across various age groups?
Licensed Drivers by Age Group
Millions of drivers are part of the infrastructure of daily American life. And with a lack of adequate public transport options in many parts of the country, cars are often a must-have.
Driving license figures across all U.S. age groups tell their own story.
Teens aged 19 and younger have the lowest licensee rate (34.2%). That said, this still translates to more than 9 million teenagers behind the wheel. And drivers in this bracket represent one of the highest-risk age groups.
Rates climb sharply through young adulthood, with 80.9% of drivers in the 20–24 bracket licensed. That’s nearly 17.9 million license holders, many of whom navigate roads with limited real-world experience.
89.3% of the 25–29 age group is licensed (nearly 19.8 million people), with rates continuing to steadily climb through consecutive age groups: 30–39 (90.7%, 42.4 million drivers), 40–49 (91.5%, 38.9 million), 50–59 (92.1%, 37.6 million), 60–69 (92.3%, 37.6 million).
Among drivers aged 70–79, the rate dips slightly to 91.1%, a number that still represents over 25.4 million active license holders. Drivers in this age group usually possess enormous levels of experience, but often suffer failing competency, which can be a problem in states that don’t prioritize re-testing.
A sharp licensee decline occurs among 80–84 year–olds. For this age group, the number falls to 87.5%: just over 6.3 million licensed drivers. And for those aged 85+, the licensee rate plummets to 71.2% (4.5 million). For both groups, re-testing requirements are inconsistent and, in some states, nonexistent.
Beyond raw licensee numbers, the integrity of the licensing system at every stage of life is crucial. When standards are inconsistent, under-tested, or unenforced, the consequences are real. A state with a lax licensing system potentially endangers all its drivers.
And with varying levels of re-testing protocol or penalties for ailing competency across all states, the proportion of a state’s licensees who are over 75 can offer some indication of a potential problem.
States With Disproportionate Senior Driver Numbers
The following states have the highest proportion of senior drivers. That’s not to say that individual drivers of any age are necessarily problematic, but it does indicate a probable need in each state’s case for stringent re-testing programs and mindfulness regarding the potentially waning competency of high numbers of drivers on the road.
Arkansas leads the country when it comes to its proportion of senior drivers: 14.29% of its licensed drivers are aged 75 or older. That’s nearly 1 in 7, or 424,259 drivers.
Here are the other states that feature the highest proportion of senior drivers: many of them are rural states, where driving is often a lifeline, and demands for re-testing and driver competency checks are often low.
Florida, although ranking ninth on the per capita list, features by far the highest raw total of all ranked states (1,842,157), a reminder that proportion and scale are very different matters.
Across eight of the ten states in question, drivers aged 75+ are able to renew their license without being retested. In fact, just two states make it obligatory for 75+ drivers to re-test when renewing their license: Illinois and New Hampshire.
And even those rare examples are subject to amendment: Illinois will raise its road test age from 75 to 87 from July 2026, effectively removing one of the few remaining safeguards in the system.
Let’s widen our focus to look at the states that feature the most licensed drivers.
Top 10 U.S. States: Most Licensed Drivers
When adjusted for driving-age population, North Carolina leads the nation with approximately 92,626 licensed drivers per 100,000 residents aged 18 and over, followed closely by Ohio (90,322) and Pennsylvania (86,737), states where car dependency is deeply embedded in the fabric of daily life and public transit alternatives are limited outside of major urban centers.
Georgia (90,070) and Michigan (89,781) also rank among the highest per capita, reflecting both the cultural centrality of car ownership in the South and the historical legacy of automotive manufacturing and infrastructure investment in the Great Lakes region.
That Georgia and North Carolina rank so prominently on a per capita basis is consistent with broader trends of rapid population growth and suburban expansion reshaping the Southeast, where sprawling development patterns make driving not just a preference but a practical necessity for most residents.
Florida (86,554) and Illinois (87,124) sit in the middle of the per capita rankings. At the same time, Texas (85,718) ranks toward the lower end of the adjusted list, reflecting its substantial and fast-growing population of younger and non-driving-age residents.
California, despite having the most licensed drivers of any state in the nation at 27.8 million, ranks last among the top 10 on a per capita basis at 89,151 per 100,000, a function of its enormous overall population rather than any lower propensity to drive.
New York rounds out the per capita rankings at the bottom of the top 10, a result consistent with its comparatively robust public transit infrastructure, yet even here, the sheer volume of 12.4 million licensed drivers underscores how deeply ingrained car ownership remains even in one of the few U.S. metros where driving is genuinely optional.
Together, these 10 states account for more than 126.6 million licensed drivers, more than half of all licensed drivers in the United States.
Clearly, much of the country’s road safety burden rests with a relatively small number of jurisdictions, meaning that their licensing eligibility standards carry significant consequences for all drivers sharing those roads. And when those standards are inconsistent, unenforced, or lack adequate rigor, the effects have national repercussions.
Varying Driving License Standards
Among the 10 states with the most licensed drivers, the rules governing how drivers earn the right to drive often fall well short of safety expert recommendations.
The Insurance Institute for Highway Safety suggests 70 hours of supervised practice, a minimum permit age of 16, and a nighttime restriction on graduate drivers to be imposed no later than 8 p.m. as current best-practice benchmarks.
Not one top 10 state meets all those standards. Pennsylvania comes closest: the state demands 65 supervised hours, including 10 at night and 5 in adverse weather. New York mandates 65 hours of supervision (15 at night) plus a unique geographic restriction, while its junior license holders can only drive while supervised.
Yet those states are outliers. Georgia and North Carolina, both among the nation’s fastest-growing driver populations, demand a meager 6 supervised nighttime hours and issue permits to 15–year–olds, as do Texas and Florida.
The safety gap matters: the fatal crash rate per driven mile for 16–17–year–olds is around 3 times the rate for drivers aged 20 and older. The study data is unequivocal: inexperience, not recklessness, is at the root of that differential.
Michigan compounds the inexperience issue by offering learner permits to drivers as young as 14 years and 9 months, the youngest eligibility threshold in the top 10.
Texas, meanwhile, stands alone by extending its driver education requirement to adults between 18 and 24, a clear recognition that training shouldn’t necessarily stop at the teenage years. Young adults without any formal driving education face crash involvement rates over 60% higher than those who completed training.
Taken together, these 10 states account for nearly half of all licensed drivers in the country, and disparities regarding their standards are more than minor procedural differences. They’re the difference between a licensing system designed to produce safe drivers and one designed to simply issue licenses, with crash data reflecting the distinction.
And what of the actual driving license tests in these states? As the data reveals, there’s still a disparity, with some tests far easier than others.
Variable State Driving Test Standards
A state-by-state analysis of driving test standards across the ten most-licensed states in the country reveals a wide and troubling gap in how rigorously states screen drivers before putting them on the road.
To rank the states, we scored each test using a methodology that harnessed publicly available DMV data across seven factors. These included minimum pass threshold, number of test questions, and retake waiting periods.
The difficulty scores across these states range from just 2/100 to 78/100, exposing a system where the demands necessary to earn a legal right to drive varies dramatically from one state to another.
Let’s focus on the states that feature the least taxing driving tests under review.
Ohio’s Comparatively Lax Standards
Ohio, one of four states ranked ‘lenient’ regarding their driving tests, presents perhaps the starkest example of lax driving test standards.
Home to over 7.8 million licensed drivers, Ohio scored just 2/100, a near-zero rating that reflects a particularly undemanding written knowledge exam. The exam involves a 40-question multiple-choice knowledge test (with a 75% passing threshold). There are no demands for prior training for adults over 18, there’s no practical component, and no minimum preparatory classroom hours are required before the exam.
Ohio holds its beauty professionals to significantly higher standards: aspiring cosmetologists must complete 1,500 hours of board-approved training before they’re even eligible to sit for their licensing exam; barbers must log 1,800 hours of education; nail technicians must complete a state board-approved program before sitting for both a written and practical examination.
So, someone legally permitted to cut hair, apply acrylics, or give a shave in Ohio has undergone much more supervised training than someone permitted to operate a vehicle at highway speeds on a public road.
New York isn’t far behind Ohio with a 4/100 rating (despite being home to over 12.4 million licensed drivers). Notably, New York also produces some of the lowest national teen driver fatality rates, a reminder that written test difficulty does not determine road safety outcomes, nor suggest that stronger graduate driver licensing provisions can compensate for what a knowledge exam lacks.
Texas, with a pass threshold of just 70% (the lowest of any state in the rankings), earned a test difficulty score of 30/100 while suffering 620 teen traffic fatalities in 2023, the highest of any state analyzed.
Illinois, despite requiring an 80% pass threshold, scored only 16/100 due to the relative simplicity of its exam.
Among all the states under review, only Pennsylvania is ranked ‘rigorous’, scoring 78/100 with the highest pass threshold in the group (83%) and 65 required supervised driving hours, the state closest to meeting IIHS safety benchmarks.
In the states where the majority of American drivers are licensed, the written knowledge test is less a meaningful safety filter and more a low-stakes formality, often doing very little by way of ensuring that drivers are fully equipped for the road.
Formal driving education is often a very important factor when it comes to driver preparation, but not all drivers are equally equipped.
Formal Driver Education Gaps
The consequences of skipping formal driver education don’t show up on a report card: they show up on a crash report.
Young adults between the ages of 18 and 24 who never completed formal driver training suffer a disproportionately high crash rate.
According to the Washington Traffic Safety Commission’s 2023 report, for those aged 18 to 20 with incomplete training, their crash rate is 67% higher than that of those who completed their training; for those aged 21 to 24, the figure is 60%.
The gap is a direct reflection of the extent to which a new driver was taught to recognize a hazard before it became an emergency, how to handle a vehicle in low-visibility conditions, or what to do in an unprecedented high-speed scenario. These are skills that are taught, not naturally accrued.
Yet across the country, driver’s education remains optional in many states, incomplete in others. For a licensing system already struggling to enforce meaningful standards, an undertrained generation of new drivers is further cause for concern.
The Insurance Premium Factor
The insurance industry observes a simple formula: more risk on the road means higher premiums for all drivers.
Nevada ($335/month), Louisiana ($327/month), and Florida ($311/month) are among the three most expensive states in the country for full coverage car insurance (the national average is $208/month). Not coincidentally, all three are ranked as lenient regarding their demands of new drivers.
New York, another lenient-ranked state, averages $226/month for full coverage, while Texas (also rated as lenient) has been subject to the largest car insurance increase of any state over the past five years: its rates have climbed 60.9% and currently average around $212/month.
Georgia averages $275/month, while North Carolina, despite a moderate rating, averages just $153/month, likely driven by a highly-rated highway infrastructure.
Ultimately, driver safety levels, which are influenced by driver licensing standards, clearly and directly affect car insurance premiums.
Improving Licensing Standards Equals Safer Roads
Across the United States, nearly 240 million licensed drivers share roads governed by 50 often very different sets of rules. And driving license standards remain entirely state-driven, with no federal imperative regarding how rigorously a state must test, train, or screen its drivers.
The result is a patchwork system that means a driver’s competency largely depends on where they live. Among the ten most-licensed states (home to around half the country’s drivers) written knowledge test difficulty scores range from just 2 out of 100 in Ohio to 78 out of 100 in Pennsylvania, exposing a licensing landscape that often varies dramatically across state lines.
Across eight of the ten states in question, drivers aged 75+ are able to renew their license without being re–tested
Graduated driver licensing standards tell a similarly uneven story: not one of the top ten states meets all of the Insurance Institute for Highway Safety’s best-practice benchmarks.
States like Georgia and North Carolina (among the fastest-growing driver populations in the country) require as few as six supervised nighttime hours before a teenager can drive independently. Michigan issues learner’s permits to drivers as young as 14 years and 9 months old, while Texas, with a pass threshold of just 70%, recorded 620 teen traffic fatalities in 2023, the highest of any of the states under consideration.
For young adults who never completed formal driver education, the consequences are measurable: their involvement in crashes is over 60% higher than for those who completed training, yet driver’s education remains optional across much of the country.
And older drivers represent a growing share of the licensed population in states like Arkansas, where nearly 1 in 7 licensed drivers is 75 or older. Yet only two states in the country mandate a road test for renewing older drivers, with even that limited standard soon to be diminished, as Illinois prepares to raise its road test age from 75 to 87 in July 2026.
Additionally, the insurance rates in states with lenient driving license demands are significantly higher than in those with more stringent standards.
Overall, the data makes it clear: the United States has facilitated an inconsistent driving culture in which a driving license is often fairly easy to obtain.
The country’s roads would clearly benefit from a more consistent, universal driving standard that enforces young drivers to undergo a suitable level of education and training, and makes sure older drivers with waning driving abilities are more stringently tested. If this were to be put in place, lower crash and fatality numbers, as well as lower insurance bills, would vindicate its introduction.
