Practical advice still needs real evidence.

We start with the best sources.

When we say something factual about crash risk, driver behavior, licensing rules or safety outcomes, we go to primary sources first: NHTSA, the CDC, the Insurance Institute for Highway Safety, the Center for Injury Research and Prevention at Children’s Hospital of Philadelphia, peer-reviewed research, state motor vehicle agencies and state law. When the original research is available, we use it instead of someone’s summary of it.

We keep requirements and recommendations separate.

Your state’s supervised-hours minimum is a legal requirement. It isn’t a recommendation for how much practice your teen needs to become a capable driver. So we label the difference every time.

We write for the car, not the bookshelf.

Ten years of building DRVN with families has taught us that parents rarely need another list of statistics. They need to know what to do differently because of them. If research says newly licensed drivers face a spike in risk, the useful question is what you should do in those first months.

Evidence matters most when it changes what happens on a Tuesday night drive.

We don’t oversell.

Teen driving is serious, and good writing shouldn’t make thin evidence sound strong. A correlation isn’t a cause. One promising study isn’t universal proof. An early survey of DRVN families isn’t a controlled trial.

Our surveys have shown encouraging signs, including lower crash and violation rates. We treat those as signals, not as proof that DRVN causes a particular outcome. We’d rather be precise than impressive.

Experience counts, but it doesn’t replace evidence.

Research describes patterns across thousands of drivers. It can’t tell you what’s happening in your passenger seat today. DRVN also draws on a decade of work with parents, teens, instructors and the traffic-safety community, including testimony at the Ohio Statehouse.

That experience shapes how we read the evidence. It doesn’t stand in for it. We think you need both.

We keep things current.

Licensing rules vary by state and they change. Our state guides link to the official government source and show when we last checked them. Our major guides get reviewed against current research, too.

A publish date tells you when something was written. A last-reviewed date tells you when we last made sure it was still right.

We show our work.

Important claims link to their sources wherever we can manage it. We’re not asking you to trust DRVN instead of NHTSA, the CDC, IIHS, CHOP or your state. We’re trying to tell you what they add up to, and give you a practical way to act on it. The research behind our guidance is collected, with its limits, in the DRVN evidence library.

We say what we think.

DRVN works alongside government, insurers, driving schools, researchers and technology companies. We respect what each of them does. We’ll also say so when the system leaves parents holding a problem nobody has solved.

Your state sets a minimum. Driver’s ed provides essential instruction. Neither one removes the need for a lot of practice with you. That gap is why DRVN exists.
