Because some things change when you cross the line...

Compiled after over 11+ years of full time RV road-tripping across the USA, State Lines is an indispensable traveler’s guide to highly variable state laws and regulations.

Currently State Lines tracks over 55 pieces of travel relevant information for each of the 50 states; including cell phone & texting bans, seat belt & child safety seats, state sales tax exemptions, gas/diesel taxes, bottle deposits, time zones, towing & RV specific laws, rest area overnight parking limits, state park camping entrance fees, default speed limits, radar detectors, highway emergency #s, alcohol sales laws & taxes, smoking bans, open container laws, pet leash laws, bicycle helmet laws, motorcycle laws (helmet, lights, eye protection & lane sharing), left turns on red, u-turns, keep right and more.

State Lines is location aware, so it can automatically show you information about nearby states. The entire State Lines database is integrated into the application, so State Lines works when you are out of cellular or Wi-Fi coverage.

When you visit a new state, have you ever wondered:

What restraints for my kids are required in this state?
Is the sales tax lower over the next state line?
Is the fuel tax cheaper here?
Can I buy beer in the grocery stores?
Can I overnight in rest areas?
Is smoking allowed in restaurants?
Are radar detectors legal?
Can I make a left turn on red?
Are helmets & eye protection required?

State Lines is an essential application for anyone traveling around the United States - whether by RV, car, train, bike, plane, or boat. No matter how you travel, if you’re frequently crossing state lines, you need State Lines.

State Lines is a growing project - by travelers for travelers - and we welcome feedback on ideas for other useful state specific information to include in future versions. Please let us know what else you would like us to track!

****** NOTES *******

State Lines is intended to provide an at-a-glance summarized guide to rules and regulations, and it is not an exhaustive legal reference. While every effort has been made to provide quality up to date data, no warranty for accuracy of data is expressed or implied. State Lines assumes no responsibility for how you utilize the data. Keep in mind, local regulations can often override state level rules (so while a state may not have a cell phone ban, a city may - which will not be reflected in State Lines), and laws frequently change. Always verify with the proper authorities before assuming anything.

Gun Laws: Please note, State Lines has not included this feature in a long time. We recommend apps like 'Legal Heat' - which is updated regularly by the experts on this very complex topic.

We will be keeping State Lines up to date with periodic updates. This is a time consuming manual research process, and we appreciate your patience and understanding if things get out of date. You can help though - if you do discover any out-of-date information in State Lines, please contact us at statelines@technomadia.com. Thanks!

What's New

Version 2017.4

Fully updated: April 2017

This long overdue update brings 'State Lines' up to date with all the latest information on tax rates, cell phone rules, seat belts & child safety seat laws, drinking regulations, smoking bans, default speed limits, and more!

We've also updated the app to support newer versions of iOS, and changed the displayed Gas and Diesel tax to display State Tax only, instead of combined State and Federal Taxes.

If you appreciate these continued free updates to State Lines, we'd love it if you left a review on the App Store!

These updates are funded entirely by new app sales... and positive reviews help folks decide if this app is right for them. Thank you!

NOTE: We are still planning to fully rewrite State Lines to be a more "modern" app, and this will hopefully come later this year. This current quick update was focused on pushing out a fully updated database, and making sure that the app would remain compatible with future iOS versions.

Ratings and Reviews

Very useful app


This is a very good and useful app for travelers, RV'ers, etc., providing lots of useful, helpful information concerning all 50 states, especially regarding speed limits, towing info, rest area parking, etc., etc.. The info for every state is organized consistently from state to state. I highly recommend it.

Must Have for Traveling!


I used this on a recent road trip of over 2500 miles and it was an extremely helpful reference when planning gas stops (because of the tax rates). I also liked being able to check speed limits and local laws like turning on red, hands free phoning, texting, etc. Before this app, I used to just wonder about these things and never got around to doing the research myself, always hoping I was within the law. But if you get pulled over, they will tell you that ignorance is no excuse. This app can prevent that.

Great for the traveling family

RV Dread Head

I do not travel as often as I would like, so when I do I need all the help I can get. This app is wonderful for knowing if you really are going to need that booster seat for your preschooler once you get halway to your destination. Or whether you can you call grandma back hands-free.

My husband knows whether it is worth it or not to save some purchases for when we enter a new state with a lower sales tax. And Mommy can plan her alcohol purchases around individual state restrictions.

It is ideal for a family road trip.
