State Lines

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

Compiled after over 20+ 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 45 pieces of travel relevant information for each of the 50 states plus DC; including electronic device use, seat belt & child safety seats, state sales tax exemptions, gas/diesel taxes, bottle deposits, plastic shopping bag bans, time zones, towing & RV specific laws, rest area overnight parking limits, state park camping fees, default speed limits, radar detectors, highway emergency #s, alcohol sales laws & taxes, smoking bans, open container laws, pet leash laws, e-bike laws, bicycle helmet laws, motorcycle helmet laws, 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 internet access.

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

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 required?
What restraints for my kids are required in this state?


KEY FEATURES:
+ Quick Compare: You can pick up to three favorite data fields to be displayed on the main screen, making it easy to compare nearby states.

+ Custom Sorting: You can sort the state list alphabetically, by distance from you, and by your selected Quick Compare fields. If you’ve ever wanted to see what state has the lowest alcohol or fuel taxes, this feature makes it easy!

+ Custom Page Ordering: State Lines has six pages of detailed information per state. You can rearrange these pages so that your favorite pages are first.


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.

****** 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 plastic bag bans, 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 attempt to keep State Lines up to date annually This is a time consuming manual research process, and we appreciate your patience and understanding that things WILL get out of date.

State Lines is a personal passion project that has been maintained in the App Store for over 15 years, and takes a tremendous amount of time to manually research and update. This app was first released in 2010, pre-dating the era of in-app subscriptions - so the app only generates income from new app sales.

If you want

This is the most significant update of State Lines in a decade - every data field has been updated, double-checked, and verified to be current as of early 2026. Fields that are no longer relevant or difficult to update have been removed - such as many default state speed limits and automated traffic enforcement laws.
