Across the States: Understanding National Driving Standards

Ah, the classic American road trip. There’s nothing quite like hitting the open road, exploring new places, and experiencing the diverse landscapes the U.S. has to offer. But as you cross state lines, you might notice some driving rules change.

Here’s what you need to know to stay safe and compliant on your next journey. 

Driving Laws in the U.S. 

In the United States, traffic laws are primarily governed at the state level. This means that while there are overarching national standards, each state has the authority to establish its own specific regulations. Basic rules, like the meanings of traffic light colors, are universal. However, laws governing speed limits, seat belt requirements, and cell phone usage can vary widely. 

Is Your License Valid Across State Lines?

Yes! A valid license from one state allows you to drive in any other state. However, it is important to note that while you can legally drive with an out-of-state license, you are still subject to the traffic laws of the state you are in. Long-term residents or those moving to a new state will eventually need to transfer their license to their new state of residence, typically within 30 to 60 days. 

Common Laws That Differ from State to State

Several driving laws differ significantly between states, impacting everyday driving behaviors. Here are some key examples.

  • Speed limits: While most highways have speed limits between 55 and 75 mph, some states, like Texas, have sections of roadways with limits up to 85 mph.
  • Seat belt laws: All states except New Hampshire require adults to wear seat belts. But the specifics, like whether violations are primary or secondary offenses, can vary.
  • Cell phone use: Handheld cell phone use while driving is banned in some states, like California and Arizona, while others don’t have statewide prohibition (though there may be local ordinances). 
  • Right turn on red: While generally allowed, some states, like New York, have restrictions that prohibit it unless posted otherwise. 

Standard Laws Across All (or Most) States

The specifics might change from state to state, but there are a handful of traffic laws that apply throughout the country, such as:

  • DUI laws: While the consequences of driving under the influence can vary, a blood alcohol content (BAC) of 0.08% is the legal threshold in all states.
  • Traffic signals: The meaning of many traffic signs and signals, such as stop signs and traffic lights, are consistent across all states. 
  • Keep right laws: Wherever you are, if you’re traveling under the normal speed of traffic, you must keep the furthest right lane. 
  • Move over laws: In all 50 states, drivers must change lanes to leave a “safe zone” for stopped emergency vehicles.

Preparing to Drive Out of State

Preparation is key to driving safely in a new state. Here are some steps to help you stay compliant.

  • Research before you go: Look up specific traffic laws for the state you’ll be visiting. Websites like the DMV for each state can provide detailed information. 
  • Use navigation tools: GPS and smartphone apps often have updated traffic law information and can alert you to local regulations. 
  • Observe road signs: Pay close attention to road signs, which often provide critical information about speed limits, lane usage, and other local laws.
