Changing Lanes: Who Has the Right-of-Way?

When a driver in the left lane and a driver in the right lane both want to be in the middle lane, who has the right-of-way? 

Driving on Multiple-Lane Roadways 

Ahh, life on a road with three or more lanes. All the lane-choosing freedom you could ever want. Right lane, middle lane, left lane… the roadway is your oyster.

Of course, that’s not how it works as the roadway is never desolate. You share the multiple lanes with other drivers, and if there isn’t a known decor for how to share these lanes, that lane-choosing freedom quickly turns into lane-choosing madness.

Traffic Lane Basics

There are the commonly known traffic lane rules: left lane is for passing, right lane is for slower drivers, always use your turn signal when switching lanes, and don’t tailgate other drivers (please do not tailgate). Great! But what happens when Ashley in the left lane and Lori in the right lane both want to be in the middle lane? We spoke to an expert on Texas highways to learn more about how to handle this situation. 

The Texas Highwayman - Brian Purcell 

A traffic law superhero of sorts, Brian Purcell has been fascinated by transportation and traffic law since he was a middle school student in Germany. He even started a website about Germany’s transportation system while living there. Impressive, right? Since Germany, he’s moved to San Antonio where he maintains the Texas Highwayman website and attends Texas DOT public information meetings to give his input. Which is why we turned to him for today’s question:  “Who has the right-of-way when changing lanes?” 

 Who Has the Right-of-Way When Changing Lanes? 

texas traffic code law, chapter 545 Texas Traffic Code Law, Chapter 545

"According to the law, Lori would have to yield to Ashley. This is contrary to most right-of-way law in that traffic coming from the right usually has the right-of-way. The reason for giving preference to vehicles coming from the left in this circumstance is because traffic moving from left to right is trying to either yield the left lane for faster traffic or is moving to the right to prepare to exit or perhaps to move to the shoulder due to an emergency. In all of those cases, it’s obviously preferential to give those folks the right-of-way. This statute is also used to require traffic entering a freeway to yield to traffic already on the freeway."

 Conclusion 

We should note that even if you do have the right-of-way, it's always safest to yield the right-of-way to other traffic if possible. Not everyone is an Aceable driver; it's better to yield the right-of-way and avoid a traffic collision than to be legally correct and get hurt in a crash.

You should feel a little better about knowing how to safely change lanes on those big, multiple lane roadways.
