I just looked it up and "lane splitting" is not allowed in the state of New York- http://www.americanmotorcyclist.com/Rights/State-Laws.aspx?stateid=32Helmholtz Watson said:I'm pretty sure your friend is in the wrong and what they were doing is illegal.Xiado said:As someone who lives in NYC, it's a really biker-unfriendly place. A lot of drivers are massive assholes and will antagonize bikers. I personally know someone who was riding his motorbike up the middle of two stopped lanes in a traffic jam, and a spiteful person opened his car door to stop my friend, potentially causing an accident if he was going any faster.
Now to check out what my state allows...
Edit: turns out it's not legal in any state, only kind of allowed in California.
