J., to my knowledge California is the only state that allows lane splitting. An April 13, 2005 article by www.motorway.com says

"California is the only state that permits lane splitting, but Texas is tinkering with the idea.

Washington has a bill that would make lane splitting legal, but it stalled in the Legislature and has almost no chance of passing.

The Texas bill would only allow lane splitting when traffic is going 20 mph or less and would require those who do it to be at least 21 years old and to have insurance.

In California, motorcyclists can split lanes as long as they do it safely. What that means depends on an officer's judgment."
