I'm not sure what lane splitting is. I am going to assume you mean driving in two lanes, and No it is not legal. I live in TX. It is called lane sharing, and it is legal in California when there is more than one lane in each direction.
An ITIN, or Individual Taxpayer Identification Number, is a tax processing number only available for certain nonresident and resident aliens, their spouses, and dependents who cannot get a Social Security Number (SSN). It is a 9-digit number, beginning with the number 9, formatted like an SSN (NNN-NN-NNNN).
A unique seven-, eight- or nine-digit number assigned to a noncitizen at the time his or her A-file is created. The 9-digit U.S. Citizenship and Immigration Services number listed on the front of Permanent Resident Cards (Form I-551) issued after May 10, 2010, is the same as the Alien Registration Number. The A-number can also be found on the back of these Permanent Resident Cards.
