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).
Individual Tax Identification Number - is a nine-digit number issued by the Internal Revenue Service (IRS) to individuals who do not qualify for a Social Security Number (SSN). The ITIN always begins with the number 9 and has a 7 or 8 in the fourth digit. For example: 9XX-7X-XXXX.
