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).
Like an SSN, an ITIN number is nine-digits in the format xxx-xx-xxx. But the first digit will always be a 9, and the second section of the number will be in the range of 70-88 (e.g., 9xx-88-xxxx). Since the program began in 1996 the IRS has issued 21 million ITINs. To obtain an ITIN an alien with foreign status should complete Form W-7, Application for IRS Individual Taxpayer Identification Number. By law, an alien individual cannot have both an ITIN and a SSN.
