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).
It is a nine-digit number that begins with the number 9 and generally has a range of 70 to 99 (excluding 89 and 93 and 18) in the fourth and fifth digit, example 9XX-70-XXXX or 9XX-99-XXXX. The excluded range in the fourth and fifth digits are only issued as temporary taxpayer identification numbers.
