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).
Generally, an EIN number is used to file various IRS business tax returns, open business bank accounts, obtain business licences, etc. The federal tax identification number is nine (9) digits long and is issued in the following format: XX-XXXXXXX. Essentially, it is similar to a Social Security Number (SSN) for an individual, but an EIN number is for businesses and entities.
