(g) The Motor Vehicle Sales and Use Tax imposed by the Texas Tax Code, Chapter 152, does not apply to motor vehicles, trailers, and semitrailers taxed under Chapter 157; and the taxes imposed by Chapter 157 do not apply to motor vehicles taxed under Chapter 152; provided that, if a motor vehicle, trailer, or semitrailer taxed under Chapter 157 ceases to be used as an interstate motor vehicle, trailer, or semitrailer within one year of either the date the vehicle was purchased in Texas or the date such vehicle was first brought into Texas, the taxes imposed by Chapter 152 will apply at that time.
