Smog or emission check facilities are common in states with tight air pollution controls.

Emissions testing shops must hold special state licenses and in some cases, licensing agreements to operate their computer systems.
Once the capitol of the Republic of the Rio Grande, Laredo remains an important center of cross-border trade. The once small town is now a booming center of international commerce with strong trade, transportation, and utilities sectors. Like most Texas cities, Laredo keeps licensing requirements minimal and invites entrepreneurs to set-up shop. The majority of business regulation instead takes place at the state level.
