General information
Not specific to California

Where states publish an inspection price, it ranges from free (Illinois, Delaware DMV lanes, Ohio's first passing E-Check) to $55 every two years (Rhode Island). Many states let each station set its own price and only require it to be posted. Texas caps emissions tests at $11.50–$18.50.
