District Attorney Susan Doyle sought and received a grant from the Governor's Highway Safety Program to pay for the court, which will operate three days a week through Sept. 30, 2009. The grant is for $167,309.

Doyle says she hopes it will improve the county's relatively low conviction rate for driving while impaired charges.

In 2006, county prosecutors voluntarily dismissed about 43 percent of impaired-driving charges, according to court records. That compares to a 14 percent dismissal rate statewide that year.
