"County supervisors approved a pilot program to place alcohol-detecting ankle bracelets on chronic drunken drivers.
Repeat offenders in the program will be required to wear the anklets for 90 days while on probation. The program will then compare their recidivism rate with offenders who did not wear bracelets."
