The new law authorizing a crackdown on repeat drunk drivers is among a slate of new laws that went into effect Saturday.

More than 150 of the laws that the Legislature passed earlier this year went into effect on Oct. 1. Most are considered relatively small adjustments to current law.

But one of the larger new laws is the so-called "24/7" program that was overwhelming endorsed by lawmakers with the strong backing of Attorney General Steve Bullock.

The program requires repeat DUI offenders to take a breath test twice a day, every day, at their own expense from the time of arrest until their sentence is completed.

A half dozen counties will have their programs up and running soon, while others are expected to later start voluntary participation in the program.
