Newly doubled fines and further efforts to embarrass drunken drivers are fueling a debate on how best to curb Arizona's mounting death toll from alcohol-related collisions.

Some state lawmakers and groups such as Mothers Against Drunk Driving say they need a multifaceted strategy to discourage impaired drivers from getting behind the wheels of their cars.

But officials who have dealt with drunken drivers in the state's criminal justice system say the answer is more police, education and treatment.

Alcohol-related collisions cost nearly 800 people their lives in Arizona during the three-year period from 2000 through 2002.

"There's not going to be one silver bullet that addresses drunk driving. We need to combat it from every possible angle," said Michael Frias, deputy director of the Governor's Office for Highway Safety.

A bill sponsored last year by Rep. Bill Konopnicki, R-Safford, doubled fines for driving under the influence. The new fines, which took effect March 13, call for a $950 assessment for a first conviction and $2,150 for a second one.

A second bill, dubbed Robin's Law, earmarks money to pay for publication of DUI convicts' names in newspapers. Named for Robin Johnson, the wife of a Mesa firefighter killed by a drunken driver, the measure has been approved by the House and faces a full Senate debate, possibly this week. "People make honest mistakes," Konopnicki said, especially social drinkers who think they're not impaired but actually have blood-alcohol readings that exceed the 0.08 percent mark, at which drivers are presumed to be under the influence.
