To curb drunken driving, the federal National Transportation Safety Board has voted to recommend that states tighten the legal limit for drivers' blood alcohol.

The threshold now for drunken driving is a blood alcohol concentration of 0.08. (The BAC equals alcohol divided by the volume of blood it's in.)

The NTSB would push for it to be lowered to 0.05, in line with the limits in countries such as Denmark, the Philippines and Switzerland.

Almost half of teenagers cop to texting while driving. And those texting teens are more likely to make other risky moves while in the car, too.

That includes not wearing seat belts, drinking and driving, and riding with a driver who's been drinking, a study just published in the journal Pediatrics finds.

Car crashes have long been the leading cause of death for teenagers, even before texting entered the scene.

Faced with lingering safety concerns over the San Francisco-Oakland Bay Bridge's new eastern span, California transportation officials say it will take more work — and up to $10 million — to get the bridge ready for its planned grand opening on Labor Day.

They discovered the problem after massive steel bolts were tightened to anchor part of the bridge's seismic safety system. Of the 96 that were tightened, 32 broke.
