I feel irresponsible talking about things that are more dangerous behind the wheel than DRIVING DRUNK . . . but you're curious, right?
Here's the latest. Driving when you're EXHAUSTED actually makes you a WORSE driver than driving at the legal alcohol limit.
A study found that if you've been awake 17 hours, it has the same effect on you as a .05 blood-alcohol level. And once you hit 24 hours, it's like you have a .10 blood-alcohol level . . . which is higher than the .08 legal limit.
