But it's veryimportant to keep in mind that the ability to drive is affected well below aBAC of 0.10 percent. Research shows that the driving skills of many people are impaired at a BAC approaching 0.05 percent, and thatthe effects are worse at night. All drivers are impaired at BAC levels above 0.05 percent. Statistics show that the chance of being in an accident increases sharply for drivers who have a BAC of 0.05 percent or above. A driver with a BAC level of 0.06 percent (three beers in one hour for a 180-pound or 82 kg person) hasdoubled his or her chance of having an accident. At a BAC level of 0.10 percent, the chance of that driver having an accident is six times greater; at a level of 0.15 percent, the chances are twenty-five times greater! And, the body takes about an hour to rid itself of the alcohol inone drink. No amount of coffee or number of cold showers will speed that up. "I'll be careful" isn't the right answer. What if there's an emergency, aneed to take sudden action, as when a child darts into the street? A person with a collision. higher BAC might not beable to react quickly enough to avoid the There's something else about drinking and driving that many people don't know. Medical research shows that alcohol in a person's system can make crash injuries worse. That's especially true for brain, spinal cord and heart injuries. That means that ifanyone who has been drinking - driver or passenger - is in a crash, the chance of being killed or permanently disabled is higher thanif that person had not been drinking. And we've already seen that the chance of a crash itself is higherfor drinking drivers. Control ofa Vehicle You have three systems that make your vehicle go where you want it to go.
