Just How Does Blood Alcohol Content Affect Your Driving?

We hear a lot about blood alcohol concentration (BAC), but how exactly does it affect our ability to drive?

That may be a tough question to answer since all of us will absorb and metabolize alcohol at different rates. However, with a bit of assistance from The National Highway Traffic Safety Administration (NHTSA), we can see how different BAC levels affect an average person's reflexes.

How is BAC measured?

Our apologies for sounding a bit too technical, but here in the U.S., your BAC is measured by dividing grams of alcohol by 100 milliliters of blood and then converted into a percentage.

In most states, for example, the legal BAC limit is .08%. That means that for every 100 milliliters of blood, there are 8 grams of alcohol in the bloodstream.
