Clients often ask us, “How much is too much to drink before getting behind the wheel?” Unfortunately, our answer is always “It’s complicated.”
The simple answer is that “too much” is the amount that causes a breath test reading of .08 or more within two hours of driving. This is the clear cut standard set by law under RCW 46.61.502.
But how is a driver to determine whether he or she is .08 or higher before driving? The fact is that there is no practical way to make this determination with precision.
