How long does (4oz) of alcohol take to clear your system for a alcohol breathe test? Is it the same amount of time as a urine test? (4 days)

No. A breath test will clear in 4-5 hours based on what you drank, typically 1oz. per hour. However, 1 oz. doesn't tell the story since it could be beer, wine, low or high proof drink.
