Alcohol test - breath
There are no risks.
The test does not take into account the driving abilities of the test subject. Driving abilities vary among people with the same blood-alcohol levels. Some people with blood-alcohol levels below 0.05% may not be able to safely drive. For occasional drinkers, judgment problems occur at blood-alcohol levels of just 0.02%.
The breath alcohol test helps you to know how much alcohol it takes to raise the blood-alcohol level to a dangerous level. Each person's response to alcohol varies. The test may help you make better decisions about driving after drinking.
