What is a “breathalyzer test”?
- Correct answer: A test of exhaled air by means of a device that provides information about a person’s blood alcohol level.
- A stress test measuring the air quantity that enters the driver’s lungs while driving.
- A test in which a person exhales into a device that gives information about his lung volume.
- A test performed for new-driver applicants by a family doctor, at the requirement of the Licensing Authority.
Why this is the answer
The correct answer in the official bank: A test of exhaled air by means of a device that provides information about a person’s blood alcohol level.
A breathalyzer test is used to detect driving under the influence of alcohol. The person blows into a device that measures the alcohol in the exhaled air, which indicates the alcohol level in the blood. A police officer may require a driver to take it. It does not measure lung volume or fitness, and it is not part of the medical check for a new licence.
