When a driver is subjected to a **breathalyzer test**, they are asked to blow into a device that measures the amount of alcohol in their blood. If the result is positive or there are signs of alcohol consumption, a **second test** is conducted to confirm the initial result. This is a right of the driver, as it allows for verification of the accuracy of the first result and ensures there are no errors in the measurement.

Therefore, the driver has the right to **request a second breath test** if they disagree with the result of the first test. This procedure is part of the measures to ensure fairness and accuracy in the detection of alcohol in drivers.
