A device for determining driver alertness includes a gas sensor for continuously monitoring a driver's exhalations and/or volatile organic compounds emitted from the skin, and an analyzer for extracting at least one volatile biomarker in the exhalations and/or the emitted volatile organic compounds, wherein the biomarker is isoprene, and wherein the analyzer is configured to determine the isoprene concentration over the course of a predefined time period to obtain an isoprene concentration profile, determine peaks in the isoprene concentration profile, such that the alertness of the driver can be determined on the basis of the number of peaks within the predefined time period, and/or determine the driver's alertness on the basis of a frequency analysis of isoprene concentrations within the predefined time period, and/or determine the driver's alertness on the basis of random distributions of isoprene concentrations within the predefined time period.
