schema of the experimental protocol. The participants remained the first 30 min of the session under dim light, while they carried out the baseline subjective scales and PVT, followed by 5 min of driving practice and 10 min of baseline driving. After that, one of the lighting conditions (blue-enriched white – BWL – or dim light – DL –) was applied while they drove for 60 min. Finally, they performed the PVT and subjective scales for a second time in dim light.
