The aim was of the work to determine the influence of alcohol - present 11° beer - on reaction time to acoustic and visual stimulus for middle-aged men. The research group had 8 people aged 31 to 41 years. For measuring alcohol in breath was used alcohol tester Dräger 7410. Reaction time was measured using reaktometer measurent accuracy to 1 millisecond. To significant increase in average reaction time was at 0.40 per mille alcohol level in breath after drinking three beers. To increase of reaction time at the initiative of sound from 236 ms to 247 ms - 11 ms, significant increase was at the initiative of the optic of 294 ms to 459 ms - 165 ms. After drinking the fifth pint of served beer (0.66 per mille of alcohol in the breath) it was registered continuing increase of reaction time at the initiative of the sound of the original values of 236 ms to 276 ms - 41 ms, at the initiative of the optical surge, against defaults without the presence of alcohol in breath to 515 ms from 294 ms value - an increase of 221 ms. Alcohol already in relatively small amounts has a significant influence on the change of reaction time. Seemingly small increase of the reaction time may have in critical situations immense consequences.
