Kaffeetrinkende Trucker haben weniger Unfälle. Fand eine australische Studie mit dem unsexy Titel "Use of caffeinated substances and risk of crashes in long distance drivers of commercial vehicles: case-control study" raus. Aber lies selber:

Results

Forty three percent of drivers reported consuming substances containing caffeine, such as tea, coffee, caffeine tablets, or energy drinks for the express purpose of staying awake. Only 3% reported using illegal stimulants such as amphetamine (“speed”); 3,4 methylenedioxymethamphetamine (ecstasy); and cocaine. After adjustment for potential confounders, drivers who consumed caffeinated substances for this purpose had a 63% reduced likelihood of crashing (odds ratio 0.37, 95% confidence interval 0.27 to 0.50) compared with drivers who did not take caffeinated substances.

Conclusion

Caffeinated substances are associated with a reduced risk of crashing for long distance commercial motor vehicle drivers. While comprehensive mandated strategies for fatigue management remain a priority, the use of caffeinated substances could be a useful adjunct strategy in the maintenance of alertness while driving.

P.S. Dass laut der Studie in Australien unter den unfallfreien Truckern nicht nur das Kaffeetrinken deutlich weiter verbreitet, sondern auch der Konsum von Speed, Ecstasy oder Koks doppelt so häufig ist, wie unter Unfallfahrern, sollte hierzulande der Beratungsstelle für deren Verhütung BFU vielleicht zu denken geben. Oder doch nicht?
