Swiss driving theory: the driver must be fit to drive. Alcohol limits (0.5‰ general, 0.1‰ for new drivers and professionals), zero tolerance for drugs, fatigue and medication impair driving fitness.
Alcohol Limits in Switzerland
General limit: 0.5‰ blood alcohol (BAC)
Zero tolerance (0.1‰) for: new drivers (3 years), learners, driving instructors, professional drivers (taxi, bus, lorry)
0.8‰ and above = serious offence – licence withdrawal, fine, possible imprisonment
Drugs and Medication
Zero tolerance for illegal drugs (cannabis, cocaine, heroin, amphetamines, etc.). Even trace amounts in saliva or blood lead to licence withdrawal.
Check the package insert of any prescription medication – some sleeping pills, sedatives and antihistamines impair driving fitness even days later.
Fatigue and Concentration
Driving when tired is comparable to driving with alcohol – reaction time drops sharply
Take a break every 2 hours on long trips
Coffee, music or open windows are no substitute for sleep
Strong emotion, stress and illness also impair the ability to drive safely
