221. アルコール検査
アルコール検査は、運転者が飲酒しているか、法定上限を超えているか確認する路上検査です。警察はスクリーニング装置、呼気検査、精密呼気分析、場合によっては血液検査を使用します。手順と法定値は国によって異なります。通常、運転者は権限ある検査へ協力する必要があり、適法な検査を拒否すること自体が処罰対象となる場合があります。
What is an alcohol control?
An alcohol control is a police check used to determine whether a driver has consumed alcohol and whether the applicable legal limit has been exceeded.
How is alcohol tested at the roadside?
Police commonly use a breath-testing device. Depending on the result and local procedure, a more precise breath analysis or blood test may follow.
Can police test a driver who does not appear drunk?
In many countries, yes. Police may conduct random or routine alcohol checks without first observing obvious signs of intoxication.
Can you refuse an alcohol test?
Rules vary by country, but refusing a legally required alcohol test can itself be an offence and may result in penalties or an immediate driving restriction.
Can a blood test be used to measure alcohol?
Yes. A blood test may be used when breath testing is impossible, disputed or required by the applicable legal procedure.
Can you be prevented from driving after an alcohol control?
Yes. If the result exceeds the applicable limit, authorities may impose an immediate temporary driving prohibition in addition to any later fine, licence suspension or court proceedings.
