21. クラクション
クラクションは、危険を警告したり、安全上必要な場合に他の道路利用者の注意を引くための音響装置です。多くの自動車ではハンドルから操作する電気式ホーンが装備されています。交通法規では、特に市街地や住宅地で不必要・過度な使用が制限されるのが一般的です。そのためクラクションはいら立ちを表したり挨拶するためではなく、警告装置として使用します。
What is a car horn?
A car horn is a sound-producing warning device used to alert other road users when their attention is needed for safety.
When should you use the horn?
The horn should generally be used when a sound warning is necessary to help prevent danger or an accident. The exact circumstances in which horn use is permitted depend on local traffic laws.
Can you use the horn to show annoyance?
Generally, no. A horn is intended as a safety warning device, and unnecessary or excessive use may be prohibited by local traffic rules.
Can you use the horn at night?
Rules for using the horn at night vary between countries. Some traffic laws restrict sound signals at night and require drivers to use their lights instead, except when there is immediate danger.
Can a vehicle horn be modified?
Vehicle horns may have to meet technical requirements for their sound and operation. Horns that imitate emergency-service sirens or otherwise fail applicable vehicle standards may be prohibited.
Is the horn checked during a vehicle inspection?
In countries with periodic technical inspections, the operation and condition of the horn may be checked as part of the vehicle's safety equipment.
