- Avoid calquing as "устройство предупреждения опасности" which is overly literal and unnatural. Use "сигнальное устройство", "предупредительная сигнализация", or "аварийный сигнал" depending on context.
- Do not confuse with just 'hazard' or 'warning' alone; the phrase specifies the physical object.
Common Mistakes
- Incorrect article: 'an hazard warning device' (should be 'a hazard...').
- Pluralisation error: 'hazards warning devices' (should be 'hazard warning devices').
- Using it as a verb, e.g., 'They hazard warning deviced the area' (ungrammatical).

FAQ
Frequently Asked Questions
Not exactly. 'Hazard lights' (or 'hazard warning lights') are a specific TYPE of hazard warning device used on vehicles. The broader term can include sirens, beacons, alarms, or electronic alerts in many other contexts.
Typically, no. The term strongly implies a physical, tangible device. A pop-up alert on a computer screen would more naturally be called a 'warning dialog', 'alert', or 'notification'.
A hazard warning device specifically alerts you to a danger. A safety device is broader and can include equipment that prevents harm (like a guardrail), protects you during harm (like a helmet), OR warns you of harm.
No, it is a low-frequency, specialised term. Learners in engineering, technical, or safety-related fields will encounter it, but general English learners are unlikely to need it actively.
