noun
vehicle with a running engine; operational vehicle
Refers to a car, motorcycle, or similar vehicle whose engine is actually running, as opposed to one that is turned off or non-functional. Often used in contexts like traffic counts or fleet management.
駐車場には実動車が数台止まっていた。
There were several vehicles with their engines running in the parking lot.
交通量調査では実動車の台数を数えた。
In the traffic survey, they counted the number of operational vehicles.
稼働車 emphasizes a vehicle that is in service or working (e.g., a taxi on shift), while 実動車 specifically means the engine is running.
Compound of 実 (actual) + 動 (move) + 車 (vehicle). The exact origin is uncertain, but it likely arose in technical or administrative contexts to distinguish vehicles with engines running from those that are stationary or out of service.
