Which term describes a vehicle that is unable to operate due to mechanical failure or other issues?

The term "disabled vehicle" refers to a vehicle that is unable to operate because of mechanical failure, accidents, or other issues that render it inoperable. This term is commonly used in law enforcement and emergency response contexts to indicate that a vehicle is not functional and may pose a hazard or require assistance on the road. It emphasizes the condition of being incapacitated or unable to perform the primary function of driving, which is crucial for understanding situations that involve vehicle stops, accidents, or roadside assistance.

While the other terms might convey similar ideas, they lack the specific connotation of "disabled" that is widely recognized in traffic enforcement and emergency response sectors. "Faulty vehicle," for instance, suggests a broad range of issues but does not explicitly indicate that the vehicle cannot be driven. "Inoperable transport" and "malfunctioning auto" are less commonly used phrases that may not be as easily understood in everyday language or official documents. Therefore, "disabled vehicle" is the most appropriate and universally understood term in this context.
