Which call indicates that assistance is needed to transport a vehicle?

The choice indicating that assistance is needed to transport a vehicle is "Tow truck needed." This phrase directly communicates the necessity of having a tow truck to assist with the transportation of a vehicle, whether it is due to a breakdown, an accident, or needing to move it from one location to another.

When a call states that a tow truck is needed, it clearly signifies that specialized assistance is required to safely and effectively transport the vehicle to the desired destination. This language is commonly understood in the context of emergency services and helps responders identify the specific nature of the assistance required.

In contrast, terms like "Automobile emergency" or "Car towing request" may imply a need for help, but they lack the explicit focus on the towing aspect as seen in the correct answer. Similarly, "Vehicle transport service" could refer to a broader range of services that may not specifically indicate a need for immediate towing assistance. It's the precision of the phrase "Tow truck needed" that makes it the most appropriate choice for indicating that a vehicle transport is necessary.
