When a tow truck is dispatched, what can be assumed about the situation?

When a tow truck is dispatched, it signifies that a vehicle needs to be removed from its current location. This can occur for various reasons, such as being illegally parked, involved in an accident, or needing mechanical assistance that the owner cannot address on-site. The involvement of a tow truck indicates that the vehicle is not in a secure or acceptable situation and requires intervention for its safe removal.

The other options do not accurately capture the primary reason for dispatching a tow truck. A vehicle being towed does not necessarily imply that it is no longer at risk or that assistance has been refused. Rather, it highlights the need for the vehicle to be taken to a different location, which is the key focus of the tow truck's role.
