Final answer:
The correct answer is option 3) Owner's insurance.The unnecessary information for dispatching towing and recovery units is the owner's insurance.
Step-by-step explanation:
When dispatching towing and recovery units, the information that is not necessary at the initial stage is the owner's insurance. It is more critical to know the specifics about the vehicle and the situation to ensure the correct equipment and services are dispatched. This includes the year, make, model of the vehicle (1), which helps in identifying the vehicle and ensures the right size of tow truck is sent. The type of tow (2) is required to understand the nature of the situation, whether it requires a flatbed, a wheel lift, or another kind of tow truck.
The DOT classification (4) helps determine if there are any special requirements for the tow, especially for commercial or heavy-duty vehicles. Lastly, the vehicle location (5) is essential to provide the service in a timely and efficient manner. Information about the owner's insurance is generally required later in the process, particularly for billing purposes or if there are any claims to be made post-recovery.
