According to regulations, a vehicle towing a house must not operate during specific hours without carrying certain items. Which is NOT one of those items?

When a vehicle is towing a house, there are regulations in place to ensure safety and visibility on the road, especially during times when visibility might be poor, such as at night or in inclement weather. The requirement to carry items like flares, portable emergency deflectors, or red electric lanterns is crucial for alerting other drivers of the oversized load and ensuring that the towing vehicle is visible.

Having three flares, three red portable emergency deflectors, or three red electric lanterns serves the purpose of enhancing safety and preventing accidents. These items are specifically designed to notify oncoming traffic and provide a clear indication of the vehicle's presence and size.

In contrast, a spare tire is an important tool for regular vehicle maintenance and can be essential for roadside emergencies, but it does not serve the same purpose as the other listed items when it comes to ensuring visibility and safety during the towing of a house. Hence, it is not specifically mandated for the operation of a vehicle towing a house under the outlined regulations.
