When approaching an intersection with a contractor's sign indicating a detour, it is important to reduce speed and prepare to follow the alternate route provided. The presence of the detour sign alerts drivers that the normal traffic flow has been altered due to construction or road maintenance, requiring some level of modification to their driving behavior.

By reducing speed, drivers can adjust to the changing traffic conditions safely and remain in control of their vehicle as they navigate through or around the construction area. Preparing to detour helps ensure that the driver is aware of the new direction they will need to take and can do so without causing confusion or hazards to themselves or other road users.

In contrast to the other options, continuing through the intersection disregards the detour instructions, which can lead to unsafe situations. Stopping and waiting for instructions may not be practical or safe in a dynamic traffic environment; it could contribute to traffic congestion or impede other drivers. Finally, sounding the horn would not help in this situation, as it does not convey useful information and may add to distractions or hazards in the work zone. Following the guidelines provided by the contractor's sign ensures safety and compliance with the road work regulations.
