What characteristic must signage have according to the regulations?

The requirement for signage to be easily visible and readable from the road is rooted in ensuring that it effectively communicates to potential customers as they approach the dealership. This visibility is crucial for drawing in traffic, especially in competitive markets where multiple businesses vie for the attention of passersby. Regulations often emphasize practicality and safety; therefore, signage must not only be aesthetically pleasing but also functional. Being readable means using appropriate size, font, and contrast that can be seen from a distance or while driving. This kind of clarity helps ensure that information about the dealership is accessible to all potential customers, facilitating better business opportunities.

The other characteristics listed, while they may enhance marketing efforts, are not mandated by regulations; thus, they are not necessary for compliance. Ensuring visibility and readability is paramount in the context of driving safety and business effectiveness.
