This feels like a question in semantics, but I'm going to throw it out there anyway. I'm working on a project for the Department of Transportation, and they are planning on providing signage for preferred spots for High Occupancy Vehicles (HOV). The signage will specifically read 'Reserved HOV Parking Only.' In the particular state where this project is located, HOV is generically defined as a vehicle containing two or more passengers. Similarly, a carpool vehicle is effectively two or more passengers sharing a ride in a single vehicle. In essence, they are effectively the same. However, I have in the past experienced reviewers who are excruciatingly particular about the wording on signage. In this particular scenario, do you think HOV preferred signage meets the credit criteria and will suffice as carpool preferred signage?
