2022-08-25: Kenneth Vaughn

Do vehicles need to know the speed limits of other vehicle types (e.g., do cars need to know the speed limit for trucks)? If there is a chance of a benefit and the cost is insignificant and perhaps simplifies the design, does it make sense to allow the sharing?

2022-08-25: Kenneth Vaughn

Should the category be "speed rules" and include advisory speeds or "speed regulations" and only identify regulatory speed limits (with advisories listed as a part of general)? What implication does this have on agencies translating rules prior to stating that they have all rules entered for an area?
