General Rule of Uniformity states what?

• A. This subtitle applies uniformly throughout this state. A local authority may not enact or enforce an ordinance or rule that conflicts with this subtitle unless expressly authorized by this subtitle. However, a local authority may regulate traffic in a manner that does not conflict with this subtitle.
• B. Local authorities may freely conflict with this subtitle as needed.
• C. The subtitle does not apply uniformly anywhere.
• D. Local authorities may regulate traffic in any manner, regardless of this subtitle.

Answer: (A)

Uniform application means the provisions of this subtitle apply the same everywhere in the state, and local authorities may not enact or enforce rules that conflict with it unless the subtitle explicitly allows it. As long as a local rule doesn’t contradict the subtitle, local jurisdictions can regulate traffic within those bounds. This keeps traffic rules consistent for everyone and prevents a patchwork of conflicting local rules. If a rule explicitly permits a local variation, that exception would apply, but without such authorization, the statewide subtitle takes precedence.
