Key Elements Usually Regulated

• Required automatic dimming or reduced brightness after specified hours.
• Rotation and transition rates (how often content may change and whether animation is allowed).
• Permit categories: new sign permits, replacement/alteration permits, and variances.
• Restrictions near sensitive receptors such as residential zones or roadways to prevent driver distraction.
