Regulations of Connecticut State Agencies
(a) The sign dimensions prescribed in these regulations shall be standard for application on public highways. Increases above these standard sizes are desirable where greater legibility or emphasis is needed.
(b) In expressways and freeways, special designs or large signs are prescribed. In the enlargement of signs, standard shapes and colors shall be used and standard proportions shall be retained insofar as practicable. Wherever practicable, the overall dimensions of the sign plates should be increased to 6-inch increments.
