Commercial or municipal sign manufacturers who wish to obtain Department approval to manufacture signs shall request an application from the Bureau of Highway Safety and Traffic Engineering. Only signs manufactured by the Department or a Department-approved sign manufacturer shall be used on any highway. Variations in the proportion of symbols, stroke width and height of letters, width of borders or layout of word or symbol messages will be sufficient cause for the Secretary to order the removal or replacement of a sign, but will not be a defense in prosecution for violation of any mandatory traffic control provided by the sign. Official signs must replace existing signs of nonstandard design or application as rapidly as is economically feasible. When approved by the Secretary, through the Chief, Traffic Engineering and Operations Division, these signs shall also be regarded as official signs. When sign messages are required other than those provided for in the Pennsylvania Handbook of Approved Signs, the Bureau of Highway Safety and Traffic Engineering may authorize new sign standards. Official traffic signs are identified in the Pennsylvania Handbook of Approved Signs (Department Publication 236M) which includes sign standards that show the shape, color, dimensions, legends, application and placement of official signs. Recreational and cultural interest area signs. No Turn on Red Sign (R10-11 sign series). Stopping, standing and parking restrictions.

Additional warrants for Stop Signs (R1-1) and Yield Signs (R1-2).

No passing zone sign name
