Officially titled the “Abu Dhabi Street Design Manual – PR 402 (Lighting Section),” this document is the mandatory technical reference for all external lighting works within the emirate’s jurisdiction. Whether you are designing a major highway, a residential backroad, a tunnel, or a public park, compliance with PR 402 is non-negotiable. Failure to adhere to its provisions results in rejected design submissions, failed site inspections, and potential legal liabilities.
