Traffic Control Devices Pre-Approval Program
The Virginia Department of Transportation (VDOT) has established a Traffic Control Device (TCD) Pre-Approval Program to evaluate and pre-approve traffic control devices against VDOT standards and specifications.
The program includes both the Traffic Control Device Pre-Approved List (TCDPAL) and the Traffic Control Device Rescinded Product List (TCDRPL).
These lists will be routinely revised and should be reviewed regularly for updates and additions.
The TCDPAL is a list of traffic control devices pre-approved as compliant with current road and bridge specifications, standards and other minimum requirements for use on Virginia streets and highways.
Products on the TCDPAL do not require project-specific review and approval, unless project-specific special provisions, copied notes or plan notes have modified VDOT’s general specifications and / or standards for the product.
Products not listed on the TCDPAL may still be used on VDOT projects. However project-specific review of catalog cut sheets is required.
The TCDPAL serves as a shortcut to this process.
Pre-approved traffic control devices may be rescinded from the TCDPAL and placed on the TCDRPL.
Rescinded traffic control devices are typically those that are obsolete, discontinued or no longer in conformance with VDOT specifications.
Products on the TCDRPL may still be used on VDOT projects. However, they may only be used with project-specific review of catalog cut sheets, submitted in accordance with VDOT road and bridge specifications.
Product application – The process begins with email submission of a completed product application to TCDPre-approvedlist@VDOT.Virginia.gov.
Product evaluation – Upon receipt of the application, VDOT staff will evaluate the product against pre-defined approval criteria.
Evaluation timelines, results and approval decisions will be communicated to the applicant and VDOT staff will address any questions or concerns.
Product monitoring – If approved, the applicant, the product vendor and / or the product manufacturer are expected to proactively notify VDOT of any significant product specification changes.
Failure to do so may result in the product’s removal from the TCDPAL.
At a minimum, VDOT requires resubmission of catalogue cut sheets on a five-year cycle in order to maintain approved status.
VDOT also reserves the right to re-evaluate any or all products as it may deem necessary.
