Signals and Lighting Certification Class Materials
The signal and lighting certification class materials are supplementary information used to support the MnDOT Signals and Lightering Certification training and to be used as a resource guide for workers who are involved in the construction of MnDOT traffic signals and lighting systems.
The objective is to provide an overview of the contract documents and review MnDOT’s materials and construction requirements for those kinds of projects. The certification class materials are designed to assist everyone involved in these projects become familiar with the contract documents, construction requirements and their application to projects, so that the location and installation of contract items on all projects is uniform and as maintenance free as possible.
The certification class materials are not intended as a substitute for contract documents. The material presented in the field guide is taken from contract documents. Some of it has been paraphrased and contains information that is based on methods and experience acquired from numerous projects. Improved designs, equipment, special applications and variations in standard requirements may develop after the publication of this field guide and is covered in subsequent contract documents.
