Safe and Efficient Traffic Circulation. The city traffic engineer shall review all proposals for businesses containing a drive-in use. As a guide, the city traffic engineer will utilize those traffic engineering standards as published in the "Rules and Regulations Concerning Permission for the Use of State Highway Rights of Way" by the Rhode Island Department of Transportation, December 14, 1983 as amended. Approval for a drive-in use shall only be granted if the city traffic engineer determines that the drive-in use and its associated operational characteristics will not create a traffic hazard either with respect to traffic congestion, the adequacy and safety of entry and exit points or the on-site vehicular pattern. The city traffic engineer's written approval shall be required prior to certification by the building inspector that the application (for a building permit) is complete.
