3M 888519021965 Dot Conspicuity Tape White 3x180 in

Product Description

The 3M 888519021965 is a DOT-compliant conspicuity tape designed to increase the visibility of commercial trailers, trucks, and other large vehicles. Constructed from reflective sheeting material, the tape meets federal requirements for retroreflective markings on heavy vehicles. It measures 3 inches wide and 180 inches (15 feet) long per roll, making it suitable for full side-marking runs on standard trailer configurations. Licensed transportation or fleet maintenance technicians typically source and apply this product during annual DOT compliance checks or new vehicle outfitting.

This tape is intended for exterior application on commercial motor vehicles requiring DOT conspicuity markings under FMCSA regulations. Typical installations include trailer side rails, rear underride guards, and body side panels. The white color version is used in combination with red segments to create the alternating pattern required by federal conspicuity standards. One roll provides 15 feet of coverage, which is commonly used for partial trailer markings or supplemental applications.
