Fleet Decals & Identification Numbers  

Promoting and maintaining brand identity along with DOT rule compliance are two of the main reasons for the use of vehicle number decals by American transportation companies. DOT rules dictate that vehicle number decals must display required information on corporate fleet trucks. Some of this required information includes the US DOT vehicle numbers for each truck as well as the company name and any additional required safety markings. Other fleet number decal features like weather and fade resistant graphics can help companies meet both customer expectations and regulated standards.

U.S. D.O.T. Identification

The US Department of Transportation has numerous rules for commercial trucks to follow, some of which pertain to vehicle identification. Properly displayed fleet number identification decals regularly help transportation companies avoid fines and penalties by staying in compliance with these rules. Commercial interstate carriers in the US must display their unique DOT identification number, as well as the trade name of their motor carrier. The characters on these US DOT decals must contrast with the color of the vehicle and be legible during daylight from a distance of 50 feet. High-quality identification number decals are a simple way to identify vehicles in a fleet.

Decals for Corporate Brand Identity

In addition to easy fleet identification and DOT rule adherence, fleet and vehicle number identification decals are also excellent branding and marketing tools. Commercial logos for branding and identity can be printed on vinyl, engineer grade reflective vinyl or prismatic grade reflective vinyl, all with UV inhibiting over-laminates for durability, moisture and fade resistance. Trucks can act as rolling billboards for transportation companies, and a clearly displayed logo on a decal can provide advertising and brand recognition that is essentially free. LEM’s fade resistant decals can keep your logo visible and looking clean through years of harsh and unpredictable weather.

Operational Labels

Vehicle fleet identification number decals are used by a wide range of industries and sometimes, very specialized decals are needed. You can customize OSHA and ANSI compliant machine warning labels which specify operational instructions and necessary safety procedures for vehicles which have moving parts and controls, including sanitation trucks, bucket trucks, and cranes. Made with pressure sensitive vinyl which has a UV-inhibiting clear over-laminate, these decals can withstand extreme temperatures and are moisture resistant to hold up to power-washing.

Driver Alert Labels

At LEM Products, Inc., we manufacture labels and decals that are specifically designed for the unique needs of transportation companies. OSHA format Wide Turn labels alert drivers to allow extra space for tractor trailers and oversized vehicles that require a larger berth to turn corners. These labels can be sized and cut to conform to the vehicle shapes for optimal positioning and visibility. 


LEM also makes various safety equipment that can reduce accident risk and keep things running smoothly. Conspicuity tapes will provide added visibility for safety. The Federal Motor Carrier Safety Administration (FMCSA) regulation Part 393 Parts and Accessories Necessary for Safe Operation, § 393.11: Lamps and reflective devices, requires retroreflective sheeting on commercial trailers of certain sizes and weights. The retroreflective material gives high visibility, day and night.
