Regulation-Compliant Trailer Marking
Every trailer number decal produced by Same Day Vinyl is designed to meet or exceed FMCSA trailer marking requirements — covering sizing, visibility, placement, and material durability standards.
Sizing Specifications
Federal Motor Carrier Safety Administration (FMCSA) regulations mandate minimum character heights for trailer identification markings. Numbers displayed on trailers must meet minimum 2-inch character height requirements for proper readability at distance.
Visibility Standards
DOT trailer marking requirements specify minimum contrast ratios between character color and background surface. High-visibility colors such as white on dark surfaces and black on light surfaces ensure compliance with FMCSA visibility standards.
Placement Requirements
Identification numbers must appear on both sides of the trailer as specified by federal guidelines. Placement height from the ground, clear of obstructions, and readable without vehicle adjustment are all regulated parameters.
Available Formats & Options
Same Day Vinyl offers a full range of format, color, and finish configurations to match every trailer type and identification requirement. Explore safety and compliance decal options or browse the full vinyl services catalog for related products.

Protective overlaminate prevents fading and color shift from prolonged sun exposure — maintaining legibility and compliance throughout the decal's service life.
