Our USDOT stickers combine your information onto one die-cut adhesive vinyl decal so you don't have to worry about lining each number and letter up as you apply it to your vehicle. The combo decals we offer come with single to multiple lines and are pre-spaced for easier application. All of our US DOT Combo stickers come with a free squeegee to aid you in the application process. In addition to Free shipping, you can relax when you go to install them because we also offer an "oops" policy! So don't fret, if you make a mistake when installing your decal, we will send you the replacement letters that you need for free, you would only pay for the shipping on the replacements. All of our vinyl decal products are produced using 7-year vinyl graphics that are made in the USA.
