No Universal Design — Every State Is Different
Unlike most highway signs, which follow federal standards for uniformity, roadside memorial signs are state-specific. Each state designs its own sign within the constraints of highway safety — primarily using breakaway mounting systems and reflective materials. The result is a diverse set of designs across the country.
Common Elements Across Most State Signs
Despite the variation, most state memorial signs share these characteristics:
- Reflective sheeting: All official signs use Type III or Type IV retroreflective sheeting for nighttime visibility.
- Breakaway mounting: Signs are mounted on breakaway posts that collapse on impact rather than impaling a vehicle. This is a federal highway safety requirement.
- Victim's name: All programs include the victim's name, though formatting (first name only, full name, initials) varies by state.
- Safety message: Most states include a safety message such as "Drive Safely," "Don't Drink and Drive," "Please Buckle Up," or "Don't Text and Drive."
- Standard dimensions: Most state signs are 24"×30" or similar standardized dimensions. Florida's program uses a distinctive 15-inch round "Drive Safely" marker.
Notable Sign Designs by State
Florida
Florida's program uses a distinctive 15-inch round aluminum sign with "Drive Safely" in the center and the victim's name on a smaller plaque below. The round design is immediately recognizable and different from every other state's program. Color: white with green or black lettering.
Texas
TxDOT uses a standard rectangular sign, typically white with "Drive Safely" and the victim's name in black lettering. The sign meets MUTCD standards for retroreflectivity. After the 2-year term, TxDOT offers the physical sign to the family.
Washington State
WSDOT's signs are rectangular with a distinctive yellow diamond warning sign shape incorporated into some designs. The sign includes the victim's name and a brief safety message. Washington's program, the oldest in the U.S. (1994), has a large inventory of signs that are immediately recognizable to long-term state residents.
West Virginia
WV DOH allows families to choose from four different safety messages for their sign: "Don't Drink and Drive," "Please Buckle Up," "Don't Text and Drive," or "Watch for Pedestrians." This message choice is one of the most flexible in the country.
New Mexico (Descanso Program)
New Mexico's descanso markers are designed to complement the state's cultural tradition of roadside shrines. The official NMDOT descanso is a white cross-shaped marker with the victim's name. The cross design is culturally significant and reflects the Spanish Catholic heritage of the descanso tradition.
South Dakota (THINK Signs)
South Dakota's THINK signs are distinctive yellow diamond-shaped warning signs with "THINK" in large letters and a safety message below. They are designed to function simultaneously as memorial markers and active driver attention signs — meant to make drivers think about safety at the crash location.
Can I Customize the Sign Design?
No. Official state memorial signs are standardized for highway safety. Custom designs, colors, photos, religious symbols, or personalized messages beyond the victim's name and the standard safety message are not permitted. The standardization serves two purposes: highway safety (consistent, recognizable signs) and administrative manageability (states cannot fabricate individual custom signs at scale).
If personalization is important to your memorial, an informal memorial (subject to your state's rules) or a non-roadside alternative such as a memorial bench may offer more options. See our alternatives guide.
