Design Guidance
Keep It Simple
Short, succinct wording. Avoid complete sentences — one idea per message reads faster than multiple offers crammed together.
Keep It Big
Large text reads from a greater distance. We recommend characters at least 12" tall so drivers have time to comprehend the message.
Keep It Clean
Avoid thin or script fonts — thin strokes lose legibility at distance. Bold, heavy fonts hold up best.
Keep It Colorful
High contrast between text and background colors is key to a legible, eye-catching message.
