Ad design guide

Design a Mobile Billboard Ad People Can Read in 3 Seconds

People see a moving truck for a moment. These rules make that moment count. Our sales team gives you the exact aspect ratios and file type, and our designers can build the artwork for you.

See the difference

Same business. Two very different ads.

Flip the switch and compare what a driver can actually take in.

Two lines. Readable from across the lot.

The six rules

What works on a moving screen

  1. One message

    Pick the single thing you want remembered: who you are, what is happening, or what to do next. Not all three in small type.

  2. Seven words or fewer

    A rule of thumb for anything read from a moving car. If it takes longer than a glance, it will not be read.

  3. Big type, high contrast

    Light on dark or dark on light. Thick letters. Skip thin fonts, script fonts and text over busy photos.

  4. One call to action

    A short web address, a phone number or a QR code. Choose the one that fits where the truck will be seen.

  5. Name always on screen

    Lead with the offer or the event, but keep your business name on screen the whole time, big enough to read across a parking lot.

  6. Design for three screens

    Both sides and the rear show your ad. The rear screen is seen longest by the driver behind, so it can carry a little more.

What you can show

Graphics, video, live streams and sound

  • Graphics: Text, Images, GIFs
  • Video: Commercials
  • Live Streaming: TV Shows, Sports
  • DJ Soundsystem: Microphone + Speakers

Motion gets noticed, but keep the key message still or slow enough to read. With the LED trucks it’s easy to switch up the messages or images during your campaign, so bring more than one version.

Designing ads for both sides and the rear screen usually costs $395 to $695. The VIP Prime Package adds a 30-45 second professional commercial video and monthly graphic designs.

Before you send your artwork

  • Can a stranger read it in three seconds?
  • Does it still read with your eyes half closed (contrast check)?
  • Is there exactly one thing to do next?
  • Is the business name large and spelled out?
  • If it moves, does the key message stay on screen long enough to read?
  • Do you have a second version ready to swap in mid-campaign?
