Mobile billboards — Guides
Mobile billboards vs static billboards: which is right for your business?
The short answer: a static billboard sells one fixed location to everyone who passes it, on a monthly site rental; a mobile billboard sells the suburb you choose, at a fixed daily rate, with the option to move. For province-wide brand awareness, static sites and gantries win on raw reach. For a local business selling to specific suburbs, the mobile format usually wins on every measure that matters. Here is the comparison in full.
Targeting: a road vs a suburb
A static site is an address. Whoever drives that road sees your board — commuters passing through, traffic to somewhere else, and somewhere among them, your customers. You are paying for all of them.
A mobile billboard is a decision: park outside the shopping centre your customers already use, on the school-run route, at the intersection your suburb crosses twice a day. For a business whose market is three suburbs, that is the difference between broadcasting and aiming.
Cost structure: monthly rental vs daily rate
Static sites are quoted as monthly rentals locked to the location, and they vary enormously — modest suburban boards at one end, six-figure highway gantries at the other. The site's traffic sets the price, not your business's needs.
Mobile campaigns run on a fixed daily rate agreed before you start. Ours are R200 – R285 per day in Gauteng depending on campaign length, including printing, setup, four moves a month, photo reporting and insurance — the full breakdown is in the 2026 cost guide.
Flexibility: a contract vs a schedule
If a static site underperforms, the board waits out the contract — it cannot move. If a mobile position underperforms, the trailer is repositioned; four moves a month are standard, so a campaign works several decision points in a month instead of betting everything on one. Artwork flexibility follows the same pattern: in-house printing turns a new board around in 2 – 3 working days, so specials, phases and countdowns stay current.
Proof: a schedule vs a photograph
Static proof of performance is typically a booking schedule and a drive past. Mobile campaigns — run properly — photograph the board on location after every move, giving you a dated photo trail of exactly where your advertising stood. If you answer to a committee, a franchisor or a sponsor, that difference matters.
Where static still wins
Honesty requires the other column. Static sites win when:
- — Reach is the objective. A premium gantry on a major highway is seen by more people per day than any single trailer position. National brands buying awareness at scale belong there.
- — Permanence is the message. A landmark board held for years becomes part of the landscape — a statement of size that a rotating trailer does not make.
- — The location itself is the strategy — the one site directly opposite your own premises, held forever.
The decision in one question
Ask what percentage of the people who will see the board can realistically become your customers. If the honest answer is "most of them, because we chose the suburb," the mobile format is built for you. If it is "a tiny fraction, but there are millions of them," you are shopping for reach, and static and broadcast formats do that job.

Frequently asked questions
Are mobile billboards cheaper than static billboards?+
Usually, and more predictably — a fixed daily rate against monthly rentals that vary widely by site. But the sharper question is cost per relevant viewer, where suburb-level targeting is the mobile format's real advantage.
Are mobile billboards as effective as static ones?+
For local response — enquiries, walk-ins, mandates — a well-placed trailer typically outperforms a static site the customer's suburb never sees. For mass awareness, high-traffic static sites reach more people.
Can I run both?+
Yes, and larger advertisers do: static for the always-on brand layer, trailers for suburb pushes, openings and seasonal campaigns.
