How does trailer advertising work in South Africa?

Trailer advertising is the simplest form of outdoor advertising to understand: your ad is printed large, mounted on a purpose-built trailer, and parked where the traffic is. No airtime schedules, no bidding platforms, no algorithm. Yet most business owners who ask us about it have the same practical questions — who parks it, is it legal, what does it really cost — so this is the whole process, start to finish.

Step 1: You choose the suburb, not a site

With a static billboard you rent a specific structure and hope your customers drive past it. Trailer advertising works the other way around: you tell the operator which suburb your customers live and shop in, and the trailer goes to them. At Simply Visible we cover sixteen suburbs across Gauteng, and within each one we maintain relationships for high-traffic positions — shopping centre approaches, school-run intersections, arterial roads.

A good operator will ask what you are trying to achieve before talking about spots. A store opening wants maximum eyes in a two-kilometre radius; an estate agent wants the same three streets seen every day for months. The positions should follow the objective.

Step 2: Printing, artwork and the boring-but-critical checks

Your artwork is printed in large format — ours is done in-house in two to three working days — and mounted on the trailer. Before anything is printed, the copy should be checked: a board is read in about three seconds from a moving car, so one clear message and a phone number beats five bullet points every time. We review every board against the AIDA framework before it goes to print, because around 80% of a campaign’s result comes down to what the board says.

Legal placement is the operator’s job, not yours. Municipal by-laws govern where advertising trailers may stand, and reputable operators handle positioning and any permissions as part of the service. If a quote is suspiciously cheap, this is usually the corner being cut.

Step 3: The trailer parks, moves, and proves it

Once live, the trailer stands in its position day and night — a 24-hour board at eye level. The mobile part matters: our campaigns include four repositions a month, so the same budget works the morning commute one week and the weekend shopping rush the next.

Ask any operator one question before signing: how do I know the board is actually out there? The honest answer is photographic proof. Every time a Simply Visible trailer moves, the client receives a photo of the board on location. If an operator cannot offer that, you are buying a promise, not a campaign.

What it costs and how fast it starts

In Gauteng, trailer advertising with Simply Visible runs from R200 to R285 per day depending on commitment length — roughly R6,000 to R8,550 a month — including printing, setup, insurance, repositioning and photo reporting. Most campaigns are live within three working days of artwork approval. Compare that with static billboard sites, which are quoted per structure and can run from a few thousand rand to six figures a month, before printing.
