Your brand, on the move — everywhere your audience already drives.
Out-of-home advertising you can actually measure.
Wayside Ads turns the trucks already rolling down America's highways into mobile billboards — every route GPS-verified, every impression modeled from real road traffic instead of guesswork. Traditional OOH gives you an estimate. We give you delivery you can audit.
Illustrative flight, modeled with our live rate card and metering method: 6 trailers · I-95 corridor · 12-week flight · ~200,000 GPS-verified route miles · ~19M modeled OOH impressions
Why Wayside Ads
Billboards can't tell you what they delivered. Ours can.
Every truck streams its real route. We meter exposure against road traffic and population density, dedupe reach from frequency, and bill only modeled, billable impressions you can audit — the accountability of digital, in the physical world.
GPS-verified delivery
Impressions are metered from each truck's actual GPS trail — not a static "estimated daily views" number on a media kit.
Reach & frequency, deduped
We separate how many unique people saw your brand from how many times — so you never pay twice for the same eyeballs.
Pay for what was delivered
Billing is tied to billable impressions, calibrated to what a billboard on that same stretch of road would earn.
Auditable, end to end
Every campaign ships with a proof-of-performance report — GPS-verified routes, modeled impressions, and the methodology behind them — that you can open, check, and share.
The difference
Not all truck impressions are counted the same way
Most truck media quotes you a big daily-views number and a CPM under a dollar. Those numbers are estimated — everyone who might have driven past the truck, counted as a view. Wayside counts differently.
How it works
Highway billboards that come to your audience
Activate the fleet
Fleet owners list their trailers; we handle creative production and installation end to end.
Drive real routes
Trucks run their normal routes through cities and along interstates, streaming GPS the whole way.
Measure & bill
We meter exposure into modeled OOH impressions and bill advertisers on what was delivered.
Measurable reach across the markets that matter
Buy mobile-billboard space by route and region — billed on modeled impressions metered from GPS-verified routes, with a report you can audit.

A higher CPM that costs you less
You'll see truck-media CPMs advertised below a dollar. They're built on estimated daily views — every car that might have passed, counted as an impression. We don't count that way.
Wayside meters exposure from each truck's real GPS trail, models it against the measured traffic on that same stretch of road (AADT), and dedupes reach from frequency. The result is an auditable, billable impression count — and a CPM around $3 where you can see exactly which roads, which traffic, and which methodology produced every impression you pay for.
Pay $0.50 for impressions that didn't happen and you've overpaid. Pay $3 for impressions you can audit and you know exactly what you bought.
How we measure it
Worked example — illustrative month, one trailer
The $0.50 CPM that's really $5
What the flat-rate vendor bills
“50,000 daily views” × 30 days = 1.5M impressions, invoiced at $0.50 CPM.
$750
The same invoice whether the truck drove or not.
What the truck actually did
9 days parked at the depot. Most miles run overnight on near-empty highway. Modeled against the real traffic on those roads: ~150,000 impressions delivered.
$5.00 effective CPM
$750 ÷ 150k real impressions — 10× the sticker price, and invisible, because nothing was measured.
The same month on Wayside
Depot days bill nothing. Empty-road miles bill next to nothing. You pay for the ~150,000 modeled impressions that happened — with the routes and traffic data to audit them.
$450
150k × $3 CPM — less money, for impressions you can check.
The flat “daily views” number never changes; the driving does. When exposure is estimated instead of metered, every parked day and every empty overnight mile gets billed as if it were rush hour.
