Car advertising vs billboards: how do cost and reach compare?
A billboard runs $1,500–$30,000+/mo for one fixed spot. Car advertising plans start at $500/mo and move through the neighborhood instead.
A static billboard typically costs $1,500 to $30,000+ a month for one fixed location, with a cost-per-thousand-impressions (CPM) around $3–$10, based on media-buyer industry pricing. Car advertising through Lunar (lunarcar.me) starts at $500 a month and puts a business's decal on multiple local drivers' cars, each moving through the neighborhood it actually serves — with a single vehicle estimated to generate 30,000–70,000 impressions a day, according to OAAA industry benchmarks. The short version: a billboard reaches whoever passes one spot. Car advertising reaches whoever crosses paths with several different drivers' everyday routes.
How does the cost of a billboard compare to car advertising?
Static billboard pricing varies enormously by market and location — a small-town board might run $1,500/month, while a high-traffic urban placement can hit $30,000+/month, with an outdoor-industry CPM of roughly $3–$10 (media-buyer sources). Lunar's plans for local businesses start at $500/month for Crescent (about 3 cars), $1,000/month for Half Moon (about 7 cars, sticker fee waived), and $2,000/month for Full Moon (about 16 cars, sticker fee waived, premium zones). Plans run in committed 3, 6, or 12-month phases but bill monthly — never the full term upfront. Both formats sell estimated impressions, modeled the same way billboards have always been sold, and neither promises a fixed number of views. That's standard across the whole out-of-home (OOH) industry, billboards included.
How does reach differ between a fixed billboard and a moving car?
A billboard's reach is the traffic that passes one intersection or stretch of highway, day after day. Car advertising's reach is built from many individual routes — the average US driver covers about 31 miles and 2.44 trips a day, according to the AAA Foundation's 2024 American Driving Survey. A handful of local drivers carrying the same decal don't just repeat one route; they collectively cover the grocery run, the school drop-off, the commute, and the errands that make up a neighborhood's actual traffic pattern. One billboard shows up in one place. A small local fleet shows up in several.
Which format actually gets noticed?
A 2019 OAAA and Nielsen study found 64% of US residents 16 and older noticed a wrapped vehicle in the past month, and 44% in the past week — ranking vehicle wraps the most-noticed moving OOH format measured. Separately, a single advertised vehicle is estimated to generate 30,000–70,000 impressions a day, per OAAA industry figures. An older, frequently cited 3M-sponsored study (the 'Snapple' fleet study) put vehicle-ad recall at 97% versus 19% for stationary ads — that number is marketing-sourced and should be read directionally rather than as an audited industry figure, but it points the same direction as the harder Nielsen data: people notice moving vehicle graphics more than they notice fixed signage.
Does a parked car still count as advertising?
Yes — this is where car advertising's reach compounds rather than pauses. A typical urban arterial street carries roughly 18,000 to 20,000-plus vehicle passes a day, per standard traffic-engineering (Highway Capacity Manual) benchmarks, so a car parked on a busy street or in a visible lot keeps collecting views the whole time it sits there. Combined with the impressions generated while it's actually driving, the decal is working in both states — moving traffic and parked visibility — in a way a billboard, permanently fixed in one spot, can't add to.

Which is more flexible if your target neighbourhood changes?
A billboard lease locks a business into one physical location for the term of the contract — moving means renegotiating or waiting out the lease. Lunar plans are built around a target zone the business sets (its neighborhood or service area), and cars are matched inside that zone. The dashboard shows active cars, verified mileage, and estimated impressions for that specific area, and if a spot sits empty mid-campaign, that slice of the plan is credited back. That makes it easier to concentrate reach exactly where customers are, rather than paying for a fixed structure that may or may not still be the right corner.
What does this reach actually mean for drivers?
The impressions above come from ordinary people's ordinary routines, not a media company's fleet. Drivers who join Lunar earn a flat $83.50 base per sticker per month, up to a $100.20 ceiling with bonuses, for driving they're already doing — no shifts, no schedule change. A car has up to four door-sticker spots, so drivers who fill multiple spots typically earn $334–$400 a month. Joining is free, and payouts arrive monthly via Stripe. Earnings are estimates, not guarantees, and depend on matches available in a driver's area.
So which one should a local business choose?
Billboards still make sense for businesses that need premium visibility at one high-traffic location — a highway on-ramp before a stadium, for example — and have the budget to sustain $1,500–$30,000+ a month. Car advertising tends to make more sense for a business whose customers live in a specific neighborhood and whose budget sits in the $500–$2,000 range: instead of paying for one static spot, that budget puts the brand on multiple residents' cars moving through the streets, driveways, and parking lots those customers actually use. Both are forms of out-of-home advertising sold on estimated impressions — the real difference is whether a business needs one fixed location or broad coverage of a specific area.
Frequently asked questions
Is car advertising cheaper than a billboard?
Generally, yes — Lunar's plans start at $500/month for about 3 cars, compared with $1,500 to $30,000+ a month for a single static billboard, based on media-buyer industry pricing. The exact savings depend on the market and the billboard location being compared.
Which reaches more people, a billboard or car advertising?
It depends on the location. A billboard on a major highway can see very high traffic; a single advertised vehicle is separately estimated to generate 30,000–70,000 impressions a day (OAAA). Car advertising's advantage isn't necessarily volume at one spot — it's spreading that reach across several different routes inside one neighborhood instead of concentrating it at one fixed point.
Are car advertising impressions a fixed, promised number?
No. Like billboards and the rest of the out-of-home industry, car advertising impressions are estimates modeled from data such as verified mileage, not a promised or fixed count. Lunar's dashboard reports estimated impressions for exactly this reason.
Does a parked car still advertise for a business?
Yes. A car parked on a typical urban street sits in front of roughly 18,000 to 20,000-plus vehicle passes a day based on standard traffic-engineering benchmarks, so the decal keeps working whether the car is moving or sitting in a driveway, lot, or curb.
Can a business switch its target area the way it could move a billboard?
It's generally easier with car advertising. Lunar plans are built around a business-defined target zone, and cars are matched inside it; a billboard usually requires waiting out or renegotiating a lease to change location.
