Auto repair shop advertising signs: which ones work, what to put on them, and what to check first

The advertising signs that matter most for an auto repair shop are the ones drivers see while they're already near you: the sign on the building, a pole or monument sign by the road, window lettering, and an A-frame or banner for a current offer. Keep each to a few words you can read at the speed of traffic: who you are, what you fix, and a phone number or "open now." Before you buy anything, check your city's sign rules and your lease, because permits, size limits and landlord approval vary and an unapproved sign can be ordered down.

Below: the sign types for a repair shop and what each is good for, what to write, how big the letters should be, the permit and lease checks, a cost-per-month way of comparing them, how to know a sign is working, and mistakes to avoid.

The sign types, and what each does

Sign	Best for	Limits
Building sign (wall or fascia)	Telling drivers on your road that this is a repair shop and its name	Fixed words; changing it costs money; reads best from the front
Pole or monument sign	Being seen from farther along the road, and from both directions	Often the most regulated; may be shared with a landlord's tenants
Window lettering or film	Hours, services, makes, payment types, "walk-ins welcome"	Read by people close by; too much text becomes clutter
A-frame / sandwich board	A current offer, an inspection reminder, "we're open"	Often limited or banned on sidewalks; must not block the path
Banner or feather flag	A short-term message, like a grand opening or "State inspections"	Many cities limit how long and how big; weather wears them
Marquee or LED message sign	Changing offers and seasons	Local limits on brightness and message changes; a stale message looks worse than none
Vehicle lettering or wrap	Your tow truck, loaner car or shop truck as a moving sign	Reaches drivers around town, not just on your road; wraps cost more than lettering
Customer-car window sticker	A reminder of the next service, with your name and number	Seen by the customer, and the people who ride with them
Directional sign	Guiding drivers from a main road to a shop down a side street	Needs permission from whoever owns the land

If your shop sits on a road with little traffic, the building sign and the Google listing do the heavy lifting. If it's on a busy road, a pole sign that reads from a distance may be worth more than any other single thing.

What to put on a repair shop sign

People read a sign in two to three seconds from a moving car. Use three items at most.

Your name and what you are. If your name doesn't say "auto repair," add the words: "Maple Street Auto Repair." Don't make drivers guess.
The one thing that decides it: "All makes," "Subaru and Toyota," "State inspections," "Diesel," "Open Saturday." Choose the one that matches who you want in. If you haven't chosen yet, see how to pick an auto repair shop's target market.
A way to reach you: a short phone number, or your website if it's easy to say. A long web address no one can read in a car is wasted.

Leave out long lists of services, small-print offers, prices that change and slogans. Put those on the window, the website, or a handout. A sign is a pointer, not a brochure.

Make it readable: size, colour and placement

Letter size. A common rule of thumb from sign makers is about one inch of letter height for every 10 feet of viewing distance. Ask your sign maker to work out the size for the speed of your road, and test it by standing where a driver would see it.
Contrast. Dark letters on a light background or the reverse. Avoid thin script, light colours on busy backgrounds and all-capitals paragraphs.
Few words. Fewer, bigger words beat many small ones.
Light. If you're open after dark, light it. An unlit sign works half the day.
Placement. Walk or drive past your own shop at the posted speed from both directions. Are trees, poles, parked cars, or a neighbour's sign in the way? Can drivers see the entrance in time to turn?
Condition. Faded letters, a flickering bulb or a dirty panel say the same about your work. Clean and fix them.

Check permits, the landlord and the HOA before you buy

Almost every city regulates signs, and the rules differ widely. Before paying for anything, do three checks, in order:

Your lease. Many leases say what you can mount, where, and that the landlord must approve. Some shopping centres have a sign standard for all tenants.
The city or county sign code. Search "[your city] sign permit" or call the planning or zoning office. Ask about: size and height limits, whether lit or moving signs are allowed, a permit for new or changed signs, sandwich boards on sidewalks, banners and how long they may stay up, and vehicle signs parked on the street.
Utility and right-of-way. Don't place a sign on a public sidewalk, in a road's right-of-way, or on a utility pole, unless the city says so in writing. Signs placed there can be removed.

A professional sign company usually knows the local code and may handle the permit for a fee, but you're still responsible for your own sign. Keep a copy of every approval.

Compare signs by cost per month

Signs don't have a monthly bill, which makes them look free after the purchase. They aren't. To compare them fairly, work out cost per month over the years you'll use them, and add upkeep.

Total cost: sign, installation, permit, electrical work.
Divide by the months you expect to use it. (Example with made-up numbers: a $3,600 sign used for 10 years is $30 a month.)
Add upkeep: bulbs, cleaning, repainting, any yearly permit fee.
Compare with a month of the other things you could do: our guide on the best advertising for an auto repair shop compares search ads, mailers, signs and social on cost, speed and tracking.

Get written quotes from at least two sign makers; ask what's included (design, permit, install, warranty on the lighting). Prices vary a great deal by size, material and city, so use your own quotes, not a number from a website.

How to tell if a sign is working

A sign's job is to bring in people who'd otherwise drive past. You can check it with simple counts.

Ask at check-in: "How did you hear about us?" Add "saw the sign" as a tick box on the work order.
Count walk-ins before and after a new sign or a new offer on the A-frame, for the same weeks.
Use a different phone number or URL on a sign or a vehicle if you want to separate its calls, but don't use a number that differs from the one on your Google listing for your main business.
Check the other numbers too. If walk-ins rise after a sign change while calls and searches stay flat, the sign is likely the cause.

Give it enough weeks that a single odd week doesn't mislead you.

Signs work best with a good online listing

A driver who sees your sign often looks you up on a phone: the name, the reviews, the hours. If the listing says you're closed when you're open, or the site is hard to read on a phone, the sign's work is wasted. Do these in the same week:

Match the name and phone on the sign to your Google Business Profile. Our auto repair shop SEO guide covers the profile field by field.
Have a page the sign's words lead to: "Subaru repair" on the sign, a Subaru page on your site. If you don't have a site, start with the smallest site worth having.
Put the sign's offer on your Google profile as a post.

The sign is one of several things in your marketing plan; it covers the street, and the others cover search.

Mistakes to avoid

Too many words, in too small letters.
Spending on a sign before checking the permit and the lease.
A sign that doesn't say you fix cars ("Maple Street Motors").
A web address that's hard to read or say.
Prices on a permanent sign. They'll go out of date.
A sidewalk sign that blocks the path, which some cities fine and which can cost you goodwill.
Leaving a bulb or letter dark. It can make the shop look closed.
Promises you can't keep: "Fixed same day," "Cheapest in town."

FAQ

What are the best advertising signs for an auto repair shop?

A clear building sign and, if your road is busy, a pole or monument sign are the base. Window lettering and an A-frame for current offers are cheap additions.

What should an auto repair shop sign say?

Your name, that you're auto repair, one deciding fact (makes, inspections, hours) and a phone number. Three items at most.

Do I need a permit for a shop sign?

Often, yes, for new or changed signs, and for some banners and sidewalk boards. Rules differ by city, so check with your planning or zoning office and your landlord before you buy.

How big should the letters be?

Sign makers often use about one inch of letter height per 10 feet of viewing distance. Ask yours to size it for the road's speed.

Are signs worth it compared with online ads?

They're cheap per month and always on, but they reach only people who pass you. Online ads and search reach people looking for a shop. Most shops use both.

Can a sign be put on a vehicle instead?

Yes. Lettering on a tow truck, loaner or shop truck moves your name around town. Follow the same rules: short words and a number.

A sign gets the driver to look you up, so the page they land on matters. Email us your shop's name and we'll send a free homepage preview built from what you already publish. More guides are on the auto repair guides page.
