There is no single universal list of required signs for an EV charging space. What is required for your site arrives in layers: the traffic and parking rules for the land the bay sits on, any funding programme’s written terms, the accessibility rules that govern the site, and — below those, and not law at all — your own posted terms of use. This page shows how to work out which layers apply to a given site, because a sign copied from another car park can be wrong in every layer at once.
Key Takeaways
- “Required” signage comes in layers: land and traffic rules, programme terms, accessibility rules.
- Your own posted terms are a fourth layer — not law, but the layer drivers actually follow.
- Determine the stack for the site: land status first, programme terms second, authority confirmation before painting.
- No size, symbol or wording transfers from another site; every value is read from its own governing text.
The Layers That Can Require a Sign
| Layer | Who writes it | What it can govern | Where to read it |
|---|---|---|---|
| Land and traffic rules | The local authority for the road or car park | Whether the bay is a charging bay at all, its marking, and who may enforce it | The authority’s current parking and signage text for that jurisdiction |
| Funding programme terms | The programme funding the installation | Operating duties the site must show it meets — for U.S. NEVI corridor stations: 24/7 opening, contactless payment with no membership, average uptime above 97% | The programme’s current rulebook — for NEVI, 23 CFR Part 680 |
| Accessibility rules | National or local accessibility codes | Which bays are accessible, their symbols and the access route beside them | The code for the jurisdiction, confirmed with the authority having jurisdiction |
| Your own terms of use | You, the operator | Stay limits, move-when-finished, idle fees if any, help contact | Your decision — posted at the bay, and matched to the charger’s access control |
Only the first three layers can make a sign required. The fourth is still the one drivers read day to day, which is why our guide to how commercial charging stations work treats posted terms as part of the station, not decoration. Confusing the layers causes the commonest error: a restriction worded as if it were law when it is only the operator’s term — or a legal duty left off because nobody read the programme terms.

How to Determine What Applies to Your Site
- Establish the land first. A bay on a public road, in a municipal car park and on private land answers to different texts. This one fact decides which authority to ask.
- Read the funding terms, if any. If a programme paid for part of the site, its current rulebook lists duties — payment methods, hours, reporting — that signage often has to reflect.
- Ask the authority before painting. Bay colours, symbols, sizes and wording are set by the governing text for the jurisdiction. Confirm them with the authority having jurisdiction at design stage; no figure from another site transfers.
- Keep the charger’s own label out of it. The rating label is the manufacturer’s compliance surface — see rating labels and required markings. Site signs do a different job.
Required vs Expected
Some signs are required by no rule and still expected: entrance wayfinding, a help contact at the charger, and bay numbers matching the app listing exactly. On a dual-connector unit such as the EV-AC03201T dual-connector AC station (two Type 2 connectors, up to 43 kW shared, OCPP 1.6J, RFID, IP54), bay-to-connector naming must be identical on the ground, on the cabinet and in the app, or drivers start sessions on the wrong connector. Its 7-inch touchscreen is the session display, not a payment terminal, so signposting must also point to where payment happens. Wallboxes such as the EV-ACT3204PE (22 kW, Type 2, RFID and app, IP66) carry the start instructions at the unit instead. The full range is on the commercial EV charging page.

Frequently Asked Questions
What size do charging bay signs and markings have to be?
This page gives no figure, deliberately. Dimensions, symbols and placement come from the current text governing your jurisdiction — read them there and confirm them with the authority before ordering signs.
Does a private workplace car park need the same signs as a public one?
Not necessarily. On private land the traffic layer is usually thinner, but programme terms and accessibility duties can still apply, and your own terms still need posting. Work through the same layers; the answers differ.
Can we reuse the signs from our last site?
The element list, yes; the values, no. Rules, programme duties and tariffs change, and a different site can sit in a different layer stack entirely. Re-read every value for the new site.
