How Inadequate Signage Gets Parking Tickets Cancelled
When Car Park Signs Are Not Good Enough
Private parking charges are based on contract law. The contract is formed when a motorist enters a car park and agrees to the terms displayed on signs. But if the signs are not adequate, there is no valid contract and the parking charge is unenforceable.
Signage defects are one of the most successful grounds for appeal and our AI finds them in a significant number of cases.
What the Law Requires
Under the BPA Code of Practice and general contract law principles, parking signs must meet several requirements:
- Prominent and visible. Signs must be positioned where a reasonable motorist would see them before parking. A sign hidden behind a bush, placed at an unusual height, or facing away from incoming traffic is not adequate.
- Legible. The text must be large enough to read from a reasonable distance. Small print, faded lettering, or signs covered in dirt may not be sufficient.
- Clear and unambiguous. The terms must be easy to understand. Contradictory information, confusing layouts, or legal jargon that a reasonable person would not understand can undermine the contract.
- At the point of entry. The motorist must have the opportunity to see the terms before committing to parking. Signs located only inside the car park or at exits are not sufficient to form a contract.
- Consistent. If there are multiple signs with different terms, the contract may be void for uncertainty. This is common in large car parks where signs have been updated at different times.
Common Signage Defects We Find
Obscured or hidden signs
Vegetation, other vehicles, or structural elements blocking the view of the terms. If you could not reasonably see the sign, you could not agree to the terms.
Contradictory information
Different maximum stay times on different signs. One sign says 2 hours free, another says 3 hours. This creates uncertainty about the actual terms.
Missing key information
The sign does not state the parking charge amount, the grace period, or the appeal process. The BPA Code requires specific information to be displayed.
Poor positioning
Signs placed too high, too low, facing the wrong direction, or only visible when leaving the car park.
Faded or damaged signs
Weathering, vandalism, or age rendering the sign illegible.
How to Use Signage in Your Appeal
If you believe the signage at the car park was inadequate:
- Take photos of all signs at the location, including their position relative to the entrance
- Note any obstructions, damage, or inconsistencies
- Upload your parking charge notice to our AI PCN Manager
- Mention the signage issue when prompted for additional information
Our AI incorporates signage defects into the appeal letter with specific references to the BPA Code of Practice requirements.
Key Case Law
The Supreme Court case ParkingEye Ltd v Beavis [2015] established that parking charges can be enforceable, but only where the terms are clearly displayed and the charge is proportionate. Inadequate signage undermines the first requirement.
