When a Medical Emergency Isn't Enough: The Bexley Zigzag PCN Case That Every Driver Should Read

A Scenario Most of Us Would Never Expect to Face

Picture this: you're driving your partner to the GP. Halfway there, they clutch their chest and say something is very wrong. You pull over in a panic — not thinking about road markings, not checking whether you're on a zigzag — just trying to help the person you love through what might be a life-threatening moment.

You'd expect any reasonable authority to understand. Surely a potential heart attack is the very definition of an emergency? Surely no adjudicator would uphold a fine in those circumstances?

As this case from the London Borough of Bexley demonstrates, the answer is far more complicated than most drivers would assume. And the lesson it contains could save you from a very costly mistake.

The Case: A Potential Heart Attack and a Pedestrian Crossing

The driver — let's call her the appellant — was travelling with her partner to a GP appointment when he began experiencing chest pain and tightness. Fearing he was having a heart attack, she stopped the vehicle on a section of road marked with zigzag lines adjacent to a pedestrian crossing.

Zigzag markings are the distinctive black-and-white striped lines you see approaching pedestrian crossings — Zebra, Pelican, Toucan, and Puffin crossings all have them. Stopping on these markings is a specific traffic contravention in London, enforced under the Traffic Management Act 2004 and associated regulations. The council issued a Penalty Charge Notice (PCN) for "stopped on a pedestrian crossing or zigzags."

The driver appealed. She explained what had happened: her partner's symptoms were serious enough that they both believed he might be having a heart attack. She said the GP provided "informal" help when they arrived.

The appeal went to an independent adjudicator at the London Tribunals. The council's position was straightforward — the vehicle was on the zigzags, the contravention occurred, and the PCN was properly issued.

The Arguments: Genuine Emergency vs. Insufficient Evidence

The driver's case rested on what lawyers call the "circumstances beyond the driver's control" defence. Under parking and traffic enforcement law, a driver can avoid liability if they can demonstrate, on the balance of probabilities, that they were genuinely prevented from complying with the restriction by something outside their control.

A sudden medical emergency — particularly a suspected heart attack — would, in principle, qualify. You cannot reasonably be expected to drive on when someone in your vehicle is in acute distress and may be dying.

The driver supported her appeal with a Home Blood Pressure Monitor Diary, which she said demonstrated her partner's ongoing cardiac issues. She also explained that the GP's involvement was informal, which is why she had no formal letter or medical record to produce.

The council, meanwhile, relied on its photographic evidence showing the vehicle clearly stopped on the zigzag markings. It did not need to argue about the medical situation — it simply needed to show the contravention occurred and let the driver prove her exemption.

The Decision: Appeal Refused

The adjudicator refused the appeal. Despite acknowledging the driver's account, the adjudicator was not satisfied that the medical emergency defence had been made out to the required standard.

The core problem was the evidence. The blood pressure diary had no dates on it — meaning it could not be linked to the specific day of the contravention. There was no letter from the GP, no medical record excerpt, no ambulance call-out record, and no hospital documentation. The adjudicator noted that the driver's explanation for this gap — that the GP's help was "informal" — sat uncomfortably with the seriousness of a suspected heart attack.

If someone genuinely believed they were having a heart attack, the adjudicator reasoned, you would expect some form of formal medical intervention and therefore some form of documentary trail.

The appeal was refused, and the PCN was upheld.

The Legal Reasoning: Why Evidence Is Everything

This case turns on a legal concept that sounds simple but trips up many appellants: the burden of proof.

In parking enforcement cases, the council's job is to prove the contravention happened. Once it does that — usually through CCTV footage or officer observations — the burden shifts. If the driver wants to claim an exemption, they must prove it. Not beyond reasonable doubt (that's the criminal standard), but on the balance of probabilities — meaning it is more likely than not to be true.

That sounds achievable. But "more likely than not" still requires actual evidence. A driver's word alone, however credible it may seem, is rarely sufficient — particularly when the council has clear photographic proof of the contravention.

The adjudicator also applied a subtle but important piece of reasoning: internal consistency. If the driver described the situation as a potential heart attack — a serious, life-threatening emergency — then the absence of any formal medical response becomes suspicious. Real cardiac emergencies tend to generate paperwork: GP notes, urgent referrals, 111 call logs, hospital visits. The informal nature of the GP's response undermined the claimed severity of the situation.

This is not the adjudicator saying the driver was lying. It is the adjudicator saying the evidence did not add up to the legal standard required.

The Highway Code is also clear on zigzag markings. Rule 191 states that you must not park on a crossing or in the area covered by the zigzag lines. These restrictions exist to protect pedestrians — drivers and parked vehicles on zigzags obstruct the sightlines of people trying to cross safely. The rules are strict precisely because the consequences of getting it wrong can be fatal.

Lessons for Drivers: What You Must Do If You Stop in an Emergency

This case is not about punishing a driver for doing the right thing. It is about the reality of how these appeals work — and how to protect yourself if you ever face a similar situation.

1. Document everything immediately

If you stop in a genuine emergency, create a paper trail as soon as possible. Call 111 or 999 if appropriate. Visit A&E. See the GP formally, not informally. The moment you have a PCN to contest, you need dated, verifiable records — not a diary with no dates.

2. Understand what "informal help" means to a tribunal

Describing medical assistance as "informal" raises questions rather than answering them. Tribunals deal in evidence, not impressions. If a GP saw your partner on the day, ask for a letter on headed paper confirming the date, the presenting symptoms, and the advice given. Most GPs will provide this.

3. Know the defence — and its limits

The "circumstances beyond your control" defence is real and it does work. But it requires you to meet a legal standard. Vague or undated supporting documents will not get you there. The stronger and more specific your evidence, the better your chances.

4. Act quickly after the incident

Memories fade and records become harder to obtain. If you know you stopped somewhere you shouldn't have — even for a very good reason — start gathering evidence the same day. Request GP notes, save call logs, photograph any visible symptoms if appropriate, and write a contemporaneous account of what happened and when.

5. Consider whether stopping was truly unavoidable

Zigzag areas are short. In many emergencies, it may be possible to pull forward slightly onto a safe section of road or into a side street. This is not always possible — but if there was a nearby alternative, the adjudicator may question why the zigzag was the only option.

The Key Takeaway

A genuine emergency can be a complete defence to a parking or stopping contravention — but only if you can prove it happened. Good intentions, credible accounts, and sympathetic circumstances are not enough on their own. The tribunal system is evidence-based, and the burden of proving an exemption rests firmly with the driver.

If you ever find yourself in a frightening roadside situation — medical or otherwise — your first priority is absolutely the welfare of the people involved. But the moment the immediate crisis is over, your second priority should be building the evidence trail that protects you legally. In the cold light of a tribunal hearing, it is that paper trail — not the story behind it — that will decide whether your appeal succeeds or fails.

This case is a reminder that the law is not heartless, but it is precise. Meet it on its own terms, and it can work in your favour. Arrive without evidence, and even the most compelling human story may not be enough.
