I had not parked when I received the PCN, I remained in the vehicle with the engine running. Am I still liable to pay?

Decision Date: 2023-10-12

Waiting in the vehicle and parking are the same thing.

See Key Case: Review decision of Schwarz v Camden (2001) PATAS 2110000692, which considers the definition of ‘parking’ with reference to the Road Traffic Regulations Act 1984 and Strong v Dawtry (1961)1 WLR 841.

I/ my passenger felt unwell and I pulled over to get some air, to use a lavatory, to buy some water, etc. at the time the PCN was issued, am I still liable to pay?

Decision Date: 2023-10-12

Restrictions are not lifted in such circumstances – motorists are expected to find an appropriate parking space. A medical emergency is, however, a separate issue that, with supporting evidence, could amount to a valid ground of appeal.

Should I have received a PCN if there were problems with the signs and lines where I parked?

Decision Date: 2023-10-12

Lines and signs serve to advise the motorist of a restriction and must not mislead. Trifling omissions, however, do not render a sign or line unenforceable.

So long as the sign or marking does not mislead and remains substantially compliant with the requirements of the regulations, the restriction is enforceable.

See Key Case: R (on the application of Herron and Parking Appeals Limited) v The Parking Adjudicator and others (2010) and Letts v London Borough of Lambeth PATAS 1980151656 (1980).

My parking space was taken by a visitor / access to my garage was blocked, is the PCN still enforceable?

Decision Date: 2023-10-12

When motorists cannot access their usual, preferred or expected parking spot, it does not entitle them to park elsewhere without complying with the applicable restrictions. This is the case even if the vehicle blocking their access or taking the space has done so unlawfully.

Should I have received a PCN if other vehicles were parked and I was told by a local that parking was permitted?

Decision Date: 2023-10-12

Motorists should always check signs and road markings for themselves.
That other vehicles appear to be parked at a location is not a reason for following suit – those motorists may have permits, or may be engaged in activities that cause an exemption to the parking restrictions to arise.
