. Double yellows
Parking to load or unload on double yellow lines is only permitted if the load is of sufficient volume, weight or difficulty – collecting a newspaper from a shop doesn’t count. Photo: Shutterstock

. Emergency vehicles
The Highway Code says that you can’t park anywhere that may restrict access for emergency services, such as leaving a residential road too narrow for a fire engine. Photo: Shutterstock

9. Reserve a space
Putting out cones, bins or other obstacles to reserve a parking space is not permitted, as it could be interpreted as causing an obstruction resulting in a fine.

10. Engines off
All engines should be switched off if leaving a vehicle for some time on a public road – the law states you have to be ‘in control’ of your vehicle so don’t leave it unattended and running.

11. Clean car
Allowing a parked car to build up dirt could leave its registered owner open to prosecution, as having an unreadable number plate is illegal.
