Demonstrations and parades Sometimes, in special circumstances roads are closed to allow sporting events or parades to take place. When special events require the road to be closed off to general traffic a temporary road closure will be required which can only be granted with the written agreement of the police. Such closures require a Traffic Regulation Order. All costs involved for both the closure and diversion signing will have to be met by the event organiser. At least six weeks notice is required and for some events up to three months will be needed in order to organise them properly. Usually roads which are closed for sporting events can only be closed once a year without the consent of The Secretary of State. Demonstrations can not be dealt with by the Council and for these events the police must be contacted so that they can make the appropriate arrangements.
