We have put together guidance for the organisers of events that may impact on the public highway. The guidance provides an introduction to the legislation and procedures for applying for a Temporary Traffic Regulation Order (TTRO).
There are separate processes for Street Party Events and Playing Out Events, where the temporary closure only affects one residential street.
Please continue to read the guidance below if your event does not fall into one of the three categories above.
Notify us of your event and apply for a Special Events TTRO
To notify us of your event and, where required, apply for a Special Events TTRO, please complete our online Highway Events application form.
Please read our guidance before completing the form.
Guidance on holding an event on the public highway
Local traffic authorities, in accordance with the Traffic Management Act 2004, have a duty to manage traffic on the authority’s public highway network. Managing the network assists with keeping traffic moving and reducing congestion.
Any event that has the potential for disruption must consult with the highway authority. Early engagement will assist the traffic authority to prevent problems on the network, helping organisers minimise the impact of their event on the highway.
This guidance gives event organisers:
- An awareness of relevant legislation
- Offers guidance to assist them to minimise their event's impact
- Introduces the procedures required to apply for Temporary Traffic Regulation Orders
The public highway encompasses all roads, bridleways, footways, footpaths and public rights of ways (PROW).
If you have any further questions or need clarification on any area of this guidance please email Highway.firstname.lastname@example.org.
2. Notifying the Traffic Authority
2.1 Any event that has the potential to cause disruption to the public highway should notify the traffic authority by completing a Highway Events application form.
2.2 Completion of the Highways Application Form allows:
- The Event Liaison Officer to coordinate details of your event with any known street work activity.
- Event organisers to apply for a Temporary Traffic Regulation Order (TTRO).
- Event organisers to apply for a permission. For example to use Stop/go boards or apply for permission to place temporary directional signage on the public highway.
- The Highways Authority to analysis its potential impact on the public highway.
- Offer appropriate advice to the event organisers.
2.3 Event organisers should take all reasonable practicable steps to identify land owners and environmental factors that may influence the planning for their events. Including identifying if their events venue/route is in the vicinity of any major utility infrastructure.
3. Temporary Traffic Regulation Orders (TTRO)
3.1 Temporary Traffic Regulation Orders (TTROs) are legal orders that allow for the implementation of temporary traffic management on the public highway. For events on the public highway orders are issued under section 16A of the Road Traffic Regulation Act as amended by the Road Traffic Regulation (Special Events) Act 1994.
3.2 Section 16A provides the power for the traffic authority to restrict or prohibit traffic (including bicycles, equestrian and pedestrians) on the public highway on a temporary basis to:
- Facilitating the holding of a relevant event
- Enabling members of the public to watch a relevant event
- Reduce the disruption of traffic likely caused by a relevant event
3.3 A relevant event is defined as any sporting, social event or entertainment that is held on a road.
3.4 The regulation is mostly commonly used to:
- Restrict or prohibit traffic on a section of public highway
- Restrict the speed of vehicles
- Prohibit or restrict the waiting, loading and unloading of vehicles
- Restrict parking provision
3.5 Limitations relating to a Section 16A TTRO
- Can only be used once on a length of road in one calendar year, except where prior permission has been obtained from the Secretary of State;
- Can only be in place for a maximum of three days, except where prior permission of the Secretary of State for the Department for Transport (DfT) or the traffic authority if the extension is requested while the order is in force;
- Can only be used for cycle races on the highway where the approval of Cambridgeshire Constabulary and other relevant authorities has been obtained in accordance with section 31(2) and (3) of the Road Traffic Act 1988 (RTA 1988) and the consultation requirements have been satisfied in accordance with section 195(2) RTA 1988.
- Traffic Regulation Order or other statutory provision which is currently in force in the road(s) to be closed will remain in force during the closure unless specified to the contrary on the Statutory Notice.

Event highway impact matrix
Scores shown in brackets
|Event size attendance||Highway closure(s)||Duration of highway closure*|
|Small 0 - 99 (0)||None (0)||0 - 5 hours (0)|
|Medium 100 - 499 (1)||One - three (1)||5 - 12 hours (1)|
|Large 500 - 4999 (2)||Three - ten (2)||12 - 14 hours (2)|
|Major 5000+ (3)||Ten+ (3)||48 hours+ (3)|
*Duration of road closure is calculated by taking the time the first road closes to the time the final road reopens i.e. If road A shuts at 09:00 and opens at 12:00 but road B shuts at 10:00 and reopens at 13:00 the duration would be 09:00 until 13:00 thus 4 hours of closure.
