Traffic Control for Special Events and Filming in California

Parades, fun runs, farmers markets, street fairs, block parties, festivals and film shoots all have one thing in common: they temporarily take over streets that people normally drive, bike and walk on. That makes them work zones in the eyes of the traffic control rules, even though nobody is digging. This page explains how event and filming traffic control works in California, who approves it, and what to plan for, with examples from Southern California agencies.

Events are covered by the same traffic control manual

The California MUTCD treats a planned special event as a type of temporary traffic control zone. Section 6B.02 notes that events often require altered traffic patterns to handle increased traffic, and that the zone can be as small as closing a street for a festival or as large as a whole municipality for major events. Its duration matches the duration of the event.

The manual’s guidance (Section 6B.01) is clear: for any planned special event that will affect traffic on a street or highway, a TTC plan should be developed in conjunction with, and approved by, the agency or agencies with jurisdiction over the affected roads. It also notes that well-designed event plans usually combine treatments from several of the manual’s typical applications, because no single standard drawing fits a race route or a street fair.

Who approves an event or filming closure

City and county streets

Most events happen on local streets, so the city or county is the main approving agency. California Vehicle Code Section 21101(e) allows local authorities to temporarily close a portion of a street for celebrations, parades, local special events and other purposes when they find it necessary for public safety. Cities usually run this through a special event permit office, public works, the police department, or a combination. In unincorporated Orange County, for example, OC Public Works encroachment permits cover filming and photography as well as road or lane closures.

State highways

Many main streets are also State routes. On a State highway, an event needs a Caltrans encroachment permit. The Caltrans Encroachment Permits Manual (Section 514) defines special events as marathons, bike-a-thons, walk-a-thons, parades or other local celebrations held on a State highway in a way that directly affects traffic. Among its points:

  • Permittees are responsible for all traffic control for the event and must coordinate with other affected jurisdictions.
  • By statute (Streets and Highways Code 682.5), no more than four permits may be issued for the same activity at the same location in a calendar year.
  • Before issuing a permit, districts consider questions such as whether there is a staging area and whether it could cause traffic problems, whether local law enforcement is cooperating, and whether emergency services are arranged for participants.
  • Caltrans provides a special event application checklist (form TR-0410).

Filming

For commercial filming on State highways, the Caltrans manual says all applications must be submitted through the California Film Commission. For local streets, film permits go through the local film office. In Los Angeles, FilmLA coordinates permits for the City of Los Angeles, unincorporated Los Angeles County and a number of other cities.

What FilmLA says about street closures in Los Angeles

FilmLA’s guidance on closing streets for filming (published May 2024) is a useful example of how detailed local requirements get:

  • Productions need closure plans from a licensed barricade or traffic control company, and closures must follow the WATCH (Work Area Traffic Control Handbook) guidelines.
  • In the City of Los Angeles, closures require one LAPD officer per travel direction closed, and at least two officers for full street closures.
  • In unincorporated LA County, the County’s roads department requires CHP officers or Sheriff’s deputies to close roads.
  • Intermittent traffic control (briefly holding traffic for a take) is restricted during rush hours (7 to 9 a.m. and 3 to 7 p.m.) on major streets such as Fairfax Avenue, Venice, Sunset and Hollywood boulevards.
  • Larger requests may need approval from Council offices or other stakeholders, and some jurisdictions need extra lead time.

Requirements in other cities differ, so confirm with the film office for each location.

Planning an event traffic control plan

An event plan usually covers more than a work zone plan does. Common elements:

  • Closure limits and times, including setup and teardown, which often take longer than the event itself.
  • Hard closures with ROAD CLOSED signs on Type 3 barricades where the street is closed to all traffic, and Local Traffic Only signing where residents still need access up to a point.
  • Detours signed over their entire length, checked for truck and bus restrictions.
  • Pedestrian routes. Events generate crowds. The CA MUTCD requires adequate pedestrian access and walkways when pedestrians are affected, and says routes should be accessible to people with disabilities.
  • Crossing points where the public can cross a race course or parade route, and who controls them.
  • Emergency access routes through or around the closure for fire, police and ambulances.
  • Transit, parking and rideshare, including relocated bus stops and drop-off zones.
  • Law enforcement roles, where the agency requires officers for closures or intersection control.
  • Advance notice to residents and businesses, and portable changeable message signs ahead of the event where useful.

Moving events: races and parades

Runs, rides and parades move through the course, so closures may open and close in sequence. Plans typically show staged openings behind the last participant, and the location of each barricade and staffed crossing along the route.

Film shoots

Filming often uses intermittent traffic control, holding traffic for a few minutes during a take, rather than a full closure. Where lanes or parking are taken for equipment and base camp, the setup is similar to a short-term lane closure.

Frequently asked questions

Do I need a traffic control plan for a block party?

Usually, if the street is closed. The city will tell you what it needs; small residential closures sometimes use a standard layout, while larger events require a site-specific plan.

How far in advance should I plan event traffic control?

Start as early as possible, especially for State highways, multi-jurisdiction routes, or anything needing police staffing. Lead times are set by each agency.

Who provides the barricades and signs?

The event organizer or production is normally responsible for traffic control, often through a traffic control company. The Caltrans manual, for example, makes the permittee responsible for all traffic control for events on State highways.

Can a film crew stop traffic without police?

It depends on the jurisdiction. In the City of Los Angeles, FilmLA says LAPD officers are required for street closures. Check the local film office’s rules for your location.
