Delhi Traffic Police has issued formal traffic advisories and diversion plans for central New Delhi and the Lutyens’ area ahead of the BRICS summit, regulating vehicular movement on key roads and establishing diversion points to manage VIP and VVIP movements.

Official guidance and contemporaneous reports identify more than 35 roads expected to be affected and around 22 diversion points set up to reroute traffic during VVIP movements. Targeted diversions have been used around motorcade rehearsals and specified dates to practise security procedures and convoy timings.

Authorities conducted or scheduled motorcade rehearsals — with at least one rehearsal referenced on Sept. 5 — that prompted targeted traffic advisories and temporary diversions on specified dates ahead of the summit.

Police and event authorities issued specific guidance for passengers bound for airports and principal railway stations, including New Delhi, Old Delhi/Old Delhi Railway Station and Hazrat Nizamuddin, recommending alternate routes and changes to pick-up and drop-off arrangements to reduce disruption.

Rail operations around New Delhi were reported to be affected during the summit window: multiple trains were cancelled, diverted or rescheduled between Sept. 11–13, according to railway-related advisories and news reports.

Delhi Metro services were not broadly suspended during the summit window. The Delhi Metro Rail Corporation announced that metro services would run and published an earlier start time on Sunday, Sept. 13, beginning at 06:00 to assist students and the public amid traffic restrictions.

Local residents and commuters reported significant congestion and expressed frustration about traffic disruptions and the planning around the event, with congested stretches and longer travel times noted across affected areas.

Authorities urged commuters to follow official advisories, use public transport such as the Metro where feasible, check real-time official updates and cautioned against sharing unverified social-media messages claiming blanket city-wide closures or a ‘bandh’.
