The Miami Grand Prix Formula 1 venue will feature two shortened DRS zones for the 2023 race, despite complaints from the previous round in Baku from drivers.
The Miami International Autodrome will include three DRS zones for this weekend's event, which is the same number as last season.
However, the decision has been made to reduce the first and second DRS activation zones, which are the two longest zones of the 5.4-kilometre circuit.
The first zone is situated between Turns 9 and 11 - with Turn 10 being a flat-out kink - and the second zone is situated between Turns 16 and 17.
Both of these activation zones have been reduced by 75m, which will reduce the number of opportunities to overtake. The final DRS zone along the pit straight is unchanged.
The FIA have attempted to fine-tune the DRS zones at numerous venues this season. The Australian GP saw the return of four DRS zones, whilst the Azerbaijan GP had a shorter DRS zone on the main straight, which was likely a factor in the reduced number of overtakes in last week's event.
