For the first time in a Formula 1 race, there will be three DRS zones on the race track, starting at the season-opening Australian Grand Prix on Sunday.
Tracks usually have either one or two designated areas where drivers within a second of a rival car can activate the DRS.
There should be plenty of scope for overtaking at the Melbourne based venue, as a third DRS zone has been added on the exit of the quick Turn 12.
If they are unable to take advantage of that temporary speed advantage, the drivers will soon enter another DRS zone after the final two corners of a circuit where it tends to be difficult to pass.
The first DRS zone comes into play after Turn 2 on the run down to Turn 3.
