Turn 1: Turn 1 The first corner after the pit straight and the start of DRS zone 1; Vettel found no room to pass Hamilton into it at the 2018 start.
Turn 2: Turn 2 A 90-degree right-hander at the end of the long main straight and a heavy braking zone with big out-braking chances; a recurring first-lap flashpoint, where Rosberg flat-spotted his tyres out-braking Hamilton in 2014 and Bottas passed both Ferraris on his way to a maiden win in 2017.
Turn 3: Turn 3 A long, sweeping constant-radius left-hander around the Olympic Medals Plaza, compared to Istanbul's Turn 8 and a big test for tyres; Hamilton passed Vettel here in 2018.
Turn 4: Turn 4 A long constant-radius right-hander cited as the longest corner on the 2014 calendar; Hamilton completed his pass on Vettel into it in 2018.
Turn 5: Turn 5 A right-hander paired with Turn 4 as an overtaking chance; Lando Norris aquaplaned off here in the wet 2021 race, handing Hamilton his 100th win.
Turn 6: Turn 6 One of three corners around the Bolshoy Ice Dome.
Turn 7: Turn 7 Another of the Ice Dome corners; Hamilton overcommitted and ran wide here in 2018 qualifying, handing pole to Bottas.
Turn 8: Turn 8 The third of the Bolshoy Ice Dome corners.
Turn 9: Turn 9 The first of a series of tight corners; George Russell crashed here in 2019 after a wheel-nut issue.
Turn 10: Turn 10 One of the tight corners; Nicholas Latifi spun into a heavy practice crash here in 2020, causing a red flag.
Turn 11: Turn 11 The last of the tight-corner run before the track turns north.
Turn 12: Turn 12 A left-hand sweep and the entry to DRS zone 2; Norris regained the lead from Sainz through it in 2021.
Turn 13: Turn 13 A back-section right-hander flagged as an overtaking point and the most incident-prone corner; Sainz had a 46G practice crash here in 2015, and Mercedes ordered Bottas to let Hamilton through here in 2018.
Turn 14: Turn 14 Part of the closing sweep skirting the Olympic Park above the Olympic Village.
Turn 15: Turn 15 Part of the closing sweep past the skating and curling centres; several drivers spun or ran wide between Turns 15 and 16 in 2016 practice.
Turn 16: Turn 16 The closing sweep where Vettel retired his Ferrari in the 2019 race.
Turn 17: Turn 17 The first of the two 90-degree right turns that complete the lap toward the pit paddock.
Turn 18: Turn 18 The second of the closing 90-degree right turns, feeding onto the pit straight; Bottas made an error at the final corner on a provisional pole lap in 2014.
