F1 practice began in the early hours of Friday morning UK time, or late on Thursday night in the USA as the Las Vegas Grand Prix returned to the calendar for the first time in four decades.
Anticipation for the Nevada race is massive despite the drivers' and constructors' crowns both being long since locked up.
With all sorts of factors playing into the showdown on the strip, from concerns over temperatures to a new track drivers hold some apathy towards, it could end up one of the more dramatic races on the calendar.
It's sure to be quite the show but there is a little bit of confusion from some fans as to what is happening when - particularly with FP2 delayed after drain cover drama halted FP1.
