After a difficult 2009 season, Hamilton set out with a new challenge for the title. He finished third in Bahrain. In Australia, Hamilton failed to make the top ten in qualifying. He starting the race from eleventh place on the grid, and ending the race in sixth place. He had a late-race collision with Mark Webber. At Malaysia, McLaren misjudged the weather during qualifying, and let Hamilton go out on the wrong tyres for the wet conditions. He started 20th on the grid for the race, but came through with a sixth place finish. Hamilton was given a warning during the race. He weaved four times trying to break the aerodynamic tow of Vitaly Petrov. Hamilton was not trying to block him. After the race the rules were clarified. A driver may weave only once, even to break a tow.
