Born in Bogotá, Huertas began his career in Formula BMW UK in 2007 with Räikkönen Robertson Racing where he finished 13th.

He returned to British F3 and Räikkönen Robertson in 2010 but dropped to 10th in points, but recorded four podium finishes.

Huertas switched teams to Carlin in 2013 and improved to 14th in points and captured his first win at Ciudad del Motor de Aragón.

He won his first race in a very eventful 2014 Grand Prix of Houston by running more laps in one stint than anybody else.

Four days later the car was found to have an illegally large fuel tank as well as a rear wing infringement.
