The Caution Zone was a backyard roller coaster built by Will Pemble in Orinda, California.[1][2][3] Pemble was inspired to build, alone with his family members,[4] the roller coaster after riding the Kingda Ka in the Six Flags Great Adventure amusement park.[5]

The coaster was 180 feet long, fifteen feet high and cost US$3500 to construct.[1] It ran until 2015.
