Goal Signposts are signposts that are only featured in Sonic the Hedgehog CD. It is seen nearly at the end of each round's first and second zones before the Goal Plate. Goal signposts have slightly similar shape of time warp plates, but have light blue sign with stating GOAL and yellow arrow pointing to the right direction.
While goal signposts may simply show the way to complete zone, these objects are actually set in order to prevent the player from initiating a Time Warp. The past or future sign symbols at left hand corner disappears automatically after the player runs past the Goal Signpost.
