However, if the player is in the past or the future, only one type of sign will appear which can transport them back to the present. In the present time, both past and future Time Warp signs appear and are available to use. When the player is transported to the past or future, the player's life icon is replaced with a P or F icon, representing past and future, respectively.

It will also disappear if the player runs past the Goal sign before the Bonus Plate. If the player fails to maintain enough speed for the required duration however, the symbol disappears and the player must try again with another Time Warp sign. If the playable character can then keep up their speed for a few seconds, the screen will fade out to white and the player will enter the Time Warp successfully. During this state, the player gains temporary invincibility against Badniks, allowing the playable character to destroy them without getting hurt even while running into them on foot but it will not protect them from other harmful obstacles. When they begin gaining speed, the playable character will have white stars trailing in their wake. Afterwards, the player must build enough momentum while the signpost's HUD symbol flashes. In gameplay, running past a Time Warp sign makes its signpost flip once while a voice states its particular name at the same time. In Sonic the Hedgehog CD, the Windows 95 version, and the 2011 remaster, Time Warp signs appear in Zones 1 and 2 of every Round, as unique features in the game.
