Sign Crushes Motorist is a musical project by Irish musician Liam McCay (born 28 February 2005). Originally from County Donegal, he is best known for releasing music under this pseudonym, though he has also released music under several others, including Birth Day, Take Care and Dead Calm.

Named after a Duster song of the same name, McCay gained wider recognition in 2023, when several tracks took off online. In December 2023, Eli Enis of Stereogum described the project as “one of the most popular slowcore bands on the internet”.

In October 2025, BBC News reported that McCay had developed more than 14 musical aliases, with Sign Crushes Motorist alone surpassing 2.2 million monthly listeners.
