The term "lay-by" is used in the UK and Ireland to describe a roadside parking or rest area for drivers. Equivalent terms in the United States are "turnout" or "pullout".

Lay-bys can vary in size, from a simple parking bay alongside the carriageway (sufficient for one or two cars only) to substantial areas that are separated from the carriageway by verges, which can accommodate dozens of vehicles.
Lay-bys are to be found on the side of most rural UK roads, except [[motorway]]s that are not on sections of [[smart motorway]]s (but for emergencies only) where the [[hard shoulder]] is missing. They are marked by a rectangular blue sign bearing a white letter P, and there should also be advance warning of lay-bys to give drivers time to slow down safely.<ref>Lay-by and advance warning of lay-by signage from the [http://www.drivingschoolireland.com/signs-information.html Irish highway code].</ref><ref>Advance signage of lay-bys instructions in [http://www.standardsforhighways.co.uk/dmrb/vol6/section3/td6907.pdf Standards for Highways], sections 4.8 and 4.9, from the [[Highways Agency]].</ref><!-- also distinguish between Highways Agency practice and legal requirements for local roads. -->
