A lowrider is a car or truck which has had its suspension system modified (with hydraulic suspension) so that it rides as low as possible. Lowriders often have user controlled height adjustable suspension. Lowriders are very often classic cars from the 1950s which rode low to begin with, although large numbers of 1940s and 1960s cars are also modified, and to a lesser degree newer vehicles. The word is also used to refer to those who drive or own such cars. A lowrider will traditionally have many factory offered accessories / options and often many after-market accessories added. As a result of the modifications, many lowriders are not street-legal vehicles.
