It is an important rest stop for heavy goods vehicles (HGVs), because the driver's resting periods are strictly monitored with a digital tachograph. Most of the trucks on Finnish national road 4 stop or stay overnight in Pihtipudas, whilst some of the drivers living in the area also use the rest area to store their vehicles.
