The Kuala Lumpur–Kuala Selangor Expressway Kuala Lumpur–Kuala Selangor Expressway, KLS (formerly Ijok–Templer Park Highway, LATAR) or sometimes called LATAR Expressway, is an expressway in Selangor, Malaysia. It is part of the Kuala Lumpur Outer Ring Road. The 32 km (20 mi) expressway connects Ijok near Kuala Selangor to Templer's Park near Rawang and not Kuala Lumpur as its name suggests – consequently, motorists will need to travel another 20 km to Kuala Lumpur via Kuala Lumpur–Rawang Highway. Kuala Lumpur–Kuala Selangor Expressway is the fourth east–west-oriented expressway in the Klang Valley after the Federal Highway, the New Klang Valley Expressway (NKVE) and the Shah Alam Expressway.

Kuala Selangor is a town in northwestern Selangor, Malaysia. It is the largest town and administrative centre of the coterminous Kuala Selangor District.
