It was one of the major bus manufacturers in the Soviet Union and the largest-ever industrial company in the city of Lviv.

The Lviv Bus Plant LAZ was built in 1945 to produce ZIS buses for the USSR.

After the Soviet Union collapsed in 1991, LAZ suffered economic issues due to the loss of funding.

LAZ used a system called a "flexible assembly line", which gave the ability to produce a variety of different models simultaneously.

The DAZ factory plant had a large assembly hall, central compressed air system, welding and painting machinery and a testing center.

The central office for LAZ Holding was headquartered in Kyiv city center, Ukraine.
