As for buses

How long will the TRP coupon be issued? It is worth noting that new cars are not required to undergo state technical inspection. If a light car is from 3 to 7 years, the TRP should be carried out every 2 years. If the car is more than 7 years old, it must pass the TRP every year, like trucks, trailers, training cars, as well as cars equipped with special signals. As for buses, taxis and vehicles transporting dangerous goods, for them the frequency of passage of the TRP is six months. Motorcycles are required to go through it once — immediately after acquisition.
