About the Belarus GAI Theory C Exam

The Belarus Category C driving theory examination is the official computerized knowledge test administered by the State Automobile Inspectorate (ГАИ МВД Республики Беларусь) for commercial truck and heavy goods vehicle (HGV) driver licensing. Category C authorizes driving motor vehicles (other than Category D) with a permissible maximum mass exceeding 3,500 kg. Governed by Presidential Decree No. 551 of 28 November 2005 (most recently amended by Decree No. 295 of 4 August 2025, in force from 1 September 2025) and the national traffic rules it approves (ПДД Республики Беларусь), the examination assesses proficiency in heavy vehicle traffic rules, lane restrictions on multi-lane highways, truck speed limits, freight transport and load securing, vehicle dimension and axle load standards, pneumatic air brake operation and maintenance, required safety equipment (including at least two wheel chocks), first aid, and administrative liability. This practice bank provides an English-language study adaptation.

Belarus GAI Theory C Study Tips from Top Performers

1Memorize the 10-question / 15-minute test format and the strict 9/10 passing score.

2Know truck-specific speed limits: 60 km/h urban, 70 km/h outside built-up areas on ordinary roads, and 100 km/h on motorways and roads for cars since the September 2025 amendment.

3Review the multi-lane road rule: trucks > 3.5 t must never travel in the 3rd or further left lanes except to make a left turn or U-turn.

4Remember heavy truck technical specifications: minimum tyre tread depth is 1.0 mm, maximum steering play is 25 degrees, and at least 2 wheel chocks must be carried.

5Study pneumatic brake systems: operating pressure is 6.5–8.0 bar, the low-pressure warning activates below 0.45–0.5 MPa, and air tanks must be drained regularly to prevent moisture accumulation.

6Review cargo transport rules: maximum vehicle height is 4.0 m, maximum width is 2.55 m (2.60 m for isothermal bodies), and cargo protruding more than 1 m front/rear or 0.4 m laterally must be marked with large-dimension warning signs.
