BiH Theory C study guide
BiH Theory C · Work through your exam, one topic at a time.
Theory C is the written knowledge test that candidates in Bosnia and Herzegovina sit before they are allowed to drive category C vehicles - lorries and other goods vehicles above 3.5 tonnes permissible maximum mass, usually with a trailer of up to 750 kg. It is aimed at people who already hold a lower category licence, or who are training for professional goods driving, and who need to show they understand the rules that apply to large, heavy vehicles rather than just to cars. The BiH Theory C study guide has 7 sections and about 2,751 words.
01Traffic Regulations and Road Signs in Bosnia and Herzegovina
Bosnia and Herzegovina's road traffic law is built on a clear hierarchy: a police officer's directions override traffic lights, traffic lights override signs, and signs override general rules. Many exam questions test exactly this ordering.

Licence categories define which vehicles you may legally drive, and exam questions often present a vehicle description and ask which category is required. The core European categories are AM (mopeds up to 45 km/h and 50 cc), A1, A2 and A (motorcycles by power and age), B (passenger cars up to 3,500 kg with up to eight seats besides the driver), BE (car with heavy trailer), C1 and C (lorries), CE (lorry with trailer), D1 and D (buses), and their trailer variants.

Vehicle dimensions and loads are governed by maximum permitted width, height, length and axle mass. Standard maxima in the region are around 2.55 m width for general vehicles, 4 m height, and axle loads near 10–11.5 tonnes depending on configuration; combination length is capped near 16.5–18.75 m.

Handling questions test whether you understand grip, weight transfer and stopping distance. Braking distance grows with the square of speed: doubling speed roughly quadruples braking distance, so 50 km/h needs about four times the distance of 25 km/h.

Accident prevention rests on anticipation: scan far ahead, keep an escape route, and assume other road users may err. The most common contributory factors are speed, alcohol, distraction and failure to yield.

At an accident, your first duty is to prevent a second collision. Switch on hazard lights, place a warning triangle at an appropriate distance (further on fast roads and in poor visibility), and get bystanders to safety behind the barrier.

A roadworthy vehicle is a legal requirement, and exam questions test which check catches which fault. Before driving, walk around: tyres for damage and pressure, lights and indicators, mirrors, plates, and any fluid leaks.
