BiH Theory C

C1 covers goods vehicles between 3.5 and 7.5 tonnes; C covers vehicles above 3.5 tonnes, typically up to 12 tonnes or more depending on national rules, and allows a trailer up to 750 kg. The theory content overlaps heavily, but C questions assume heavier vehicles and stricter load and driving-time rules.

The number of questions, the time limit and the pass mark are set administratively and are not fixed for all candidates or all testing centres. Check the current figure with the competent cantonal or entity authority, or ask your driving school, which works with the latest version of the test.

The sign and right-of-way material is similar, so a recent category B pass helps. The extra difficulty is lorry-specific: masses and axle loads, load distribution and securing, braking on descents, blind spots, driving and rest times, and vehicle checks. Candidates who only revise car material usually find these areas the hardest.

In most cases yes, and it is the sensible order. Passing theory first means your practical hours are spent learning to drive the lorry rather than learning the rules. Your driving school will tell you the exact sequence and what documents you need to register for the exam.

Retake rules, waiting periods and any additional fees are set by the competent authority, not by the testing centre, so they can differ between cantons and entities. Ask before you book so you know the cost of a failed attempt. Use the waiting time to review your wrong answers rather than simply re-sitting.

Start with road signs, markings and right-of-way, because they appear throughout the paper and are quick to master. Then move to vehicle categories, dimensions and loads, followed by driving technique and safety. Leave first aid, maintenance and eco-driving for last - they are smaller shares but contain easy marks that many candidates lose.

Because they memorise limits without understanding them. Learn how permissible maximum mass, axle load and payload relate, how load placement changes axle loading and stability, and why securing matters. Questions often describe a situation rather than asking for a number, so reasoning beats rote recall.

Take them timed and without notes, then spend more time reviewing errors than taking new tests. For each wrong answer, find the rule in the official handbook and write one line explaining why the correct option is right. Repeat the same test after a few days; if you repeat the same mistakes, that topic needs proper study.

Yes. It is a scored section, and lorry drivers are often first on the scene of serious incidents. Focus on the universal basics: securing the scene and calling for help, checking responsiveness and breathing, recovery position, stopping severe bleeding, and what not to do with a suspected spinal injury.
