Why C directly and not C1
C1 (truck up to 7,500 kg) has a lower minimum age (18) and slightly shorter training, but limits the vehicles you can drive. Most trucks in the professional transport market are above 7,500 kg — C1 would lock you out of long-haul positions, heavy urban delivery and tractor-unit driving (with C+E).
In practice, getting C1 and then stepping up to C usually costs more (two trainings, two exams, two fees) than going straight to C. Exception: if you’re 18–20 and need to start working NOW with vehicles up to 7,500 kg, C1 qualifies you sooner. Detailed comparison in C1 vs C: which suits you.
The C theory exam: two tests
Unlike the B (single theory test), the C licence requires passing TWO tests in the same sitting. The common one (30 questions / 3 errors / 30 minutes) reviews general syllabus — useful if years have passed since your B and you need a refresher. The specific one (20 questions / 3 errors / 30 minutes) is the C core: truck mechanics, digital tachograph and regulation (EU Regulation 561/2006 on driving and rest times), dangerous-goods rules (ADR introduction), maximum authorised mass, tare, payload and legal dimensions.
Typical study plan: 4–6 weeks. First 1–2 weeks, review the common (especially if years have passed since the B). Weeks 3–5, specific block — tachograph generates the most errors, alongside dangerous goods. Week 6, combined real-time simulations of both tests. Aim for 5 consecutive simulations with 0–2 errors in each block before booking.
The practical: the truck changes the rules
Driving a rigid truck is nothing like driving a passenger car. Three critical differences the examiner evaluates: 1) mass changes all planning — braking requires anticipating 4–5 seconds more, corners are taken slower to avoid rollover; 2) blind spots are huge and demand constant use of convex mirrors; 3) vehicle height introduces real restrictions — low bridges, clearances, underground parking forbidden.
Closed-circuit manoeuvres are tested first: reversing in straight and curve (the C's stumbling block, where most fail), perpendicular and parallel parking, controlled braking from 30 km/h, hill-start with simulated mass. Then the on-road test lasts 45–60 minutes. Common fail causes: not respecting amplified safety distances, poor mirror reading on lane changes, getting dragged by the pace of passenger cars.
CAP: mandatory training to work
The CAP (Certificate of Professional Aptitude) is what enables you to drive professionally — without it, the C licence only lets you drive company trucks for internal use, no paid public transport. Training is in-person at certified centres: ordinary initial CAP is 280 hours with access from age 21; accelerated initial CAP is 140 hours and allows starting work (restricted to national territory at first) from age 18. Every 5 years renewal is required with a 35-hour course (continuous CAP) or the licence loses professional validity.
CAP cost: €1,000–€1,800 depending on region and format. SEPE may subsidise part for active workers. Many transport companies cover the CAP in exchange for a permanence commitment (12–24 months). If you'll get the C without intent to work professionally (only own company vehicle or restricted use), you can skip the CAP — but you lose 80 % of the licence's labour value.
Real cost of the C licence
C licence only: €1,500–€3,000. With CAP: €2,500–€4,500. It is the most expensive licence in the system due to practical training with a real truck (fuel + vehicle depreciation + professional instructor) and the stricter medical-psychotechnical exam.

Frequently asked questions about the C licence
- What is the minimum age for the C truck licence?
- The minimum age for the Spanish C licence is 21 with the freight CAP. Without CAP only restricted driving is allowed (company-owned vehicles, no paid professional transport). To access the C licence you must already hold a valid B (car) licence — direct access is not possible. If the training includes the accelerated CAP, you can access restricted national-territory tasks from age 18.
- What does the C licence authorise, and how does it differ from C1?
- The C licence authorises trucks with a maximum authorised mass (MAM) over 3,500 kg with no upper limit — including heavy rigid trucks of 18, 26 tonnes or more, and unloaded buses. It also permits a light trailer (up to 750 kg). C1 is a limited version: trucks between 3,500 kg and 7,500 kg, with lighter training and minimum age 18. Most professional drivers go straight to C because C1 wouldn't cover standard freight transport vehicles.
- How many questions does the C theory exam have?
- The C theory exam has TWO separate tests. Common test: 30 questions, 30 minutes, max 3 errors — shares syllabus with the B but is updated if more than 10 years have passed since your B licence. Specific test: 20 questions, 30 minutes, max 3 errors — freight-transport-specific blocks, truck mechanics, tachograph, driving and rest periods, weight and dimension regulations, introduction to dangerous goods. Both tests must be passed in the same sitting.
- What is the CAP and why do I need it?
- The CAP (Certificate of Professional Aptitude) is the mandatory training to drive trucks and buses professionally in public transport. Without CAP you cannot work as a hauler. Two routes: ordinary initial CAP (280 hours, access from age 21) or accelerated initial CAP (140 hours, restricted access from age 18). After obtaining it, renewal is required every 5 years via a 35-hour course (continuous CAP). The CAP exam is independent of the C licence — separate paperwork but professionally connected.
- How much does the C licence cost in Spain?
- C licence only (no CAP): €1,500–€3,000 on average. Includes the DGT fee (€94.05), medical-psychotechnical exam stricter than the B's (€60–€100), specialised driving-school enrolment (€200–€400) and practical lessons with a real truck (€30–€50 per hour, minimum 8–12 hours). CAP adds another €1,000–€1,800 for the 140- or 280-hour training. Total cost with CAP typically runs €2,500–€4,500 — many schools offer combined packages with discounts. SEPE (Spanish public employment service) can subsidise part of the CAP for active workers.
- What is the C practical exam like?
- The C practical has two tests. First, closed-circuit manoeuvres: reversing in a straight line and in a curve (truck manoeuvres are the key difference from the B), perpendicular and parallel parking, controlled braking and hill-start with the mass of a loaded truck. Second, on-road test for 45–60 minutes with the examiner on board the truck. Specifically evaluated: managing the truck's amplified blind spots, anticipation, correct mirror use and planning trajectories through tight intersections.
- Which licence should I get first: C, C1 or C+E?
- For standard professional transport, going straight to C is the most cost-effective in the medium term. C1 (up to 7,500 kg) only makes sense if you'll drive large vans or light trucks (Iveco Daily, small MAN TGL, etc.) without needing higher capacities. C+E (with heavy trailer, semi-trailer and trailer) requires holding the C first and is obtained afterwards — authorises articulated trucks typical of long-haul road transport. If your goal is professional long-distance trucking, the typical path is: B → C → C+E + freight CAP.
- Do I need a different medical exam for the C licence?
- Yes. The medical-psychotechnical exam for professional licences (C, D and variants) is stricter than for the B. It includes visual acuity with stricter requirements (10/10 in each eye or equivalent with correction), audiometry, cardiovascular testing, neurological assessment and extended psychotechnical testing. Periodic renewal is also more frequent: every 5 years up to age 65, then every 3 years (the B renews every 10 years up to 65). The centre must be DGT-authorised and the exam takes longer than the B's.
