The Progression Gates

The upper categories aren't just separate — they're sequenced. To move up to Category C or D you must typically be at least 24 years old with a minimum of 4 years' experience on a Class B licence (C1 opens earlier, at 22).

The logic connects straight to Module 4 and the hierarchy of responsibility (Lesson 1.5): the vehicles in C and D carry the most kinetic energy, the most passengers, and the harshest consequences for error — so the licence system prices experience into access. A lorry is not a big car; the licensing structure is the law agreeing with the physics.

Key takeaways

Upper categories are sequenced, not just separate — C/D require age and experience minimums built on a B licence
The gate is the law agreeing with the physics: more mass, more passengers, more consequence, so experience is priced into access

Quick check

Why does moving up to Category C or D require age and experience minimums that Category B doesn't?

A) Because C/D vehicles carry the most mass, passengers, and consequence for error — the licence prices experience into harm potential

B) Because larger vehicles are more expensive to insure

C) Because the test is administratively harder to schedule

D) Because only professional drivers may hold more than one category
