Ask a room of van drivers what their licence allows and the answers split by age: the over-45s inherited rights the younger drivers never got, and the electrics have quietly redrawn the weight line for everyone. For fleets, the categories are not trivia - they are the boundary between a legal driver and an insurance-and-prosecution problem. Here is the map, using the government’s own category definitions.
Pass your car test and you hold category B - but WHEN you passed changes what B means.
Passed on or after 1 January 1997: vehicles with up to 8 passenger seats up to 3,500kg MAM for petrol, diesel and hybrid vehicles - and 4,250kg for zero-emission (electric or hydrogen) vehicles only. That 4.25-tonne electric allowance is the derogation fleets increasingly rely on: it puts the heavier electric vans - the e-Transit class - within reach of ordinary car-licence drivers. An electric van with extra equipment for disabled passengers can carry a further 750kg MAM, but only for that equipment. On towing: with a petrol, diesel, electric or hydrogen vehicle you can tow a trailer up to 3,500kg MAM, provided the combined MAM does not exceed 7,000kg.
Passed before 1 January 1997: the inherited - “grandfather” - rights. Usually a vehicle and trailer combination up to 8,250kg MAM, and a minibus with a trailer over 750kg. In practice this is where the C1 entitlement lives for older drivers.
Entitlements can carry restriction codes, and the definitive answer for any driver is on the licence itself - or the online check. Northern Ireland categories differ.
The 3.5-tonne assumption. “Van licence” is not a category - a post-1997 B licence stops at 3,500kg for anything burning fuel. A driver hired for the 7.5-tonner needs C1 on the licence, not just experience.
The electric bump, misapplied. The 4,250kg allowance applies to zero-emission vehicles only. The same driver in the diesel equivalent of that van is driving out of category.
Towing arithmetic. Trailer MAM and combined MAM are separate limits; a 3.5t van plus a 3.5t trailer exceeds the 7,000kg combination cap at full ratings even where each looks legal alone.
Ageing grandfather rights. Pre-1997 C1 is not immortal: it has to be renewed, and at 70 the renewal rules tighten - the rights lapse if the paperwork does.
Below B sits the powered two-wheeler ladder, and it matters to any operation using mopeds or scooters for delivery: AM covers 2- and 3-wheeled vehicles up to 45km/h (28mph), P covers up to 50km/h (31mph) and 50cc, Q covers the smallest - up to 50cc and no more than 25km/h, and is also the category trial e-scooters sit in. A1 steps up to light motorbikes up to 125cc and 11kW. The point for recruiters: these are distinct entitlements, and “has a driving licence” does not answer which one.
The categories are one page of law with an outsized blast radius: the wrong driver on the wrong weight class is uninsured, unlicensed, and a roadside stop away from a very bad day.
Category confusion costs most at the point of hire, so make it a scripted question rather than an assumption. “What vehicles can you drive?” gets an opinion; the online licence check gets the entitlements and any restriction codes in writing. For roles near a boundary - the 3.5-tonner fully laden, the 4.25t electric, the 7.5t box - the check should name the category, the vehicle’s MAM should be on file, and the two should be reconciled by a person, not by hope. The five minutes at recruitment is the cheap version of the roadside prohibition.
