Understanding trailer rules with a B licence
Three numbers to remember: the towing vehicle's GVW, the trailer's GVW, and their combined weight (GCW). The required licence depends on the trailer GVW and the combined total.
B licence alone: what can you tow?
With a B licence you can tow a trailer with a GVW up to 750 kg — regardless of the total. Above 750 kg, the car + trailer combined must stay ≤ 3,500 kg. Beyond that you need a higher category.
B96: the "small" top-up
Who is it for?
B96 lets you tow a trailer over 750 kg when the combined weight is between 3,500 kg and 4,250 kg. Ideal for a small caravan, horse van or mid-size boat.
Length and price
Mandatory 7-hour training at a driving school, no practical exam (just an endorsement added to the licence). Price: €300–500. No medical exam.
BE: the full extension
When is it required?
Whenever the combined weight exceeds 3,500 kg OR the trailer alone exceeds 3,500 kg GVW (up to 7,500 kg). Essential for a heavy horse van, large caravan or heavy agricultural equipment.
Training and exam
Average 12–20 hours (practical only, no theory). 1-hour practical exam with off-road phase (manoeuvring, reversing with a trailer) and on-road driving. Price: €900–1,500. Medical exam required.
Watch out for common confusions
Twin-axle trailers
Many think a twin-axle trailer changes the rule — it does not. It is always the GVW on the registration document that counts, never the number of axles.
The real GVW is not the dealer figure
Always check the GVW on the trailer's registration document (field F.2), never the brochure. A caravan sold at "1,300 kg empty" may have a GVW of 1,800 kg, changing the required licence.
Which licence for which situation? Quick recap
Cycle trailer or small utility < 500 kg: B licence. 800 kg caravan towed by a small city car: B96 works. Motorhome towed by a pickup, pro trailer with tools, two-horse van, 6.5 m boat: BE.
