CATEGORY B LICENCE FIRST OBTAINED ON OR AFTER 1 JANUARY 1997 MAY DRIVE:
a. Towed Outfits driver restricted to a combined MAM of 3,500kg and the trailer MAM must not exceed the unladen weight of the towing vehicle (85% ratio remains strongly recommended). If this MAM is to be exceeded an E Test pass is required. A list of B+E test driving instructors can be found in the Practical Advice section of The Caravan Club Website. The Driving Instructors’ Association also has a list of qualified driving instructors that can tutor those wishing to take the B+E driving test - visit the Driving Standards Website on
www.dsa.gov.uk, or telephone 0845 345 5151.
Dont confuse kerb weight with MAM(maximum authorised mass) If your car fully laden is sat 2200kgs you would be limited to a caravan with a maximum weight of 1300kgs = 3500kgs, provided this doesn't exceed the manufacturers maximum towing capacity which with Renaults can be very low compared to the vehicle. The other figure to check is your cars maximum train weight which again some manufacturers set low.
PS it is not always very clear and does take a bit of time, best to record all your weights from car and caravan and make sure no maximum is exceeded as some may be construction and use offences and some licensing offences, get any wrong and have an accident and no insurance will cover you.
Hope this helps
