I do also wonder about prosecutions for overloading if you exceed the MTPLM but the caravan could be uprated to that figure or more without any alteration. On that basis there must be an argument that the actual maximum was not exceeded and the caravan was not overweight but simply exceeded an artificial figure used by the caravan builder to sell more caravans.
Hello Ray,
The second point you made in your last post has made me reexamine the issue of MTPLM vs MAM vs Axle Limits for trailers. The implications and consequences are different depending on what approach you make to subject.
Legally the assessment of over loading (as different to other load related offences) is determined by measuring the load in question and comparing it to the stipulated limits. The only grey bit is the calibration of the measurement device and the tolerance required to to remove all uncertainty. Once any measurement error is removed the matter is very black and white.
But your point is what is the limit? Regardless of what can be done by the manufacturer to upgrade the MTPLM, unless that process has been undertaken, the limit is what the caravan is registered as having at the date of the alleged offence.
It long been a practice to have goods vehicles down plated where they are transporting bulky low density products. To get a vehicle suitable for the volume means purchasing a vehicle of the next weight rating and then getting down plated. Mechanically its quite capable of carrying more than its plated weight, but if it is stopped and found to be loaded above its plate, the offence is overloading based on its plated weight not its mechanical capability.
The offence of overloading is different to having a dangerous load. A dangerous load is more difficult for the crown to prove, and whilst overloading could result in a dangerous load, its important to understand that sometimes a dangerous load does not have to mean a vehicle is over loaded.
For drivers with only CAT B licences there are other pitfalls. Consider a Cat B driver purchasing a secondhand caravan, where the basic specification states the MTPLM which is just below their tow vehicles ULW, but then the previous owner of the caravan had the MTPLM increased which takes it over the tow vehicles ULW, the new owners licence would be invalid.
How insurance companies accept liability or otherwise will depend on the individual case. For example if there as a provable case of deliberate overloading, I suspect the insurance company would seek redress from the policy holder, If the incident was accidental, then the insure may take a more lenient view.
