Not so much law here, in essence, as good sense and compliance with the 'highway code'.
Drivers of slow moving vehicles are required to pull over, as often as is reasonable and safe to do so, to enable other road users to pass and continue their duties unobstructed.
For information, there are two legal considerations at law here you should know;
1) The public Highway.
A public highway is defined as a way along which all persons have the right to pass and re-pass, except by obstructions that are either natural or legal.
2) Obstruction.
Obstruction of the public highway is an offence, defined by a Police Officer (in uniform), who given the circumstances may or may not decide that any obstruction to the public highway by persons or items deposited on the public highway is reasonable or not.
Obviously, in this particular case the Police are stating that they do not consider a slow moving vehicle, (in what may be a road where conditions enabling other vehicles to pass is difficult - you do not state this), is reasonable, and that the driver of the slow moving vehicle, whatever its type or configuration, must pull in/over often to avoid causing what the police consider to be an unreasonable onstruction of the legal right to pass and re-pass along the highway. Ultimately the Police have the legal right to make this decision and, if necessary, bring a prosecution for onstruction under the Highways Act 1980 (section 137).
For example,and in order to clarify the sometimes non-objective/reasonablness of such decisions, I have dealt with cases on the public highway where skips or other items have been placed directly in the path of pedestrians (on footways adjacent to carriageways forcing pedestrians into roads for example), blocking pedestrians passage on the footway to an extent that a pram or pushchair would be unable to pass, but a person could pass the 'obstruction'. When Polic have arrived to deal with the reported obstruction, they have stated there is none as persons are able to pass/re-pass the skip or other item(s), irrespective of wheather the item had been placed legally or illegally on the highway under the requirements of the above Act.
So, horses for courses I am affraid. If the Police say you are obstructing, you are. failure to obseve the reasonable request of
a police officer in uniform in such instances means you are 'wilfully obstructing' and the police may arrest you without warrant, which may lead to prosecution that carries hefty fines and a criminal record.
Hope this assists you in your endeavours.
