Re: Speed Limits and Gates on a Right of Way
unless the grant gives you exclusive use of the easement, you cannot stop him from using his own property. If the truck actually impedes your use of the easement, you can seek an injunction from the courts ordering him to not impede your use of the lane.
btw: if he places a locked gate and gives you the key, unless there is something in the grant demanding you abide by his demands to lock, or even close the gate, there is no obligation you lock or even close the gate. The one exception I can think of would be if he maintains animals that are contained by the use of the gate. He still couldn't make you lock the gate but if he lost animanls because you did not close the gate, you might be able to be held liable for the loss of the animal.
I am not an attorney and any advice is not to be construed as legal advice. You might even want to ignore my advice. Actually, there are plenty of real attorneys that you might want to ignore as well.
