I think there has been no enforcement of existing laws, which would have helped in placing a check on the lawlessness. However, as the population of Riverside and San Bernardino Counties increases there will be more disputes over these issues between private property owners and OHV riders.
However, one of the problems is that much of the private property is not fenced or marked as private. If there were proper signs, then the private property owner could do a citizen arrest for trespass if the person were on their private property. I am concerned about laws that are subject to personal interpretation not clearly defined guidelines. These type of laws can be abused and arbitrarily enforced.
On public land managed by the BLM, the OHV riders have a right to ride on public land based on the Federal Land Management Act enacted by Congress. This would be unless the area had a special designation stating otherwise.
OHV activity leaves its mark on the land, is very noisy and dusty and offends many people and wildlife around them.
I think there should be designated areas for OHV activity, otherwise, if on public land or U. S. Forest land, the vehicles should stay on marked trails. It seems to me that the corporations who are profiting from the sale of these vehicles should also be a part of educating the purchasers, contributing to the cost of enforcement and providing places for these individuals to ride. This is a billion dollar industry that profits on the sales, however, does not deal with the repercussions caused by their purchasers.
