Cutting trees along side road

Have a stretch of road that has trees lying out across it, they are up a high stone ditch with not much holding them only roots at the back. The land is about 12 ft above the road so the trees are the same. Over the past couple of winters with high winds some have fallen but thankfully caused no damage. The land is quite wet so it doesn't suit to cut them during the winter. A tractor or loader or something similar would be needed in the field to pull them back in after being cut as they are all lying across the road. Can these trees be cut now when the land is dry as they are considered dangerous (in my eyes anyway and of other road users).
