Legal Question in Civil Rights Law in Virginia

Re: I drove into a black bar blocking a driveway at night

This is probably better answered by an Virginia attorney, but you should probably contact the landowner and ask them for the name of their insurer. Keep in mind, however, that they may also have a claim against you if you damaged their bar.

While they probably should have had a reflector on the bar, you are charged with operating your vehicle safely and maintaining a careful lookout, and thus your own negligence will be asserted against you as a defense.

Your best bet is to contact their insurer and see if you can reach an agreement to have them pay for the damages. If not, and the amount of damages are not over the limit for small claims court in Virginia, you might try that route.

Re: I drove into a black bar blocking a driveway at night

Apart from a contributory negligence defense (which completely bars claims in VA, as opposed to most other states), you were in fact trespassing on the neighbor's driveway. Since you had no right to be there, you have no claim.
