Can I put spikestrips in my driveway?

I live on a fairly busy wooded rural road and people are constantly using my driveway to turn around in. I understand why they do it, my driveway opening is very wide, but it still doesn't make it acceptable behavior, especially when this is happening multiple times a day. The driveway is far to wide for a gate, I don't want to permanently impede my own access by putting up a fence, boulders, etc etc. Can I put a spikestrip out? If I clearly post a sign stating something to the effect of "Private Driveway. Use at your own risk." or whatnot I would imagine that would take any liability off of me when you end up with four flat tires. I shouldn't have to worry about random vehicles flying around the edge of my driveway when I need to back out, the dogs, or god forbid the kids are out near the road. What do you all think? Any other suggestions? I'm all ears at this point.
