Yes you can, just by parking your vehicle at the end of the driveway where the strangers are unable to pull their vehicle onto your driveway.

An encroachment is an infringement on someone else's rights or intrusion on another person's property. It is most often used when describing real property such as the corner of an neighbor's garage that extends over the property line or a driveway that gradually grew over the property line and is now partly on your neighbor's land. Encroachments are often caused by surveyor error in placing the pins marking the boundaries in a subdivision and the party who built their swimming pool partly on their neighbor's land was not at fault.
Was there any language recited in your deed that set forth a common driveway on the property line? If not, you could speak to a real estate attorney to explore other options. You may have an easement by operation of law, since you have used it for such a long time.
