Reckless driving is taken very seriously in Virginia and categorized as a criminal offense, so adhering to speed limits is crucial. If there is no sign posted, 25 mph is permitted in residential areas, 55 mph is allowed on secondary roads (which are marked with a sign beginning with #600 or above). The highest speed limit on freeways is 70 mph, but it should also be adjusted to weather and road conditions. Search rental cars on KAYAK
