Snakes are usually not thought of as being migratory, but they are creatures of habit. Different species will move farther distances than others, but all seek out habitats for similar activities. They are seeking areas for basking and shedding, foraging and digestion, mate searching, suitable nesting or birthing habitat, and overwintering. During these travels, snakes of many species will find roads that they will need to cross to reach necessary habitats. Unfortunately, roads play a major role in snake mortality each year, especially during the hotter months.
Smaller species such as common garter, smooth green, and red-bellied snakes may be difficult to spot on pavement. Larger species such as copperheads, black rat snakes, and rattlesnakes are easier to see and avoid hitting. Many will move out of the road when you approach, but some species will hold their ground. It is important to remember never to handle a venomous species; simply waiting for them to cross is an option. If in doubt, contact your county Environmental Conservation Officer for assistance.
