Know when to help the across and when to help them behind
WHEN THEY MIGRATE AND WHEN THEY NEST
Turtles move between habitats in their territory and should not be restricted to one site from any fencing or loss of habitat- as a turtle often needs many wetlands and habitat areas to thrive and survive.
If they were on the road travelling across (as opposed to nesting) and if it is safe to do so, move them in the direction they are heading.
During late May and the month of June in Eastern North America, it is nesting season and during this time mother turtles may be on roadsides; they may make large U-turns back to the wetlands behind them as opposed to crossing roads, therefore, watch at this time to make sure they wish to cross the road before helping.
SAFETY FIRST
If you see a turtle on the road you may have a strong desire to help it across or off the road. Turtle Guardians and The Land Between cautions that this may create a safety hazard to yourself or others, so please be aware of oncoming traffic and other factors. Also note that turtles, especially snapping turtles attempt to protect themselves and may snap. Too turtles may pee. Turtles spines are fused to their shells and are part of their tales; so that handling turtles by their tales may injure their ability to move and survive.
Health Considerations
Although it is rare in the wild (and much more common in captivity) turtles can contract and carry salmonella. Furthermore, and more recently turtles have contracted diseases that can harm other turtles such as Rana Virus and Turtle Herpes. Therefore just in case, when you touch a turtle to help it cross a road, it is always important to wash your hands!
