First of all, make sure you are safe before trying to help a turtle across a busy roadway. Next, when you can help the turtle across in the direction it was headed. If you move it in the opposite direction it was headed, it will turn around and attempt to cross again. Some turtles may be aggressive even if you’re only trying to help. In these cases, try to use a shovel or a long handled tool to get them across and to keep your hands and feet safe from potential bites.
