Most curbing on Florida roads is straight and tall, so that once turtles enter the roadway the curb becomes a wall that turtles cannot climb to get back out of the road. They get stuck, basically waiting for a car to hit them or for some person to stop their car in traffic and dart out to carry the turtle to safety. It is a completely preventable situation if the state would just require different curbing (S or D shaped) on roads, particularly through wetlands, wooded areas, or beside lakes, or would put fencing along such roads to keep the turtles out. Minnesota Department of Natural Resources has published a guide for making roads more turtle-friendly, and this petition is to urge the State of Florida - a wetlands state - to implement turtle-friendly designs into its roadway projects.(http://files.dnr.state.mn.us/eco/nongame/turtle_flyer.pdf)
Here's a Youtube video about Minnesota's efforts to make roads more turtle (and other wildlife) friendly: http://www.youtube.com/watch?v=gVjCyjhe1zw. It's so simple!
