NORTH COURTLAND, Ala. (AP) — Students at a north Alabama high school are campaigning to change traffic laws after a teenager died in a wreck at what they say is a dangerous intersection. Students at R.A. Hubbard High School in North Courtland want to lower the speed limit at an intersection where Hatton High School junior Caitlyn Martin was killed in April. Hubbard students are writing letters to legislators to lower the 65 mph speed limit at the intersection of Alabama 157 and Highway 101. Math teacher Karen Posey tells The Decatur Daily that traffic goes too fast at the intersection. Hubbard senior Alex Gholston says a red light could also help. An 18-wheeler struck a car at the intersection on April 30, killing Martin and critically injuring her younger sister.
