[Who knew the 10th amendment to the US Constitution would create the state-by-state patchwork quilt of driving laws we've got? Well, the founders did — despite their lack of cars. Fear not, interstate drivers, we here at Jalopnik have sorted through the red tape to bring you detailed guides to driving rules; everything from teenage driving, cell phone use, open containers, dehorsing and lemon laws. These are the Rules of the Road.] Previously, we provided a list of the maximum speed limit laws by state. This let you know where it would be possible to drive legally more than 70 mph on a two-lane road (thank you Texas Legislature). This week, we focus on actual enforcement by looking at how often states ticket their speeding citizens and how much those tickets may cost.
