Drivers beware: When crossing state lines, you may unknowingly face some pretty strict traffic laws.

Driving too fast in Virginia has been known to land people in jail. Louisiana is implementing new fines for touching cell phones while driving. And in Utah, judges are now allowed to ban you from buying alcohol if you get caught driving while extremely drunk.

Peter Savolainen, the chair of the Department of Civil and Environmental Engineering at Michigan State University, said there isn’t national data about whether states with stricter rules have safer drivers. But more enforcement is probably good for the roads overall, he said.

“If we had states that had more rigorous enforcement, I’m confident we’d have more effectiveness there and lower (speeding) or lower alcohol consumption or lower cell phone use, or whatever the case may be,” he said.
