Katie Couric's Notebook: Aggressive Drivers

You're driving along the highway and suddenly another car's right on your tail. It speeds up, cuts in front, and then zooms on to intimidate someone else.

We've all been the victims of aggressive drivers. Maybe you'll even admit to being one on occasion. If so, beware.

Police in several states are conducting ticket blitzes this summer. Get caught in Maryland, for example, and the fine could be $500. That will help cities and states close huge budget gaps, but will it make the roads safer?

Maybe not. Statistics show stepped-up enforcement doesn't always work. When the National Highway Traffic Safety Administration studied two programs, it found crashes caused by aggressive driving dropped in Tucson, but went up in Indianapolis.

Still, there's a modicum of satisfaction in catching up to that aggressive driver - and seeing him on the side of the road in front of a police car - going nowhere fast.

Drive safely everyone.

That's a page from my notebook.
