You might know that it's a state law here in Louisiana to use the left lane only for passing, but you might not know why this is so important. The video above explains that slow - moving vehicles in the left lane lead to more crashes because faster vehicles will attempt to get around them, increasing the chances of crashes. The video also has statistics about the number of crashes caused by slow - moving vehicles in the left lane.

It's also important to note that this doesn't just apply to driving on the interstate. Take a drive down Ambassador Caffery past its intersection with Verot where the speed limit jumps up to 55. I've seen people doing what had to be 40 or slower in the left lane and people racing around them to get by.
