Earlier this month, a new law went into effect in Indiana. Essentially, if you’re driving too slowly in the left lane, you can be ticketed and fined up to $500. The law is designed to keep traffic moving and reduce frustration for drivers who are trying to pass. When it comes to driving etiquette, left-lane-passing-lane is just the beginning. From slow drivers to tailgating to the lack of signals and beyond, we speak with listeners about what drives them nuts. We also talk with Eric Peters, who blogs about all things automotive and has written numerous articles for the National Motorists Association, including “Driving Etiquette: Avoid These Common Driving Errors.” (Flickr/Phillip Capper)
