The exit for the 5 North from the 110 freeway is a left exit with a wicked left turn. This means that a) people unfamiliar with the area don't know to be in the left lane to make the exit and b) because of the sharp left turn, everyone has to slow down to <25mph and traffic backs up making the exit difficult to merge into if you're late getting into the lane. It's a bad interchange because that one lane can back up for a mile during rush hour. It's such a poorly designed exit that Caltrans recently added in lights to the lane divider in the pavement to signal that people cannot merge into that lane within about 1/4 mile of the exit during rush hour.
