As you may be aware, anti-windshield obstruction laws exist in over half of the fifty states in the United States. It is therefore prohibited to have an object obscuring your view of the road. It may seem insignificant, but you can be stopped and fined for it. As a result, not all car phone mounts are permitted in all states. In New York, for example, you cannot have a phone holder mounted on the dashboard or windshield. You should instead use an air vent mount or a CD slot mount holder.
