Texas is one of the more strict states for that definition. One can only be called an engineer with a PE (professional engineering license). So, a EE or a ME cannot put "Engineer" on their business cards or title unless they have a PE. This is fine, but that means 98% of the engineers in the state are not "Engineers". (Most people get around this rule by putting "XYZ engineering" on their business cards ... they can say the title of the department they are in such as "sales engineering", but they can't say "sales engineer" as that would be against the law...) The only big down side is that the state legislature takes their cues from the Civil Engineers as they are all PEs (because their jobs require it), and they are -mostlyfucking idiots.
