Most ATVs are not, technically, street legal, so it doesn't matter how old they are. If it doesn't have a license plate, it's not legal for them to ride it on the street period.
Generally, ATVs are not street legal in Colorado. There are only certain counties and towns in the state that do allow off road quads to be ridden on city and county roads. ATVs can be ridden on US Forest Service roads and trails with the purchase of an annual pass from the Colorado State Parks Department. The annual fee for the pass is $25.25.
Yes. ATVs (or "quads") are legal in Texas.
