So recently I was going to go get a TxTag. I decided to research a little since I am Disabled Vet since many things in our great state are discounted or free for us. Come to find out, if you are a disabled vet and have a DV plate, purple heart plate or a couple other plates, you do not need an EZTag and can use the HCTRA tolls for free. The camera will scan your plate as you drive through the EZTag lanes an zero out your toll automatically. No need to get a tag, just drive through like you have one. One stipulation though is that it has to be an EZtag lane or exit. If you have to go through a lane where an arm has to be raised, you will have to pay the toll. But luckily there are very few of these.
One note though, this is only for Harris County and Fort Bend tollways. Austin and Dallas do not offer this.
