As you are aware driving without a valid license is against the law in Texas. chapter 521 of the TX Transportation code gives information on the offense and penalties associated with a conviction of this violation.
Section 521.021 of the transportation code is title License Required. Here it states that a person, other than a person expressly exempted under this chapter, may not operate a motor vehicle on a highway in this state unless the person holds a driver's license issued under this chapter.
If you go on to read more of Chapter 521 you will find that it notes that being cited for a first time offense of driving without a license in TX you will get a fine of up to $200. This section of Texas law does go on to show that if you continue to drive without a license and get cited the penalties get more severe for instance being convicted for a third time of this offense can get you a fine of up to $500 and confinement in the county jail for not less than 72 hours or more than six months.
The state of Texas will collect more money above the fine amount though. Texas has a Driver Responsibility Program which assesses fees for a variety of driving-related offenses. With this assessment program surcharges are due every year for three years for certain convictions of Texas laws. Driving without a valid license comes with a surcharge amount of $100 per year.
The exact amount of the fine would be up to the judge in jurisdiction where the ticket was received for driving without a valid license. So if you were cited for driving without a valid license in Texas you should contact the court listed on the ticket to find out what the total cost of the ticket will be for operating a car as an unlicensed driver. The court can also tell you what other penalties you may be facing at your court date besides the fine.
