Lancaster Police arrested the driver seen pointing a handgun at another motorist over the weekend.
Lancaster detectives filed the arrest warrant against 49-year old Joseph Benjamin Sida on Tuesday, charging him with deadly conduct, a Class A misdemeanor.
The warrant says that Sida admitted to detectives to pointing a semi-automatic handgun at Victoria Best on Friday in the northbound lanes of I-35E.
Sida was arrested at 3pm by Lancaster Police, according to a statement.
According to the warrant, Sida is licensed to carry a concealed handgun in Texas.
Texas criminal statute defines deadly conduct as a "person who recklessly engages in conduct that places another in imminent danger of serious bodily injury."
State records reveal Sida works as a commissioned security officer.
