Lubbock County, Texas, is now the fourth and largest county in the state to pass an anti-abortion ordinance that would bar pregnant Texans from traveling to access an out-of-state abortion.

Lubbock now joins three other Texas counties — Goliad, Mitchell and Cochran — that have passed similar anti-abortion travel ordinances.

Texas has one of the most restrictive abortion bans in the country, according to the Center for Reproductive Rights. Many Texans are forced to travel out of state — or even out of country — to access an abortion; it is estimated that Texans seeking an abortion have to travel an average of 240 miles each way to access care.

Abortion travel bans are enforced through private civil lawsuits filed against people who “knowingly transport any individual for the purpose of providing or obtaining an elective abortion, regardless of where the elective abortion will occur.” While the pregnant people themselves do not face legal liability, people who help them obtain an abortion could face a civil lawsuit for doing so. Anti-abortion activists have dubbed these ordinances anti-“abortion trafficking” laws.
