Critical Failure Factors
The most common reason for failing the Texas exam is confusing the specific 'Right-of-Way' rules at uncontrolled intersections and T-intersections, as well as underestimating the severity of penalties for DUI/DWI offenses.
Legal Statutes & Driving Codes
Texas traffic laws, governed by the Texas Transportation Code, place a heavy emphasis on 'Right-of-Way' protocols, which differ slightly from other states and are frequently tested. At an uncontrolled intersection (one without signs or signals), drivers must yield to any vehicle that has entered the intersection on their right. Uniquely, at a 'T-intersection,' drivers on the street that ends must yield the right-of-way to vehicles on the through street. Additionally, drivers on an unpaved road must yield to vehicles on a paved road, and those exiting a private driveway must yield to all traffic on the public street. The 'Move Over or Slow Down' law is rigorously enforced; drivers approaching stationary emergency vehicles, tow trucks, or TxDOT vehicles with flashing lights must move out of the lane closest to the vehicle or slow down to 20 mph below the posted speed limit (or 5 mph if the limit is 25 mph or less). Texas has a strict ban on texting while driving for all drivers, and drivers under 18 are prohibited from using cell phones entirely, even with hands-free devices, except in emergencies. Regarding alcohol, the legal BAC limit is 0.08%, but Texas enforces an 'Implied Consent' law. Refusing a breath or blood test results in an automatic driver license suspension for 180 days. For minors (under 21), there is a Zero Tolerance policy where any detectable amount of alcohol leads to license suspension. The state also enforces the Graduated Driver License (GDL) program (Phase 1 and Phase 2). Drivers with a provisional license (Phase 2, under 18) cannot drive between midnight and 5:00 AM, cannot have more than one passenger under 21 who is not a family member, and must hold this license for at least six months violation-free before graduating to a full license. Furthermore, failing to stop for a school bus with flashing red lights carries a substantial fine of up to $1,250 for a first offense.
