What is the correct technique for teaching a student to navigate Texas frontage roads (service roads)?

1. Frontage roads are the same as regular city streets with no special instruction needed
2. Teach students about frontage road right-of-way rules, turnaround lanes, entrance/exit ramp interactions, and the unique Texas traffic patterns on service roads
3. Avoid frontage roads entirely during lessons
4. Frontage roads do not exist in Texas
