Primary Local Driving Topic: I-20 Frontage Roads and U.S. 67 Interchanges
The strongest local driving lesson for Duncanville is learning how frontage roads and freeway ramps work together.
A driver may travel on a frontage road while watching signs for an entrance ramp, exit, turnaround, or cross street. The correct lane may depend on where the driver intends to go next, so reading signs early is essential.
Construction can temporarily change the normal arrangement. Duncanville city updates have documented I-20 detours to frontage roads and U.S. 67 construction involving new service roads and ramps.
Students should practice keeping a safe following distance, checking mirrors before changing lanes, and slowing down when approaching temporary traffic controls.
