Primary Local Driving Topic: Freeway and Frontage-Road Driving
Carrollton's defining driving challenge is understanding how frontage roads work around major highways.
A driver can be physically close to I-35E or SH 121 without actually being on the mainline. Frontage roads can have their own intersections, turning movements, traffic signals, and entrance ramps. A new driver should read signs carefully and avoid assuming that every road alongside a freeway provides the same access.
Current city traffic notices also show that interchange construction can change normal routes. In 2026, Carrollton published an advisory concerning closures involving the I-35E and President George Bush Turnpike direct connectors, with detours using SH 121 and the I-35E frontage road.

Students should learn to follow temporary signs during construction rather than following an old route from memory.
