US 75
US 75 is one of the major north-south transportation corridors through Collin County. It connects communities including Plano, Allen, McKinney, and areas farther north.
For a new driver, the important skills include entering the freeway at an appropriate speed, checking mirrors and blind spots before changing lanes, maintaining a safe following distance, and understanding how exits and frontage roads work.
Sam Rayburn Tollway and SH 121
The Sam Rayburn Tollway forms a major east-west connection across the North Texas suburban area and connects with US 75 in Collin County. NTTA identifies the Sam Rayburn Tollway as extending to US 75 in Collin County.
A beginning driver needs to understand that a tollway can have several lanes, ramps, frontage roads, and rapidly changing traffic conditions. Toll roads also introduce payment and route-planning considerations that are different from ordinary city streets.
Dallas North Tollway
The Dallas North Tollway is another important north-south route for drivers traveling between the Dallas area and northern Collin County communities.
Learning to read overhead signs early, select the correct lane before an exit, and avoid last-second lane changes is especially useful on a controlled-access tollway.
President George Bush Turnpike
The President George Bush Turnpike forms part of the broader North Texas tollway network and connects communities across several Metroplex counties. NTTA identifies Collin County as one of its member counties and lists the President George Bush Turnpike among its toll projects.
A driver using the turnpike should understand that a route may cross city and county boundaries without the driving environment changing in an obvious way.
US 380
US 380 is particularly relevant in the northern and eastern parts of the county.
TxDOT has been studying and advancing improvements to the US 380 corridor. A current TxDOT project involves a proposed realignment of US 380 from FM 1827 to CR 560 in Collin County, while other US 380 planning has involved the Princeton, McKinney, and Farmersville areas.
This corridor illustrates why a new driver should expect construction, lane changes, temporary traffic control, and changing road configurations as transportation projects progress.
SH 5
SH 5 runs through the McKinney area and connects with important local roads and US 75. TxDOT transportation documents identify projects involving SH 5 and intersections around FM 546 and Eldorado Parkway.
SH 78
SH 78 serves communities in the eastern part of the county, including Blue Ridge and other areas north and east of the more densely developed suburban core.
The transition from urban roads to smaller highways makes SH 78 relevant to students learning how speed, sight distance, lane positioning, and intersection decisions change outside dense suburban areas.
Farm-to-Market Roads
Farm-to-Market roads are a significant part of the county's transportation network. Examples include FM 545, FM 546, FM 982, FM 1378, FM 2551, and other routes.
These roads can change character quickly. A student may leave a developed subdivision and soon encounter a two-lane roadway with higher speeds, fewer streetlights, driveway entrances, farm equipment, or limited shoulders.
