How to Drive on the Freeway
Freeway, highway, and interstate are terms often used interchangeably, but they actually refer to various roadways that each have their own unique traits. Without traveling down a rabbit hole of minutiae, the main differences come down to lanes, speed limits, location, and which governing body pays for construction and maintenance.
Generally speaking, highways are funded locally, either by the state, county, or city. Interstates, on the other hand, are part of the Interstate Highway System and funded by the federal government. Interstates were developed in part to provide mobility for military operations. This is the main reason why Alaska and Hawaii have them, as they connect military bases, ports, and airports.
In this article, we’ll use “freeway” as the catch-all term and focus on driving tips for multi-lane, restricted-access roads. These will be roadways that connect major cities and require on- and off-ramp usage.
