Freeways are large, multi-lane roads designed for high-speed traffic. They typically have no traffic signals or intersections, allowing vehicles to travel long distances without stopping. Freeways often connect cities and regions, making them essential for transportation and commerce. These roads usually feature on-ramps and off-ramps for entering and exiting, as well as designated lanes for different types of vehicles. Traffic signs and markings help guide drivers, while toll booths may be present on some freeways to collect fees for usage. Overall, freeways play a crucial role in modern transportation systems.
