Do expressways have separate lanes for entering or exiting traffic?

Expressways are designed with safety and efficiency in mind, which is why they include separate lanes for entering and exiting traffic. These dedicated lanes, known as on-ramps and off-ramps, allow vehicles to merge safely onto the expressway or leave it without disrupting the flow of traffic. This helps to minimize the risk of accidents and allows for a smoother driving experience.

By having these separate lanes, drivers can accelerate to match the speed of vehicles on the expressway before merging, or decelerate safely when exiting. This design feature is essential for maintaining the high-speed nature of expressways and ensuring that vehicular interactions occur in a controlled manner, thus enhancing the overall safety on the road.

The inclusion of these lanes is a standard feature of expressways, regardless of the time of day or the urban or rural setting, which is why the other choices do not align with the characteristics of expressways.
