What must you enter into when wishing to exit an interstate highway?

When wishing to exit an interstate highway, you must enter a deceleration lane. This lane is specifically designed to allow vehicles to safely reduce their speed as they prepare to exit the highway. By providing a separate lane for this purpose, deceleration lanes help minimize disruption to the flow of traffic on the interstate and enhance safety for both exiting and continuing drivers.

The gradual reduction of speed in a deceleration lane is crucial for drivers who need to slow down without interfering with the higher speeds of vehicles still traveling on the interstate. This lane also aids in notifying drivers of an upcoming exit, allowing them time to react appropriately and change lanes if necessary.

In contrast, acceleration lanes are used for entering the interstate, facilitating the merging of vehicles onto the highway from an access road. Service roads are designed to provide access to businesses and residences near the highway and are not intended for exiting the highway itself. Rest areas serve as convenient stops for drivers to take breaks but are not involved in the process of exiting the highway.
