Explanation:

When getting off the highway, the first step is to get into the exit lane. Speeding up (either to be in front of slower - moving vehicles or to "see how far one can fly") is dangerous and not a proper action. Slowing down to the new speed limit is a step that comes after getting into the exit lane.

Answer:

get into the exit lane
