Question

which roadways run parallel to highways to give you time to get up to speed when merging?
a acceleration lanes
b roundabouts
c entry points
d get on ramps

Explanation:

Acceleration lanes are designed to run parallel to highways. Their purpose is to allow vehicles to increase their speed before merging onto the main highway traffic. Roundabouts are circular intersections. Entry points are general terms for where one can enter a road. Get - on ramps are more about the initial connection to the highway rather than the parallel - running, speed - increasing lane.

A. acceleration lanes
