Final answer:
In the acceleration lane before merging onto a highway, a driver should speed up to match the speed of highway traffic and signal their intent to merge with a left turn signal.
Step-by-step explanation:
In the ACCELERATION lane before merging onto a highway, a driver should speed up to merge quickly with the highway traffic. This means the driver should accelerate to match the speed of vehicles on the highway for a safe merge. Slowing down to a stop or maintaining the same speed if it's significantly lower could be hazardous, as could stopping before merging. It is also important to sign with a left turn signal indicating the intent to merge.
