When entering an interstate highway, you should:

• Stop, check for cars, and enter when safe
• Check for cars and reduce your speed to 25 mph before entering the traffic lane
• Check for cars, increase your speed to match the flow of traffic, and merge when the way is clear
  Explanation:

  "In most driving situations, you slow down or stop before you enter a busy road, but when entering an interstate, you do the opposite. You must use the merging or acceleration lane to speed up and merge with fast-moving traffic already on the interstate."
• None of the above
