When entering an interstate highway, you should:

Rather than stopping (as you would when entering other roads), you must use the merging or acceleration lane to speed up and smoothly merge with fast-moving traffic already on the interstate.

• 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.
