Entering a Freeway
Be sure you are using the on-ramp when you enter the freeway. Entrance on-ramps may go up or downhill depending on the position of the street you enter from. If you have made a mistake, signs will say Do Not Enter and/or Wrong Way.
You have to be careful when entering the freeway. You should search ahead for traffic on the ramp as well as for a gap in traffic on the freeway. Always observe the ramp speed limit.
