What must a driver do on entering a motorway?

When entering a motorway, we must observe the position, route and speed of vehicles on the highway, which have priority, through the rear-view mirrors; and if it is possible to enter, signal the maneuver and accelerate with low gears to gain speed and move progressively to the left without disturbing anyone.

On the other hand, if it is not possible, you should yield and even stop, if necessary, at the beginning of the lane, with meters in front of you to acquire an adequate speed and not be an obstacle.
