Practise highways and passing →Plan the gap while still on the ramp
SGI describes matching the speed of freeway traffic in the acceleration lane. Look ahead and alongside early enough to judge a suitable opening. Entering much slower can create a difficult speed difference for vehicles already using the lane.
Matching speed remains subject to the speed limit and conditions. It is not a command to accelerate into a blocked space. Continue observing the intended gap, signal and make the final shoulder check before moving across.

Normal travel belongs in the right lane; the left lane is for passing. SGI allows a temporary move to help another vehicle merge when that move is safe. Check surrounding traffic rather than swerving left automatically at every entrance.
As an exit approaches, position safely and signal. Enter the deceleration lane before slowing for the ramp. Shorter deceleration lanes and the tendency to underestimate speed after highway travel make the actual layout important.

Original worked cases
A driver sees an opening while on the entrance ramp, then a truck closes it. The first observation no longer establishes a safe merge; the driver continues assessing the actual traffic.
A car is approaching its exit in the through lane. Braking abruptly there to reach ramp speed can surprise following traffic. The planned deceleration belongs in the exit lane.
The exit is now behind the car. Stopping on the freeway or reversing along the shoulder does not repair the mistake safely. The route continues to the next interchange.
Practise the transition, not just the final lane
Entrance, through lane and exit lane do different jobs. When checking an answer, identify where the car is and whether it is building speed, joining traffic or leaving. This avoids treating every highway manoeuvre as the same lane change.
The free exercises below link that planning to passing and observation. They are independent study aids, not official questions or road-test certification. Read the complete SGI chapter and practise the route with an appropriate supervising driver.
