1. Changing lanes and merging.
Most beginner drivers are terrified when it comes to changing lanes and merging into traffic. Most people think that the driver on the left must always give way to the right when merging.
But there are two give way rules for this: 1) marked lanes on the road. if your lane comes to an end, you must give way to the vehicle already in the lane you're moving into. 2) unmarked lanes. You must give way to any vehicle that is ahead of you, no matter if you're on the right lane.
Before making any lane change, you must always indicate far enough to give a warning to other road users. Then turn off your signal lights once you've changed lanes or merged into traffic.
Another thing to remember is to prepare to adjust your speed according to the speed limit. You might need to speed up and match your speed to the speed of the traffic, especially when merging into highways.
