Hands down the easiest roads to drive on, in my opinion.
Always check mirrors frequently. I find myself checking mirrors more than looking infront of me tbh, if there's any incident in front of me I need to swerve away from then I know my surroundings and which way I can divert.
Always check blind spots! I have a blind spot light on my mirrors, but I still check blind spots. They are so important.
Don't go too slow, but go at a speed which is good for you. 60mph is a good speed to familiarise yourself with the roads.
Take care of speed if you're driving on Smart Motorways and other variable speed limit stretches.
Don't lane hog. Move to the left when you're not overtaking.
Lane disipline. As you would on a roundabout, look where the lanes are taking you. You'll know if the lane your in is branching off if the road marking lines change from being spaced to more frequent and closer together.
Keep your distance from the person infront of you, whilst always anticipating for any hazards or incidents that may happen around you.
