When travelling straight through the round-a-bout you must indicate LEFT to leave. You put this indicator on when you are just passing the exit prior to the one you want to exit.
The task of great driving is mastering the art of forming good habits.
It's easy to pick up habits from watching others and doing what they do; be discerning - make sure you are influenced only by quality driving habits.
Form habits through correct repetition. Aim to do things the correct way, many times, and don't be satisfied with bad performance.
If you do something a number of times correctly, it will begin to become a habit that works reliably.
If you make a mistake while you are developing your habits, work out why, fix that problem, and keep doing it again the correct way.
Indicate for at least five seconds before you pull out from the kerb.
Indicate for at least three seconds before turning.
Indicate for at least two seconds before beginning to change lanes.
Indicate left before you steer off roundabouts
Look in your rearview mirror before you put your foot on the brake.
Slow down if you can't see what's happening ahead.
Slow down at intersections and look for other cars even if you have right of way.
Look into intersections regardless of having right of way.
Keep your eyes scanning the situation all around you.
Look over your shoulder (head check) before beginning to change lanes and in other situations where vehicles could be in your blind spot.
Always be scanning as far ahead as you can see, identify hazards early
Don’t bend the rules
Come to a complete stop (no rolling) at stop signs.
Ensure your maximum speed is always slightly under the speed limit.
Stop for amber lights unless it is not safe.
Be a careful driver
Stay at least three seconds travel time behind the car immediately in front of you. Leave a space, when stopping behind a vehicle, to drive around it if you have to.
Remember M.I.S.S. everytime you leave the Kerb, lane change or merge
Slow down when approaching green traffic lights and check to make sure no one is running a red light.
