If you are using the signal indicator in the vehicle, do not forget to switch if off as soon as you have completed your turning. While changing lanes, put on your turn signal. Make sure through your mirror whether the traffic behind you is sufficiently behind and then change into lanes slowly and smoothly. When other vehicles wish to overtake you, do not speed up. Allow them to overtake if there is space and show a signal by stretching the right hand out, palm facing front and moving the arm front and back.
Most accidents happen due to over speeding and rash driving.
Remember that the speed limit is only the maximum permissible speed and that actual speed should be related to the traffic and road conditions. Front and Rear doors of the car particularly the right hand side door should be opened only after making sure that there is no vehicle, cyclist or even a pedestrian coming along close to the door. In places where it is indicated as accident-prone areas, you must drive very carefully. When there is obstruction ahead, do not drive on the other side of the road without waiting and giving way to the on coming traffic. Never exceed speed limits even if the road is free and even if there is no policeman around.
