defensive

A conscientious driver is someone who drives according to the rules of the road.

To be a conscientious driver you should use the horn appropriately. Use it to alert the driver behind or in front of you if you think they may hit you. Change your lanes efficiently and when required. It is a standard practice, to change your lane four to five second before the traffic signal to avoid any inconvenience for the other drivers. In addition to that, if you tend to overtake a vehicle choose the safest/widest part of the road to do it.
