Overtaking often takes place at high speeds and you need to consider many different factors.

If you become uncertain while overtaking, there is a risk of misjudging the situation and overtaking may therefore be dangerous. It is better then to slow down, signal and pull back in, and hold off overtaking until you feel you can safely pass the other vehicle.

Don't wait until you're only one second behind the vehicle in front, that's too close! As always, you should maintain at least a three-second distance.
