While driving, we all have noticed white and yellow lines on road.But have you ever thought about this?Every driver needs to know the different meanings of those common road markings.Don't panic even if you have no knowledge about it as we have come up with the right information. Different Types of Road Marking:- Broken White Line : Around the country, this is the most widespread type of road used. A broken white line in the middle of the road gives you permission to change lanes, overtake and take U-turns.

You all have seen doctors wearing green or blue clothes in the hospital or in  movies or in web series. Usually,doctors wear such clothes during the operation.

Also continuously looking at red can lead to distracting green illusion on white surface and desensitizes the cones in the eye (cells responsible for colour vision), so l...

There is more than one reason why a judge resorts to this action after he/she has passed the judgement. 1. The practice is symbolic of the belief that a pen which is used to take away a person’s life should not be used ever again for other purposes.The very act of giving the death sentence, or taking the life of someone, is considered so “unholy” that the pen automatically becomes sullied. Hence, the pen is destroyed. 2. After passing the death sentance,Judges have no powers to review/revoke the judgement or order once it has been written and signed.So the nib is also broken, symbolic of the fact that the judge cannot cancel or rewrite the judgement if he/she has a change of heart or mind.   3. It is done by the judge as a way of distancing himself/he...
