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. But you need to ensure beforehand that the road is clear and it is safe to perform.So, dear driver switch the lane only if it's safe to do so. Continuous White Line :   A continuous white line is a tad stricter.It express that you are not all owed to  overtake other vehicles or take U-turns. If you are on this type of road, just keep moving straight.But this rule can vary from one state to another.For e.g in Telangana, a solid yellow line means no overtaking.   Continuous Ye

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 looking at

Since the time of the British Raj,  the custom of  breaking the nib of their pens   after awarding a death sentence has been followed by Indian judges.  But have we ever thought of the reason of doing such an act? 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/herself from the judgement
