EICHER SCHOOL HOLIDAY HOMEWORK CLASS – VIII ENGLISH Q1Read the newspaper article and answer the questions that follow: Ban is the correct move 10 Feb 2009, Vikram Sinha The move by the central government to finally introduce an amendment to the Motor Vehicles Act, 1988, prohibiting the use of cell phones while driving, has materialized. It also ensures that there are no loopholes left in the law by including hands-free sets in the ban . Doubtless, there will be those who claim that such devices are safe since they free both hands for driving. It is a false claim. There is an assumption that it is the physical hindrance caused by conversing on the phone while driving that is the main safety hazard. Rather, the issue is the mental distraction of the driver. The US is pushing all its states to implement a similar ban. For evidence, it cites several studies, such as one by the university of Utah, which prove that using hands-free devices is as dangerous as speaking on cell phone without them. Another study cited by the report establishes why this so. It states that conversing with a fellow passenger is not dangerous and many instead lead to greater safety. The reason for this is simple enough . a co-passenger is likely to keep an eye on the road, adjust or stop danger. A person at the other end of a phone connection cannot do this. The conservation will remain unchanged, demanding the driver’s attention and lessening his focus on the road at the moment when he might need it the most. The introduction of such a specific law in India is long overdue. And now that one is finally being introduced, the Ministry of Road Transport and highways is taking the correct step by being thorough.
