Curfews are a ridiculous attack on young peoples' civil liberties The idea that young people should have a time after which they cannot drive, or even go out at all in some places, is a highly oppressive one. The arguments in favour of curfews generally seem to range from "it's dangerous" to "they (young people) have no right to be after X hour".
Both of these arguments fall down in the face of a little critical assessment. The idea that night time driving is more dangerous is essentially ludicrous. Yes, visibility is reduced, that is a given, and yes, there is admittedly a rise in the number of drink drivers on Friday and Saturday nights. However, this should be balanced against the risk reductions that come about as a result of driving late and at night. One of the major factors is the sheer reduction in volume of traffic. Approximately 45% of accidents (google it) involve either hitting another car, or being hit by another car. Driving at night, when there are significantly fewer cars on the roads, will inevitably lead to a lowering of the risks posed by other road users. Additionally, while visibility generally is reduced, in some ways it is increased, such as on unlit roads, going round bends. During the day, there would be no way to know that someone else was approaching around the other side, but at night, their headlights give them away. This also applies to cars pulling out of streets, or away from the curb. All manner of situations which might otherwise cause accidents are easier to spot.
As for the other main argument in support of curfews, that pernicious suggestion that young people shouldn't be allowed to move freely - it is simply socially illiberal drivel. The only reasons given to support this are that young people are more likely to be out partying, or involved in anti-social behaviour, or doing drugs, or having sex. You name it, young people are allegedly doing it. This is, of course, outright discrimination. There is never anything behind it beyond media hysteria, conservative instincts, and the feeling that those who are different are also immoral, and deserving of less rights. These people believe that young people are either so depraved, or so stupid, that they cannot be allowed to make their own decisions about when they travel. It is an outright rejection of their human right to freedom of movement, which is not lessened by their age.
Western liberal democracies are not founded on superstition and gut feelings, but on reasoned argument, and on the idea that all should be equal before the law. Curfews run directly counter to this ideal, and should be abolished. I would hope that all who value the society we are so fortunate to live in would be supportive of this motion.
