New year, new laws: world will wake up to raft of changes in 2014

Countries around the world are ringing in the new year with a host of new regulations, appointments and legislation Here are some of the most important and most intriguing

If it feels like you're waking up to a slightly different world on Wednesday, then it's because you will be. 1 January is habitually a watershed for new rules, appointments and bylaws; 2014 is no exception

So what is changing? Well, if you are driving in Oregon with children in your car, do not light up. It'll be illegal. And if you're driving in Switzerland, turn your headlights on. Even if it's the middle of the day

While we're on the subject of lighting, if you live in Canada please remove those last incandescent lightbulbs – they won't be allowed any more

Other things that are now to be banned: owning unregistered assault weapons in Connecticut; harassing celebrities and their children with long-lens cameras in California; hunting elephants in Botswana and injudicious calls to the London Fire Brigade (if you're a business you'll be fined for false alarms).

In a less-observed border relaxation, it will become much easier for Chinese tourists to visit Taiwan as the Chinese authorities make a concerted effort to improve cross-strait ties

And in the unlikely event that you are off to do some shopping in Latvia, leave your lats at home and take euros instead: the Baltic republic becomes the 18th country to join the single currency zone

Indeed, institutional changes are a 1 January perennial. Russia takes over running the G8 for a year while Greece gets its turn to lead the EU. Democrat Bill de Blasio takes over as mayor of New York. And Barack Obama's new system of healthcare coverage, known as Obamacare, is formally launched with hundreds of thousands of newly insured Americans presenting a formidable test to a system that has endured a difficult birth
