There are some clear benefits to this proposal. At present, people riding bicycles learn how to ride a bike on their own or from their family members. This means that the vast majority of cyclists are not aware of rules regarding bicycles and can pose threats to other people on the roads by ignoring rules. When people have to take riding test, they all learn about rules. In addition, when people have a riding licence, they are less likely to break rules on roads. This is because they might get fined by the police since they have a licence.
However, this proposal has some drawbacks, which should not be overlooked. When taking a test is mandatory to use a bicycle, some people will be deterred because taking tests requires paying fees and taking classes, which is time-consuming. Consequently, such people might use their cars or other vehicles that run on fossil fuels. This, in turn, increases their carbon footprints. Another problem is that it can put extra financial pressure on the government. To check that all cyclists on roads have taken tests, many police officers should be hired to check this.
In conclusion, making tests for cyclists compulsory, can make all people using bicycles aware of road rules, which can increase road safety. However, this proposal might come with environmental and financial problems.
