Is a motorcycle license considered one of the taxes that can be avoided, and is riding a father's unlicensed motorcycle considered a sin?

Using a bicycle without paying its license fees is permissible, but it is not advisable if it leads to penalties or accountability, as a Muslim is forbidden from exposing himself to harm or his wealth to loss. Vehicle license fees are considered taxes, and they are permissible if the state's resources are insufficient for the nation's needs and are spent on public welfare. In this case, they must be paid. The parent should be gently and wisely advised to pay the required fees.
