What is the Minimum Age to Ride a Taxi Alone in the UK?
There is no specific age limit for a child to ride a taxi alone under UK law. When traveling, however, you should be aware of some limitations. Children under the age of 12 cannot ride in a taxi without a child car seat or booster seat. Whenever you book a taxi, inform the driver that you are traveling with a child. It is possible that they will provide you with a child car seat, otherwise, you will need to arrange your own car seat.
Children are generally allowed to ride alone without any specific restrictions. As long as the person who is riding a taxi has enough money to pay for a ride, he or she can travel alone. However, there are some private companies that provide sets of rules for children to ride alone. For instance, all the account holders must be 18 or older. The account holder cannot book a ride for minors unless they are traveling with them. In conclusion, it is fully dependent on the taxi firm, driver, or the circumstances to give a ride to minors alone unless adopting all the precautions.
