Sometimes the best help you can give someone is to encourage them.
It can be hard for a learner driver to prepare for a theory test, learn the road rules, and get enough driving practice. Even if you can’t drive yourself, you can help by making it easy for your family members and friends to learn things properly.
Maybe you could help by asking them questions about the road rules, and checking their answers in The Driver’s Handbook? Maybe you could provide a quiet place for them to study the rules? If they have kids, maybe you could look after them sometimes so they can get more driving practice?
If you have a full driver’s licence with no restrictions or disqualifications in the last 2 years, you could help a family member or friend by being their qualified supervising driver. A learner driver needs to complete 75 hours of supervised driving with a qualified supervising driver.
