What must a learner's permit holder always have while driving?

Answer: B — fully licensed driver in the front passenger seat

A learner's permit holder must always have a fully licensed driver in the front passenger seat while driving. This requirement is essential for ensuring that the learner has immediate access to guidance and support from a qualified individual who can assist in navigating road situations safely. The licensed driver is responsible for supervising the learner, sharing valuable insights, and helping to reinforce safe driving practices. The presence of a licensed driver not only enhances safety but also aids in the learner's education and confidence-building behind the wheel. This supervisory role is crucial, as it allows the learner to gain practical experience while also having someone experienced to refer to in case of any uncertainties or challenging driving conditions. Having this support is a key element of any graduated licensing program, aimed at preparing new drivers to face the complexities of driving.
