How long are written knowledge test scores valid for entry-level learner permit applicants?

The validity of written knowledge test scores for entry-level learner permit applicants is set at 18 months. This means that if a candidate passes the knowledge test, they have up to 18 months to apply for their learner's permit using that score. This time frame ensures that the knowledge remains fresh and relevant, encouraging new drivers to begin their practical driving education within a reasonable period after demonstrating their understanding of the rules of the road.

The other options—6 months, 12 months, and 24 months—do not align with the regulations set forth in the Utah Driver Handbook, as they either provide a timeframe that is too short, which could hinder applicants who need more time to obtain their permit, or too long, which may not reflect the need for updated knowledge as driving laws and regulations can change over time.
