Numbers to know

3 questions from the Idaho practice test

1. 1. When does an Idaho license marked Under 21 expire?

   1. On the holder's 21st birthday
   2. Five days after the holder's 21st birthday
   3. Thirty days after the holder's 21st birthday
   4. At the end of the calendar year
   Show answer

   Five days after the holder's 21st birthday. An Idaho credential marked Under 21 expires five days after the holder's 21st birthday. The birthday itself is not the expiration date, and the handbook does not extend the credential to a month or the end of the year. The same passage distinguishes an Under 18 credential, which expires five days after the 18th birthday. When checking a card, read the printed under-age notation and its date rather than assuming expiration occurs on the birthday.

2. 2. Which Idaho drivers may choose an eight year license renewal?

   1. Any driver over 16
   2. Only drivers over 65
   3. Commercial drivers only
   4. Drivers between 21 and 62 years of age
   Show answer

   Drivers between 21 and 62 years of age. A renewal is valid for four years or eight years, or to the end of a lawful stay in the United States, and drivers between 21 and 62 years of age may choose the eight year renewal for a Class D or commercial license. Vision screening is required at every renewal, and a failed screening can require a vision exam form from an eye doctor.

3. 3. How can an Idaho driver who is temporarily out of state extend an expiring license?

   1. Drive on the expired license for a year
   2. Renew by phone for free
   3. Apply for an extension of up to 12 months for $10, with one final second extension available
   4. No extension is possible
   Show answer

   Apply for an extension of up to 12 months for $10, with one final second extension available. If you are temporarily out of state when your license expires, you may apply for an extension of up to 12 months for $10, and if necessary a second and final 12 month extension for another $10. Active duty military members and their dependents may apply for as many $10 extensions as needed during the service period. Contact ITD for the application.
