Renewing Your CDL in Idaho

Renew in Person

While you might think the process to obtain your Idaho commercial driver's license (CDL) seems tedious the first time around, you will be glad to know that renewing it is far less time consuming.

You still have to appear in person at the county driver's license office, but you will only have to take and pass a written hazardous materials test if you wish renew this endorsement. At this time, the Transportation Security Administration will conduct a background check to assess any security threat. You may also be asked to have a current Medical Examination Report (Form 649-F)


Count on taking the hazardous materials test every time you renew this endorsement and your license. If you want to add it to your CDL, then, of course, you will need to take the required test. As with the addition of any endorsement during your CDL renewal, upgrading means that you will have to undergo proper training and you will also have to pass the appropriate endorsement tests.

You will also be asked to show your proper identification (acceptable proof of citizenship or immigration).


  • CDL (Valid for 4 years): $40
  • License upgrade: $25
  • Additional endorsement: (after issuance of the CDL) $15
  • Knowledge (written) tests: $3 each
  • Skills test $200 ($10 to the county and a maximum of $200 to the skills tester)
