To renew your commercial driver's license (CDL), you will need to appear in person at one of the offices listed below that handle commercial licenses. You may renew your CDL up to six months before it expires.

Of course, in order to extend the life of your CDL for another period, you will have to fill out an application and again prove your physical fitness to handle a commercial vehicle. This entails two principal actions:

• Ace a vision exam.

• Turn in the DOT medical clearance form showing you are still able to handle behind-the-wheel duties.

The fee in most cases for the renewal is $30, and the CDL is valid for six years (two years if you are 72 or older).

Top Renewing a Hazmat Endorsement

If you are renewing a hazardous materials endorsement, you must pass the hazmat written examination again. A passing score is 80%. You will also need to have another background check and update your fingerprints through the Transportation Safety Administration.

Go to the TSA hazardous materials application Web site and click on "Fingerprint Locations." Scroll down to see the locations in Hawaii. Note that except for the office in Honolulu, the offices perched on the neighboring islands are open only once or twice a month.

Neither Lanai nor Molokai has a fingerprinting office location. You might call the appropriate CDL offices to see what, if any, arrangements can be made. Or you might just need to make a trip to the Maui office.

Note: In the rural locations, it might be best to call first to double-check the testing hours and to confirm the site.
