In Colorado, teenagers can receive their learner's permit on their 15th birthday if they have completed a 30-hour classroom course and passed their written permit test. For that reason, many teens choose to start their driver's education classes well in advance of their 15th birthday. Under Colorado State law students can begin their drivers education at 14-1/2, and they can take their permit test when they are 14 years and 11 months of age.
