About the Colorado Alcohol, Drugs & Impaired Driving (DUI) test
Every question comes with an instant explanation, so a wrong answer teaches you the rule instead of just marking you down.
The Colorado permit exam always includes questions on alcohol, drugs & impaired driving (dui), and they catch drivers who only skimmed the handbook. This set drills that one area until the rule and its exceptions are second nature. You need 80% to pass.
Some Colorado laws catch out-of-state drivers in particular. Handheld phones are banned behind the wheel here - hands-free only. The blood-alcohol limit is just 0.02% for drivers under 21, against 0.08% for everyone else - a zero-tolerance gap the test likes to check.
Every question traces back to the Colorado Driver's Manual - skim the right-of-way and signs chapters before your retake.
