3 questions on Colorado’s own driver fitness rules
These differ from the rules that hold nationally — they are the ones that catch out drivers who studied another state’s handbook.
1. In Colorado, a person under 21 commits underage drinking and driving (UDD) if driving with a BAC of at least:
- 0.02
- B0.01
- C0.08
- D0.05
Answer: 0.02. C.R.S. §42-4-1301 makes it unlawful for a person under twenty-one to drive when the person's BAC, as shown by analysis of the person's breath, is at least 0.02 but not more than 0.05 at the time of driving or within two hours after driving.

2. Colorado DUI per se applies when a driver's BAC is:
- A0.02 or more
- B0.05 or more
- 0.08 or more
- D0.10 or more
Answer: 0.08 or more. C.R.S. §42-4-1301(2)(a) provides that a person who drives when the person's BAC is 0.08 or more at the time of driving or within two hours after driving commits DUI per se.

3. Until a Colorado minor driver has held a license for at least one year, the driver generally may not operate between:
- A1 a.m. and 5 a.m.
- B10 p.m. and 5 a.m.
- C11 p.m. and 5 a.m.
- 12 midnight and 5 a.m.
Answer: 12 midnight and 5 a.m.. C.R.S. §42-4-116 provides that a minor driver shall not operate a motor vehicle between 12 midnight and 5 a.m. until the driver has held a driver's license for at least one year, with listed exceptions.

2. Driving while very angry or upset is dangerous because strong emotion:
- AHas no measurable effect

- ANoticing signs sooner
- BChecking mirrors more often
