A driver above the age of 21 may not operate a vehicle if they have a minimum THC level of ____ per milliliter of blood.
Correct answer
- Zero nanograms
- One nanogram
- Three nanograms
Explanation
It is illegal for a driver who is age 21 or older to operate a vehicle with a minimum THC level of five nanograms per milliliter of blood. A driver who is under the age of 21 may not operate a vehicle with any detectable amount of THC in their blood. The use of marijuana while driving can be extremely dangerous.
Common Driving Test Mistakes
In most jurisdictions where cannabis use is legal, especially concerning driving, a "zero tolerance" policy is in place for drivers. This means that if you are over 21, and law enforcement detects any measurable amount of THC in your blood while you are operating a vehicle, you can be charged with driving under the influence (DUI). The legal limit is generally considered to be zero nanograms because any presence of THC can impair driving abilities. This is different from alcohol, where a specific blood alcohol content (BAC) is the legal limit.
