2. Which ability does alcohol undermine first?
Correct answer: Your judgment of how well you are riding
Your judgment of your own riding goes first: you get steadily worse while feeling steadily better, so you ride with more confidence and take bigger risks.

3. How does marijuana affect the abilities a rider depends on?
Correct answer: It distorts the perception of time, space and speed
It distorts your sense of time, space and speed — a serious matter for someone who must read complex traffic and make split-second, precise inputs.

4. What happens to your license if you refuse a breath or chemical test in Mississippi?

5. What does Mississippi's Implied Consent Law mean for anyone operating a vehicle in the state?
Correct answer: You have consented in advance to testing for intoxicating substances
By operating a vehicle in Mississippi you have already consented to testing for intoxicating substances, so an officer with good reason to suspect impairment can require a breath or chemical test.

6. What two choices does the manual put to a rider who is going to be around alcohol?
Correct answer: Do not drink, or do not ride
Control the drinking or control the riding: either do not drink at all, or leave the motorcycle behind and arrange another way home, waiting until your system has cleared the alcohol and the tiredness it brings.

7. Which three factors does the manual name as the main determinants of blood alcohol concentration?
Correct answer: Amount consumed, drinking speed and body weight
How much you drink, how quickly you drink it, and what you weigh. Sex, physical condition and food eaten also play a part.

8. At what blood alcohol concentration is an adult considered intoxicated, and what applies below age twenty-one?
Correct answer: Adults at 0.08 percent or above, with lower limits for riders under twenty-one
Every state treats an adult at eight hundredths of a percent or above as intoxicated, and riders under twenty-one face lower limits, from zero to two hundredths depending on the state.

9. What share of motorcycle riders killed in crashes were found over the legal limit for alcohol?
Correct answer: About twenty-nine percent
Studies put it at twenty-nine percent above the point where an adult is legally intoxicated, with another eight percent carrying smaller amounts — proof that a drink or two is already enough to erode riding skill.

10. At what blood alcohol content is a Mississippi driver under twenty-one treated as under the influence?
Correct answer: 0.02 percent
Two hundredths of a percent or more triggers the state's zero tolerance rule for drivers under twenty-one; at eight hundredths or above the charge becomes a regular DUI.

11. You have had seven drinks over three hours. How much alcohol is still in you at the end of that stretch?
Correct answer: About four drinks
Subtract roughly one drink for each hour: seven less three leaves about four still in your system, and clearing those would take at least four more hours before riding is even worth considering.

12. What does the manual say about mixing alcohol with other drugs?
Correct answer: Combined, they are more dangerous than either alone
The two together are more dangerous than either on its own, and plenty of over-the-counter and prescription medicines carry side effects that raise the risk of riding.
