Question 2

Under New Mexico's implied consent section, what must an officer have before directing that a blood or breath test be given?

Question 3

The liver removes alcohol at a fixed rate. What does the manual say happens when drinks go down faster than the body can clear them?

Accepted Answer

More alcohol builds up in the body and driving is affected more — Because the rate is fixed, drinking faster than the body can remove the alcohol leaves more of it in your system, and your driving suffers more.

Answer

Only reaction time changes, not judgment

Question 4
