An ordinary driver has 0.60 g/L of alcohol in the blood, with no narcotic use involved. How is this alcohol level classified under the national road rules?

Explicación

For an ordinary driver, 0.60 g/L lies from the applicable threshold up to but below 0.80 g/L, so it is a fourth-class contravention. It has not reached the separate 0.80 g/L boundary that changes the offence category.
