Under Peru’s criminal-law thresholds, an ordinary driver can commit the offence of drink-driving when the blood-alcohol concentration is over 0.5 g/L. For drivers providing public passenger, goods or cargo transport, the lower threshold is over 0.25 g/L. The traffic regulations also prohibit driving when alcohol, drugs or other substances reduce the ability to drive safely.
