Riding at dusk, night and dawn is even more dangerous than riding in the day. This is why Endorsement 6 (Learner) motorcycle drivers in the MGDL program are prohibited from riding between the 1/2 hour before sunset until the 1/2 hour after sunrise. The majority of fatal crashes happen after dark, or in low-light conditions.
One of the major problems for motorcyclists driving at night is alcohol abuse. Driving after drinking is a problem for motorcyclists, whether they have been drinking or they are trying to avoid being hit by impaired drivers. Motorcyclists in the MGDL program, regardless of age, are restricted to zero blood alcohol content (BAC) and must not be impaired by alcohol or drugs while riding a motorcycle.
