As of today, new rules are in effect regarding young drivers holding instruction permits. Maura Browning with the State Revenue Department says the number of hours of behind-the-wheel driving instruction required to graduate from an Instruction Permit to an Intermediate License has doubled from 20 to 40 hours. The driving instructor must still be a parent, grandparent, legal guardian, certified trainer, or a qualified driving instructor. The 40 hours now required must include at least 10 hours of nighttime driving. This is all part of Missouri’s Graduated Driver License program, which starts a new driver with an Instruction Permit, moving to an Intermediate License, and finally to a Full License.
