This switch should only be turned to the off
position if the person in the right front passenger's
position is a member of a passenger risk group
identified by the national government as follows:
Infant. An infant (less than 1 year old)
must ride in the front seat because:
•
my vehicle has no rear seat;
•
my vehicle has a rear seat too small to
accommodate a rear-facing infant seat; or
•
the infant has a medical condition which,
according to the infant's physician, makes
it necessary for the infant to ride in the front
seat so that the driver can constantly
monitor the child's condition.

Child age 1 to 12. A child age 1 to 12 must
ride in the front seat because:
•
my vehicle has no rear seat;
•
although children ages 1 to 12 ride in the rear
seat(s) whenever possible, children
ages 1 to 12 sometimes must ride in the front
because no space is available in the rear
seat(s) of my vehicle; or
•
the child has a medical condition which,
according to the child's physician, makes
it necessary for the child to ride in the front
seat so that the driver can constantly monitor
the child's condition.
