Using the De Morgan Rule

!(A && B && C) is equivalent to !A || !B || !C

The expression

boolean noDriving = !(daylight && passenger.age >= 21  && passenger.licensed );

is equivalent to

boolean noDriving = !daylight || !(passenger.age >= 21) ||  !passenger.licensed ;

which can be further transformed to

boolean noDriving = !daylight || passenger.age < 21 ||  !passenger.licensed ;
