well its good to go by road to lahore on ur own vehicle.
first image is from NHA and

second image is also from NHA

there is no issue travelling in nights, but better u travelle from midnight to midnight or stay in middle at sadiqabad or any suitable place u want.
in my openion u start your journey from 4am or 3 am because when sun shines you will be near moro or above it, and can travel safely.
motor way police is everywhere and can reach within 5 minutes on superhighway or motorway, so there is no issue
but first of all maintain your ride for long journey,
oil must be changed tires condition must be good.
tools for changing tires must be with you,
medicines for handling emergencies must be with u.
always wear seat belt
always obey warning and safety signs on road,
must have your documents of vehicle with you
must have your driving licence with you.
do not overburden your vehicle with loads of things,
drive save.
and have a pleasant journey
