I have between 30 and 40 psi while driving. But it drops to below 10 psi when I have to stop at a stop sign or caution light
We have to know which engine...
generally, warm, idling engine, oil pressure should read down to 15 psi
Range, normal driving around 40 ~ 60 psi.
High rps will get upwards around 70 or so...
These are general; your readings are low for normal driving.
Oil pump gears are worn, you should replace oil pump .
Other experts .. comment, please...

30 to 40psi while driving is extremely low. I would suggest getting another oil pump, if the internals will even hold the pressure. It might be time to do an engine swap. Mike. Rate 100% please.
Increase the viscocity of your oil. If you're using 10W30, go to 10W40. If you're using 10W40 switch to 20W50. Don't use single weight oil.
