But I don't think we have been able to answer the second question:
Is it illegal to trasnsport more than 5 gallons (California) in a car?

I'm searching the California codes as we speak and can't find anything

How many times in the last 20 years or so has a police officer asked
if you were carrying to many gallons of gas in the trunk?
