Re: Smoking in cars
I spoke to a policeman friend of mine about this.
He has been instructed to give verbal warnings only.
... mind you, if you get all stroppy with a police officer, he might just use his discretion and give you a fine as well.
Incidentally, it is up to the driver of a vehicle to ensure that the passengers obey the same rules. If one of his passengers is below the age of 18, then no other passenger may smoke either.
