This would be a good day to fuel up in Nova Scotia.

The provincial regulator invoked its interrupter clause on gasoline and diesel prices at midnight.

On Tuesday, the price of self-serve regular gas is down 6 cents a litre to a minimum of $1.43.

Diesel is down more than 11 cents a litre to roughly $1.50.

The interrupter is invoked when there are significant market shifts in fuel prices.
