Between 7.00 am and 11.30 pmThis was the right answer

Some vehicles are fitted with an audible warning device that sounds when the vehicle is being reversed. As these devices make a loud noise, they shouldn't be used between 11.30 pm and 7.00 am in a built-up area. Audible warning devices are an effective safety feature, but they don't take away the need to use effective observation around the vehicle before and while reversing.
