Hi my car has been in for its m.o.t when I got it back after passing. I go out for a drive and the car starts to beep. I pull over and lift the hand brake up and down then it stops. Then I go on with my journey. And it can start again. then I repeat the same process. Anyone know what it could be please

Manual or X-shift?

anything on the passenger seat, is the seat belt where it should be any lights on the dash (red one stays on maybe)

no light on the dashboard above steering wheel. there's a yellow circle with a seatbelt in the middle where it shows seatbelts. will try to attach picture later.

Have the rear belts been left fastened ? (they do this when testing/checking the rear belts)
