When you park on yellow lines or in other places where there is a time restriction, you need to display the blue parking clock to show your time of arrival. The clock should be sent to you together with the Blue Badge. If not, you can get a clock from the same council that issued the badge. If you need to use a parking clock, you must display it on the vehicle’s dashboard or facia panel, so that the time can be seen clearly through the front windscreen. The clock should be set to show the quarter hour
period during which you arrived. If there is no dashboard or facia panel in your vehicle, you must still display the clock in a place where it can be clearly read from outside the vehicle.
