You can now "swap" your parking session onto another vehicle through text.
To transfer your parking onto the second registered vehicle on your account simply text "Swap" to 84555. Alternatively to transfer your parking onto a vehicle that is not registered on your account – simply text "swap *car reg" to 84555 i.e. "Swap YH13WYS".
You will receive a confirmation text stating that the new vehicle is now covered for the remainder of your parking transaction. Just remember to "swap" back if you are reverting to car reg 1 throughout the remainder of your transaction. Please note there is no additional charge for this service except your regular network charge for sending a text.
