You can use a Liber-t tag with a motorcycle with some limitations, the main one being that to avoid being charged as Class 1 vehicle you must use the manual lane and hand over the tag to the person in the toll booth. They will use a barcode scanner to read the tag and will charge you as a Class 5 vehicle. The main advantage is that it saves you fumbling for cash / payment cards with gloves on but you should not use the automated lanes. If there is no manned lane, use the automated Liber-t lane. When using the automated lane on a motorcycles just hold your tag up to the gantry, label side facing you. Take care the vehicle (or other motorbike) behind is not too close as the equipment in the automated lane may register you as a larger vehicle and charge for a car (class 1). You can check your transactions in the 'My Account' area a few days later. If this happens you would need to contact us and request a toll adjustment. If you use the automatic lane then we can only request a toll adjustment if you have used the non-height restricted Liber-t lane, all vehicles using the 2 meter height restricted lane will be classed as class 1 with no option to adjust this
