In terms of punctuality (b), (c) and (d) above are applied after taking into account any knock-on delay from the previous sailing. Caledonian MacBrayne is subject to penalty on all cancellations, Level 1 lateness and level 2 lateness after taking relief events into account. There are various relief events agreed by the Scottish Government: for example sailings which were cancelled due to bad weather, in accordance with safety procedures, delays due to the unavailability or operational restrictions of harbour facilities or having to wait for the arrival of other public transport connections. Relief events can also take into account the lifeline nature of the services.
