Overnight parking regulations vary by location and parking operator. Each parking operator whom offer the RingGo service apply different rules and regulations.
For example, some locations offer daily parking and allocate a full 24 hours from the time you call RingGo. Others, most predominantly railway stations, split their tariffs into peak, off-peak and dusk until dawn bands; which means that if selecting 1 day, you will only receive from the time payment is made up until the tariff beginning again the following day (i.e. Greater Anglia's tariffs begin at 4:00am so your RingGo session will always expire at 03:59am).
In a completely different concept to station parking, some underground/multi-storey car parks actually physically lock their gates at a specific time and not re-open them until the following day.
To ensure that you have the correct information and have purchased the correct amount of time, you should immediately refer to local signage or contact the parking operator direct. RingGo is merely an automated payment service and we do not set the rules and guidelines appertaining to the parking areas.
