We publish statistics annually of motoring offences: Motoring offences: 2021 | GOV.WALES. In table 1 we published broad categories of fixed penalty notices, including seat belt offences, which increased by 26% compared to 2020. A number of other offences increased from 2020 too (some did decrease) which is likely a reflection of the coronavirus restrictions in place at the time.
We publish the longer time series on StatsWales . Here it can be seen that at seatbelt offences in 2021 were the lowest they have been since records began in 2011, except for 2020. The figures increased by 26% compared to 2020 but decreased by 7% compared to 2019.
