TRL were commissioned jointly by Transport Scotland and Department for Transport to undertake a study to provide data on the use of seatbelts by vehicle occupants and the prevalence of mobile phone use by drivers. This data was analysed in-house by Transport Scotland and DfT with reports published at the end of February 2015.
The 2014 seatbelt survey resulted in 7,732 vehicle occupants being observed in Scotland, whilst the mobile phone survey recorded the behaviour of 13,493 drivers.
- The proportion of car drivers observed using their seatbelt correctly in 2014 was 97.8%, an increase from the 95% recorded in 2009.
- The seatbelt wearing rate amongst rear seat car passengers has increased from 88% in 2009 to 99.0% in 2014.
- The proportion of car drivers observed using a mobile phone whilst driving was 1.3% at moving (free-flowing) sites and 1.6% at stationary (traffic light controlled junction) sites.
- The mobile usage rate at moving sites by drivers of 'Other vehicles' (vans, lorries, buses, coaches and mini-buses) was notably higher (2.9%) compared to car drivers.
- Drivers were more likely to be witnessed with a mobile phone in their hand than at their ear.
