The objective of this study was to quantify the benefits and costs that would arise from mandating the fitment of up to 19 vehicle safety technologies to new cars, vans, lorries, buses and coaches in Great Britain. This will provide the Department for Transport with an evidence base to develop policy options for ministers that are cost-effective and impactful for Great Britain in order to enable safer and cleaner transport while minimising the negative impacts.

This cost-benefit analysis has been undertaken to determine the impacts that would arise from seven interventions, i.e. mandatory implementation of different technology packages, compared with the business-as-usual case, i.e. continued voluntary adoption of the technologies in parts of the vehicle fleet in a market environment where technologies are ;mandatory in the EU for the same vehicle categories. The study quantified and monetised safety, environmental and traffic benefits, and fitment and maintenance costs over a 15-year appraisal period extending from 2025 to 2039.
